Weathering and Erosion

Front

What is erosion?

Back

Erosion is the process by which water, ice, wind, or gravity moves fragments of rock and soil.

Front

What natural force primarily causes sand dunes to shift position?

Back

Wind is the primary natural force that causes sand dunes to shift position.

Front

What is the effect of flood waters on soil?

Back

Flood waters can cause erosion by moving soil from one location to another.

Front

How does wind contribute to erosion?

Back

Wind contributes to erosion by blowing sand and other particles from one location to another.

Front

What are the three main agents of erosion?

Back

The three main agents of erosion are water, ice, and wind.

Front

Define weathering in the context of erosion.

Back

Weathering is the process that breaks down rocks and minerals into smaller particles, which can then be transported by erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks and minerals, while erosion is the movement of those particles from one place to another.

Front

What role does gravity play in erosion?

Back

Gravity causes materials to move downhill, contributing to erosion, especially in landslides and rockfalls.

Front

How can human activities influence erosion?

Back

Human activities such as deforestation, construction, and agriculture can increase erosion by disturbing the soil and vegetation.

Front

What is sediment transport?

Back

Sediment transport is the movement of solid particles, such as sand and silt, by wind, water, or ice.
