PHY VS CHEMICAL WEATHERING

Front

What is weathering?

Back

The breaking down of Earth’s crust into smaller and smaller pieces.

Front

How do plants weather rocks?

Back

When roots grow into cracks of rocks and expand the rock.

Front

What is mechanical weathering?

Back

The physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

The process that changes the chemical composition of rocks, often through reactions with water, acids, or gases.

Front

What is ice wedging?

Back

A type of mechanical weathering where water freezes in cracks of rocks, expands, and breaks the rocks apart.

Front

How does freezing water cause weathering of rocks?

Back

Freezing water expands cracks and breaks rocks.

Front

What role does gravity play in weathering?

Back

Gravity can cause rocks and soil to move, leading to erosion and weathering.

Front

What is abrasion in the context of weathering?

Back

The process of rocks being worn down by friction and contact with other materials.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces by water, wind, or ice.

Front

What is the effect of acid rain on rocks?

Back

Acid rain can chemically weather rocks by dissolving minerals and altering their composition.
