Weathering, Erosion, and Deposition

Front

What is mechanical weathering?

Back

The natural breakdown of rock into sediments by physical changes

Front

What are the common causes of mechanical weathering?

Back

Ice wedging, root growth, and impacts

Front

Exfoliation

Back

The peeling off of thin layers of rock from exposed surfaces

Front

What are some agents of mechanical weathering?

Back

Ice wedging, root growth, and impacts

Front

Chemical weathering

Back

The process of rocks absorbing water and reacting with their molecules

Front

What are some chemical reactions that cause chemical weathering?

Back

Hydration, carbonation, and hydrolysis

Front

How does water contribute to chemical weathering?

Back

By dissolving certain rocks and minerals

Front

What factors determine the rate of weathering?

Back

The composition of the rock, the rock's surface area, and climate conditions

Front

Differential weathering

Back

The uneven weathering of different rocks in the same landform

Front

Why do rocks with a greater surface-area-to-volume ratio change faster?

Back

Because they are more exposed to air and water
