Mt. Saint Helens will eventually grow back its lava dome. It is constantley errupting rebuilding its base. The composite volcanoes are also called strato volcanoes and are formed by layers of rock. The shield volcanoe is often shallow slopes at sides and is made from fluid lava. Cinder cones are steep conical hills that build down from a volcanic vent. Block lava moves slowly and are stronger and thicker. Pahoehoe lava is thin sheets of lava and are smooth fast flowing and thick. Aa lava flow is rough and animated with burst of energy.

I will start out with volcanoes then lava. First an example of a composite volcano is Mt. Saint Helens! Our volcano! These volcanoes are many miles wide and several thousand feet high. They consist of layers of solid lava flows mixed with layers of sand- or gravel-like volcanic rock called cinders or volcanic ash.

A cinder cone volcano these volcanoes consist mostly of loose grainy cinders and no lava. They are smaller than the usual composite volcano. A shield volcano is what makes up the islands of Hawaii. The lava is frozen and big craters at the top.

Now onto lava! Low water/low silica is a type of lava that is really runny not like water but more like hot wax or warm honey. When these types of lavas erupt they can flow for long distances before solidifying.

Low water/high silica lava is very "pasty" like soft clay and hardly flow at all ending up with a tall, narrow pile of lava. This type of lava is high in silica, or quartz, and tends to stick together.

High water/low silica lava has low viscosity and bubbles and froths a great deal right at the surface. It produces tiny cinders and larger "bombs" of lava that quickly cool and fall back to the ground. This type of eruption creates a spectacular "fire fountain" at the top. The remaining lava quietly flows away.

The last type of lava is high water/high silica this type of lava is inside the mountain known as Mt. Saint Helens! As the lava oozes to the surface, the gases quickly form bubbles that turn the lava into a red-hot froth that explodes out of the ground. A hot grayish cloud of superheated steam and tiny particles called ash is what makes up the explosion.

I am going to tell you about some different types of valcanoes. Composite valcanoes have steep sides. They also have a layer of lava that is mixed with sand. The lava and sand is what builds the valcano.

  A sheild valcano is hundreds of miles wide and ten thousands of miles high. Sheild valcanoes consist almost entirely of frozen lava, and have low slopes. this valcano also has large craterson the summit.

  The gint caldera is the largest of the valcanoes. This valcano can be as big as the yellow stone park! they can blow ash out thousands of miles away!

 The last valcano is called a cindercone. It is made of loose gravel, sand and has barely any lava. This valcano is miles wide and thousands of feet high! When this valcano eurups it shoots out cinders and that is how it got its name!

   and those are most of the valcanoes and their lavas

I learned that there are alot of types of Volcanos! There are alot of types of lava too. Our group had fun drawing all the pictures and reading all about how valcanos erupt and what happens when they do. I learned alot about valcanos and lava. Some valcanos when thet get damage done to them when the erupt and get smaller most of the times they don't grow back to there normal size. Just like Mt. St. Helens!

What I learned about volcanoes.......!  First I learned that  Composite volcanoes can usually get up to tens of miles across and up to ten thousand or more feet high!  The Cinder cones are usually small volcanoes, about a mile across and about a thousand feet high. They usually have a small crater on top.Now the last volcano....... the Shield volcano, how interesting? It usually gets hundreds of miles across and tens of thousands of feet high. They almost always have large craters at thier summits. Next up, finnaly the LAVA=http://=http://!!!  There are 4 types of lava.. there are Low water/ Low silica, Low water/ High silica, High water/ Low silica and High water/ High silica. Ok to me neither lava or volcanoes are cool unless it is MT. ST. HELENS! How cool is that volcano!  10,500 out of 100. Mt. st. Helens is a  COMPOSITE  volcano, and it's type of lava is Low water/ High silica!!

You can enter the Mt. Saint Helens will soon grow back its lava dome. Its always errupting rebuilding its top. The composite volcanoes are formed by layers of rock. The shield volcanoe is often shallow slopes at sides and is made from liquid lava. Cinder cones are steep conical hills that build down from a volcanic vent. Block lava moves slowly and are  thicker. Pahoehoe lava is thin sheets of lava and are smooth fast flowing and thick. Aa lava flow is rough and animated with burst of energy!

    There are five different types of volcanoes. Composite, cindercone, shield, caldera,and fissure volcanoes.

  Lets start with composite volcanoes. A composite volcano is made up of solid lava in layers like a cake.  It becomes taller with every layer.  Some composite volcanoes include Vesuvius, Krackatoa, Fujiyama,and Mount st. Helens.  They have fairly steep sides and they are ten thousand feet tall or more.

 Next are the cinder cone volcanoes. A cinder cone volcanoes are almost entirely made of loose grains of cinders. They are small for a volcano but I'm not saying that they are small compared to us. Cinder cone volcanoes only get up to one tousand feet tall.

  Now we are going to talk about shield volcanoes.  Shield volcanoes can be hundreds of miles across. Shield volcanoes are made from frozen lava. Most of the time they have large craters at the top.  Another type of volcano is "Giant" or caldera.  The caldera volcano is a huge crater it can be many tens of miles across.These craters are on other volcanoes. They form by collapse.

  The last type of volcanoes.  Fissure volcanoes are cracks in the earth that spew out lava.The lava then pools and becomes solid and most of the time covers the crack.   

    

 

Sheild valcanoes are hundreds of miles wide and ten thousands of miles high, they also have low slopes and consist almost entirely full of frozen lava! Compostile valcanoes are really steep. they also have a layor of lava that is mixed with sand!Gint caldera is the biggest of all the valcanoes, this valcano can blow out so much ash! the cinderdome valcano is made out of loose gravel and sand so it doesnt have hardly any lava. This valcano is thousands of miles high!! Ok this is all about the kinds of valcanos!!!  

In Mr. Gonzalez's class we learned that ther is 3 different types of volcanoes and 4 different types of lava. Well thefirst volcanoe I learned about is the  Composite volcanoes and they can can usually get up to tens of miles across and up to ten thousand or more feet height. Next, is the Cinder coneand are usually small volcanoes, about a mile across and about a thousand feet high and they usually have a small crater on top.The Shield volcano, gets hundreds of miles across and tens of thousands of feet high. Next up, there is Low water/ Low silica, Low water/ High silica, High water/ Low silica and High water/ High silica. The Hawaiian islands are high water and low silica and Mt. St. Helens is low water and high silica. By Dominic B

Here's what I learned about volcanoes. First, the Composite volcano. These types of volcanoes are usually tens of miles  and ten thousand or more feet in height!

The Cinder cones are small volcanoes, usually about a mile across and up to about a thousand feet high. These kind of volcanoes usually have a small crater on top. O.K. Enough about volcanoes. Here's what I learned about lavas. There are four types of lavas. There are Low water/ Low silica, Low water/ High silica, High water/ Low silica and High water/ High silica. Did you know that some lavas are very runny?!? At first I thought that it would be runny like water, but it's not, it's like hot wax! You learn something new everyday. No Duh=http://!!

       Mountains like Vesuvius and Mt. St. Helens have lava that has a high water/high silica content. This is a deadly combination for as the lava oozes to the surface, the gases in it quickly form bubbles that turn the lava into a red hot froth that explodes out of the ground in a searing grey cloud. There is also another lava that has a low water/low silica content. This is a very runny lava that spreads far and wide and runs long distances before cooling. This sometimes results in creating new  shield volcanos. Another lava, unlike the other ones, has a low water/ high silica content. This lava is very pasty and has a high viscocity which means it's very thick and slow. The lava slowly oozes out to form a bulbous dome that hardly moves at all. After a while it may form tall steep stratos volcanoes. The last lava has a high water/ low silica content. This lava bubbles and froths alot and sometimes comes out as a fire fountain over the vent. What also happens is that the vent spits out tiny cinders and large "bombs" of lava that cool very quickly. That's what I have for lava! Now it's time for volcanoes!

            Mt. St. Helens is a Composite volcano. These volcanos are typically tens of miles across. and ten thousand or more feet in height. they have moderately steep sides and sometimes have small craters in their summits. They consist of layers of solid lava flows mixed with layers of sand or gravel-like volcanic rock called cinders or volcanic ash. Another type of volcano is the Cinder Cone volcano. Cinder Cone volcanoes consist of loose grainy cinders and almost no lava. They are only a mile across and up to a thousand feet high. They have steep sides and usually have a small crater on top. A different type of volcano is the Shield volcano. They can be hundreds of miles across and many tens of thousands of feet high. They consist almost entirely of frozen lavas. They almost always have large craters at their summits. The Caldera volcano is very wide and isn't tall at all. They are up to tens of miles across and look like big craters. They can spew rock hundreds, and maybe even thousands of miles in all directions. Finally, last but not least, the Fissure Volcano! These volcanos are really just giant cracks in the ground. The giant cracks expel vast quanities of lava that spread far and wide to form huge pools that can cover almost anything around it. When the lava cools, the surface is completely flat. And that is My AMAZING Volcano/Lava Project.

    The Composite Volcano has lava flows on the sides of the volcano. The sides of the volcano is filled with rocks and  ash all arownd the hole thing. The Cinder Cone Volcano when it is thick and strong it dose not seperat from it's form. The Shieid Volcano it can get up to five or more lares of lava around it. High Water High and Silica Volcano it make the lava fast and smoth covering homes and even bildings. High Water and Low Silica which makes a some what big boombut wont go very fare in range. Low Water and High Silica the bubbles make it go up with more liquid in littel bits in the sky. Low  Water and Low Silica all of the silica is low and the water is too, it gose very slowly tring to get out.

So 3 types of volcanoes are1: Composite volcanoes which are, ten thousand ore more feet high. They are considred a hollywood type volcano, they are also the large size of ten miles across. 

#2. A Cinder Cone volcano, they are pretty small volcanoes. The amount of lava is close to none,this volcano also has very grainy cinders.

#3. A Sheild volcano, they aremostly found in differen't parts of Hawaii. It is a very wide volcano and is also thousands of feet high. The kind of the Shield volcano has the biggest volcano in the world.

three kinds of lava are,

#1. The Low Water/Low Silica lava is mostly a pretty runny lava type, so technicaly it has alot of visocity. It is not runny like water but more realisticly like hot honey or hot wax.

#2. The High water/High silicahas lts of disolved gasses and its high viocity is deadly.as the lava ooze's to the surface, the gasses quickly become bubbles. 

3. High water/low silica lava shows behavior's that are similar to our anoligies of blowing bubbles in water or a milk shake. If a erupting volcanohas low viocity (like water) it flowsout of the central surface.

Three types of volcanoes are:

1. Composite volcanoes which are, ten thousand ore more feet high. They are considered a Hollywood type of volcano, they are also the large size of ten miles across.

2. A Cinder Cone volcano, they are pretty small volcanoes. The amount of lava is close to none, this volcano also has very grainy cinders.

3. A Shield volcano, they are mostly found in different parts of Hawaii. It is a very wide volcano and is also thousands of feet high. The kind of the Shield volcano has the biggest volcano in the world.

Three kinds of lava are:

1. The Low Water/Low Silica lava is mostly a pretty runny lava type, so technically it has a lot of viscosity. It is not runny like water but more realistically like hot honey or hot wax.

2. The High water/High silica because of its dissolved gasses and its high velocity is deadly. As the lava ooze's to the surface, the gasses quickly become bubbles.

3. High water/low silica lava shows behavior's that are similar to our analogies of blowing bubbles in water or a milk shake. If an erupting volcano has low velocity (like water) it flows out of the central surface.

Hope you enjoyed!!

Hi im here to talk about volcanos and lava flows! Ready? Ok! Fist one is a shield volcano, they are big and round (duh) its not very steep so the lava has drag but with low silica (30% to 50%) it can go A LOT faster even if its a shield volcano. Your probably wondering what silica crystals are, well i dont know very much either but i'll tell you what i know, silica is in some volcanoes they slow them down, if theres more H2O then silica it will be very runny like in hawaii AA has very low silica in its base causing it to go very fast. There are also some different lava flows like a lava fountain, by the name your guessing it spews out tons of lava, if you did your half right! Lava fountains have to be very liquidy so it can flow out so more H20 has to be added. There is also the lava hose, it is this stream of lava coming out of a crack in a mountain it most likely has very low silica. Enough with all the lava flows lets get back to volcanoes, there is two last types i want to share with you before i have to work on different things, theres a cinder cone volcano, it is very steep so the lava flows faster unlike the shield volcano, the cinder cone volcano hardly has lava flows so the silica peaks up to about 60% to 70% silica! Think of the massive explosion! Here is the last one, i promise! Its a composite volcano, it starts or ends with a shield cone then to a cinder cone type, our mountain Mt. St. Helens is a composite volcano it has high silica in it too so it buildt up and caused both an explsion and a lava flow. Hope you liked this LONG report, i tried to make it interesting! =D

Lava

I learned that high silica makes lava flow slower. Low silica makes lava flow faster. High water and high silica makes a huge blast. Lava can get really hot. I saw that it can get up to 500 degrees and hotter. Sometimes when lava oozes from a volcano to the ocean it gets hard and turns black. Steam rises from the water.

Volcano

Mt. St. Helens is a composite volcano. There are three main types of volcanos. Cinder volcanos, shield volcanos, and composite volcano. The shield volcano can be 200 ft. wide=http:// Some volcanos can be hundreds of feet wide but thousands of feet tall! Thats pretty cool!

Volcanoes......and......LAVA

Ok here I go about Volcanoes. The first type of volcano is called acomposite volcano, these volcanoes are made up of a mixture of cinders and lava flows. These volcanoes are very explosive there lava is High sillica/High water. This  lava is very slow moving and can clog easily to make the volcano eurupt explosivly. The second type of Volcano is the shield volcano. They have slanting sides and usally really tall they have aa and pahoehoe or low sillica/highwater and low sillica/low water lava. The last type of volcano is the cindr volcano.These volcanos are made of cinders(Duh :) and vertully no lava flows. They have tall sides and have high sillica/low water. Hope you liked my report. : ]

The first type of volcano I learned about was composite volcano. Are typically tens of miles across, and tens of thousand feet of height. The next volcano I learned about is the cinder cone volcano. The cinder cone volcano mainly consists almost entirely of loose grainy cinders and almost no lava. Another volcano I learned about was the shield volcano. The shield volcano is type of volcano that can be hundreds of miles across and many tens of thousands of feet high. This volcano is mainly found in Hawaii. The next volcano I learned about is the caldera Volcano. Calderas, which are simply circular depressions that are found in summits of many volcanos. The last volcano I learned about is the fissure volcano. Fissure Volcanos make large cracks in the ground instead of a giant crater like most volcanos.

I also learned about different lava types. The first lava type I learned about is low water/low silica. Low water/low silica is lava that is very thin and runny lava. The next lava I learned about is low water/high silica. One of the most important factors is composition espescially the amount of silica melted in lava results in a thick lava. Another lava type I learned about is high water/low silica. This type of lava (high water/low silica) produces a spectacular “fire fountain” directly over the vent usually resulting in a cinder cone any remaining lava quietly flows away. The last type of lava is high water/high silica. This type of lava causes explosions eruptions at volcanos like Vesuvius and Mt St Helens.

In class we learned about volcanos and lava tyes. I had an okay time doing this assiment. We learned about different types of volcanos and lava. Composite volcanos are fomed by altering layers of lava and rock fragments. Another type of volcano is Shield volcano. They are huge in size, they are built by many layers of dry runny lava flows. Cinder Cone volcano. They are a steep conical hill formed above a vent. They are among the most common volcanic landforms foumd in the world. Mt. St. Helens is a Cinder Cone volcano. Now you know some things on volcanos.

i learned lots about valcanoes. Lots of the lava looked like marsh mellos!!!.Composite valcanoes have steep sides.it has a layer of lava and lava with and mixed in with it.It also hase small craters.The lava with sand bilds the valcanoe. It is about 1000 of miles wide and another  1000 miles high.the lava looks like marshmellos!!

  Two things what i learned about volcanoes and lava,and what are they.

    Frist of all i learned that there are different kinds of volcanoes, like the low water and low silica.I also learned that the different kinds of level on water and silica makes different kinds of eruption.

   Lava is what the volcanoes blow out of there tops.Volcanoes are like mountains but mountains do not eruption, but volcanoes do. Mountains in some ways are drangers but volcanes are drangers when they eruption.
