How do rivers shape the land?

Back

Rivers shape the land by eroding the soil and rocks along their banks, creating valleys and riverbeds.

Front

What role does ice play in weathering?

Back

Ice can cause weathering by freezing in cracks of rocks, expanding, and breaking the rocks apart.

Front

What is the main agent of erosion?

Back

Water is the main agent of erosion, as it can carry away soil and rocks through rivers, rain, and waves.

Front

What is the effect of sunlight on rocks?

Back

Sunlight can cause rocks to expand and contract, leading to cracks and weathering over time.

Front

What are tree roots' role in weathering?

Back

Tree roots can grow into cracks in rocks, and as they grow, they can break the rocks apart, causing weathering.

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.

Front

What can cause erosion besides water?

Back

Wind and ice can also cause erosion by moving soil and rocks from one place to another.
