Weathering and Erosion

Front

What is Weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces or minerals due to various factors like water, ice, and temperature changes.

Front

What is Erosion?

Back

Erosion is the movement of sediment and soil from one location to another, primarily caused by water, wind, ice, and gravity.

Front

What is an example of Erosion?

Back

Sand being pulled away from a beach by waves.

Front

How does freezing water cause the weathering of rocks?

Back

Freezing water expands in cracks of rocks, which can break the rocks apart.

Front

What natural process is largely responsible for the formation of the Grand Canyon?

Back

Water erosion over millions of years.

Front

What is Deposition?

Back

Deposition is the process where sediment settles out of the transporting medium, like water or wind, and accumulates in a new location.

Front

What role does gravity play in Erosion?

Back

Gravity pulls sediment downhill, contributing to erosion, especially in landslides and riverbanks.

Front

What is the difference between Weathering and Erosion?

Back

Weathering breaks down rocks in place, while erosion moves the broken pieces to new locations.

Front

What is a glacier?

Back

A glacier is a large mass of ice that moves slowly over land, causing erosion as it drags rocks and sediment with it.

Front

What is the Water Cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, which includes processes like evaporation, condensation, and precipitation.
