Changes to Earth's Surface

Front

What is necessary for sand dunes to form?

Back

Loose sand and strong wind.

Front

What is the primary cause of slow change like a canyon forming?

Back

Erosion from water.

Front

What is a delta?

Back

A landform that forms at the mouth of a river where it meets a body of water, created by the deposition of sediment.

Front

How does a delta form?

When a river slows down and drops sediments as it meets the ocean or a lake.

Front

What is erosion?

Back

The process by which natural forces like water, wind, or ice move soil and rock from one location to another.

Front

What is deposition?

Back

The process by which sediments are laid down in new locations after being transported by wind, water, or ice.

Front

What role does wind play in shaping the Earth's surface?

Back

Wind can erode and transport sediments, leading to the formation of features like sand dunes.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of materials, while weathering is the breaking down of rocks without movement.

Front

What is a canyon?

Back

A deep valley with steep sides, often formed by the erosion of a river over a long period.

Front

What is sediment?

Back

Small particles of rock and soil that are transported by wind, water, or ice.
