Front

What is Chemical Weathering?

Back

Chemical Weathering involves the chemical alteration of minerals in rocks, often caused by water, acids, or gases.

Front

What is an example of Mechanical Weathering?

Back

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

Front

What is an example of Chemical Weathering?

Back

An example of Chemical Weathering is acid rain reacting with limestone, causing it to dissolve.

Front

What is the role of gravity in Erosion?

Back

Gravity causes materials like soil and rocks to move downhill, leading to landslides and mudslides.

Front

What is Ice Wedging?

Back

Ice Wedging is a type of Mechanical Weathering where water seeps into cracks, freezes, and expands, breaking the rock.

Front

What is Acid Rain?

Back

Acid Rain is rain that has been made acidic by pollutants, which can cause Chemical Weathering.
