Weathering
What is weathering?
Weathering is the process that breaks down rock and other substances.
What is erosion
Is the process of wearing down and carrying away rocks.
What causes Mechanical weathering?

What is the difference between weathering and erosion?
Weathering is the breaking down of rocks, and erosion is the moving of weathered material from one place to another.
The dropping of sediment and rocks in a new location is called _____.
What is deposition?
How does water causes mechanical weathering?
Water cause mechanical weathering when rivers waves cause rocks to collide against each other.
Chemical weathering that causes rock to turn red in color.
What is oxidation
What is the difference between mechanical and chemical weathering?
Mechanical Weathering breaks down the rock into smaller pieces.
Chemical Weathering breaks down the rock with chemical compound.
