Weathering
The 2 types of weathering
Chemical weathering and physical weathering
Is erosion typically a constructive or destructive process?
constructive
What is deposition?
the placement/settling (final drop-off) of sediments
Which is NOT a cause of physical weathering?
A.) A mole burrows underground.
B.) A plant grows in a rock's crevice.

What does erosion do?
Erosion removes and transports the sediments that weathering created.
Physical
The two processes responsible for CONSTRUCTING new landforms are ________ and ________.
The interconnected process responsible for transforming rocks is known as the _______ ________.
Rock cycle
Name 2 types of chemical weathering.
acid rain and oxidation
Name 2 factors that could expedite the process of erosion.
steep slopes, lack of vegetation, water, wind
Name 2 depositional environments

Water is important to chemical weathering because most substances ________ in water.
dissolve
What two factors increase as we approach the interior of the Earth?
Heat and pressure
How does weathering differ from erosion?
Weathering breaks rocks, and erosion moves them
