5th Grade Unit 4 Earth Changes

Front

What is wind erosion?

Back

Wind erosion is the process by which wind removes soil and rock from one location and transports it to another, often creating features like sand dunes.

Front

How do organisms contribute to erosion?

Back

Organisms, such as burrowing animals, break up soil when they search for food or create homes, which can lead to erosion.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces, called sediment, through natural forces like wind, water, and chemicals.

Front

What are the two main types of weathering?

Back

The two main types of weathering are mechanical weathering (physical breakdown of rocks) and chemical weathering (breakdown of rocks through chemical reactions).

Front

How can chemical weathering be prevented?

Back

Chemical weathering can be prevented by washing and protecting surfaces regularly to reduce exposure to harmful substances.

Front

What is a destructive force in geology?

Back

A destructive force is a natural process that breaks down or removes material from the Earth's surface, such as earthquakes and erosion.

Front

What is a constructive force in geology?

Back

A constructive force is a natural process that builds up or creates new landforms, such as volcanic eruptions and sediment deposition.

Front

What role do plants play in preventing erosion?

Back

Plants help prevent erosion by holding soil together with their roots and absorbing excess water, which stabilizes the ground.

Front

What is a landslide?

Back

A landslide is the sudden and fast movement of a large amount of earth material down a slope, often triggered by heavy rain or earthquakes.

Front

What is a seismograph?

Back

A seismograph is an instrument used to detect and record the intensity and duration of earthquakes.
