Welcome to Mr. Ullrich's Blog! This blog is for 8th Grade Earth Science and Physical Science students. We will learn topics such as Astronomy, Geology and Meteorology. This blog will give us a place to discuss, learn and develop these topics during the year. If you are not from our class please post lots of comments!

Global Warming is a climate change in the atmosphere of the Earth. It is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the green house effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. It is believed by many people that humans are causing this change and are slowly killing the Earth because global warming hurts many people, animals, and plants. Many people also believe that humans are causing Polar Bears to go extinct because glaciers are melting because of global warming.
The greenhouse effect makes the earth appropriate for people to live on. If we didn’t have greenhouse gasses, then either the world would be freezing or would be burning hot. Even though the greenhouse effect makes the earth able to have people living on it, if there are too many gases, the earth can get unusually warmer and many plants, animals, and people can die because of this! You definitely do not want this to happen! People and animals would die because there would be less food for animals, like cows and grass, and therefore less food for us! Everyone could die of hunger!
Greenhouse gasses are gasses that collect heat and light from the sun. If there are too many greenhouse gasses in the air, then the earth’s atmosphere would get too hot. People, animals, and plants would die because of the heat. Global warming makes the sea rise and cover low land islands. Global Warming also kills life in oceans.
I think humans are contributing to global warming but are not the main reason of global warming. Humans contribute because of the pollution they cause. Things such as electricity (light, T.V., using a hair dryer, etc.), riding in a car, using a microwave, etc. cause global warming. When garbage is burned in landfills, it sends greenhouse gasses into the air.
Many people simply believe that global warming is natural and the Earth is actually cooling. Many people believe polar bears will not go extinct and humans aren’t a big cause of global warming! It is natural for the climate to change and temperatures will fall not rise!
Which side areyouin the argument? I believe that humans are not the only cause of global warming, but we can still help!

Mars is worth exploring because it has a slight possibility that it can support life and humans can live there on day. This is because Mars might have frozen water under its surface. There is a lot of effort for exploration on Mars and people are trying to find a way to go to Mars to try to make it suitable for human life. In my opinion, it would be great if life on Mars succeeded, but it will take a very long time and is pretty unlikely because of the money it takes to do everything and also the way of getting to Mars. Scientists believe that Mars was very similar to earth with oceans and rivers long before humans.
Mars is the fourth planet in our solar system. It has a reddish appearance. It has a thin atmosphere and is similar to Earth in some ways. It has two moons Phobos and Deimos. They are very small and irregularly shaped. Mars is mostly made up of red soil, and rock. It is a terrestrial planet. It is less dense than earth but it’s surface area is only a little less than Earth’s amount of dry land. It has a lot of interesting terrain including a mountain/volcano called Olympus Mons. Olympus Mons rises 24 km or 78,000 feet above the surrounding plain. It’s base is more than 500km in diameter and it’s cliff/rim is 6km or 20,000 high. It takes Mars 24 hours and 39 minutes to rotate on its axis and 686.971 Earth days or 1.8808 Earth years to fully revolve around the sun.
1. Mars was named after the Roman God of war, Mars.
2. If humans were to come to Mars, it could be terraformed (the climate, surface, and properties of Mars would become habitable by humans and other life). This is how it would look like!
3. Mars is sometimes referred as the Red Planet.
4. The name of the month March comes from the planet Mars.
Mars distance from Earth varies. Both planets travel around elliptical orbits that are not very synchronized, so they are constantly getting closer together and farther apart.
How was it discovered: Mars is a lot like Venus, it is very bright and very easily seen in the night sky. We do not know who actually discovered Mars. Scientists most likely observed it and figured out it was a planet. However, Mars moons were discovered. In 1877, Asaph Hall spotted the two moons and named them.
