Chemical Weathering involves the chemical alteration of minerals in rocks, often resulting in new minerals.

Front

What is Erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

Give an example of Mechanical Weathering.

Back

An example of Mechanical Weathering is ice wedging, where water seeps into cracks, freezes, and expands, breaking the rock apart.

Front

What role does temperature play in Mechanical Weathering?

Back

Temperature changes can cause rocks to expand and contract, leading to fractures and breakdown.
