What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces such as water, ice, and temperature changes.

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one place to another by water, ice, wind, or gravity.

What forms when a river meets the ocean and slows down?

Back

A delta forms when a river meets the ocean and slows down, causing it to drop sediments.

What causes the deposition of sediments at a delta?

Back

The deposition of sediments at a delta is caused by river water slowing as it enters the ocean.

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, characterized by sediment deposits.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion moves those broken pieces to a different location.

Front

What role does gravity play in erosion?

Back

Gravity helps move weathered materials downhill, contributing to erosion.

What is an example of mechanical weathering?

Back

An example of mechanical weathering is when water freezes in rock cracks, expands, and breaks the rock apart.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is when acid rain reacts with minerals in rocks, changing their composition.
