Does Erosion ever stop?
NO!
When the small pieces are deposited in a new location.
What is:
DEPOSITION
Is weathering a slow change or fast change?
Slow change
Can erosion happen before weathering?
No, weathering must occur first, then the broken pieces are carried away.

What happens when water gets inside cracks of rocks and freezes?
The rocks split open (frost wedging)
Rock worn down by friction or impact.
What is:
Abrasion
Explain the difference between chemical and mechanical weathering.
Mechanical weathering is the breakup of rock without changing its chemical composition.
Chemical weathering is the breakdown of rock by changing its chemical composition.
Erosion can be caused by what forces?
What is:
1. Wind
2. Ice
3. Water
What is the difference between Erosion and Deposition?
Erosion is the process by which small pieces of rock and soil are moved.
Deposition is When the small pieces are deposited in a new location.
What is the difference between weathering and erosion?
Weathering is the process of breaking parts of the earth down Erosion Gets rid of the elements of the earth that have moved and are left behind.
