question
weathering
answer
when rocks at the earth's surface breakdown and get smaller
question
mechanical weathering
answer
happens when the rock is broken and weakened in its physical structure
question
Chemical weathering
answer
chemical structure broken down possibly changing the minerals within that rock
question
Acid rain

answer
windblown deposits of mineral-rich dust and silt
question
Glaciers
answer
slow moving sheets of ice
question
Moraines
answer
ridge like piles of rocks and debris
question
How can the landscape be changed by physical and chemical weathering?
answer
Mechanical weathering may break down parts of the crust and chemical weathering may change the rocks on the crust into new things.
question
How can the processes of erosion(wind,water,and glaciers affect the landscape)?
answer
If there was soil in one place erosion by water and wind could turn it into a desert.
question
