Mount St Helens
I predict that Mount St Helens will return to the way it was before the eruption, because plants and animals and trees are coming back to live there. About the part of the mountain that fell of in the big eruption, I believe that someday, either the peice that remained in the eruption will blow off in another eruption, the cause being it would be the same, but it would be a smaller volcano, or the rocks would pile up again and make themselves somlid again to re-create the "illusion" at least that the volcano was back to normal. As for the wild-life, yes, I do think that they will return back like before.

That does make sense, because if you think about it, it probably won't look the same. Thanks.

I think to same thing about mount st helens. I do think that one day it will rebuild sometime in the future. I don't think it will come back exactly like it was before

Acidic and basic are two extremes thatdescribe chemicals, just like hot and cold are two extremes that describe temperature. Mixing acids and bases can cancel out their extreme effects; much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral.
The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline—another way to say basic—than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9.
