A loop-like bend in the course of a river.

Front

What are soil horizons?

Back

Layers of soil that differ in composition, texture, and color, typically including topsoil, subsoil, and parent material.

Front

What role does gravity play in erosion?

Back

Gravity causes materials to move downhill, contributing to erosion through processes like landslides and rockfalls.

Front

How do streams contribute to erosion?

Back

Streams erode their banks and beds, transporting sediment downstream and reshaping the landscape.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those materials.

Front

What is abrasion in the context of erosion?

Back

The process of scraping or wearing away of rock surfaces by friction from particles carried by wind, water, or ice.
