Do mountains last forever? Explain why with as much detail as you can. What causes them to last forever or not last forever?
Explain at least two ways that solid rock can break into smaller pieces naturally?
How are rocks at the top of a mountain different than the ones at the bottom? What makes them that way? How did our experiment demonstrate that?
Mountains do not last forever because of trees and other plants.
One way solid rock can break into smaller pieces naturally is by tree erosion. This means that trees can erode rocks. Another way solid rock can break into smaller pieces naturally is by ice erosion. This means that ice can erode rocks
Rocks at the top of a mountain are sharp. Whereas rocks at the bottom of a mountain are round. The rocks at the bottom become this way by erosion. Our demonstration showed us that by showing us what happens when rocks roll down a mountain
