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/do not last forever because Mountains do not last forever because over time mountains erode away.
One way solid rock can break into smaller pieces naturally is by root wedging. This means that When a seed drops in to a crack in the ground and it starts to grow the roots split the ground. Another way solid rock can break into smaller pieces naturally is by Ice wedging.
This means that when it rains the water go's into a crack and it freezes and breaks the rock.
Rocks at the top of a mountain are big,sharp and some of them are boulders. Whereas rocks at the bottom of a mountain are small , smooth pebbles. The rocks at the bottom become this way by rolling and rolling down the mountain and eroding away the sharp edges. Our demonstration showed us that by the sugar cubes edges got eroded away by them rolling a bunch.
