5th Grade Unit 4 Earth Changes

Front

What is wind erosion?

Back

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

Front

How does wind erosion affect deserts?

Back

Wind erosion creates sand dunes in deserts.

Front

What is weathering?

Back

Weathering is a destructive force that breaks down rocks into smaller pieces called sediment, caused by wind, water, and chemicals.

Front

What can stop chemical weathering on cement surfaces?

Back

Washing and protecting the cement regularly can help stop chemical weathering.

Front

What is a seismograph?

Back

A seismograph is an instrument used by scientists to study and measure the intensity and duration of earthquakes.

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up the Earth's surface, such as volcanic eruptions and sediment deposition.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down or remove materials from the Earth's surface, such as erosion and earthquakes.

Front

How do organisms contribute to erosion?

Back

Some organisms break up soil when they search for food or burrow underground, which can lead to erosion.

Front

Why is vegetation important for soil stability?

Back

Vegetation helps hold soil together with roots, absorbs excess water, and prevents erosion and landslides.

Front

What happens in areas with little vegetation?

Back

Areas with little vegetation are more likely to experience erosion and landslides because there are no roots to hold the soil together.
