Science Weathering, Erosion, Deposition

Front

What is erosion?

Back

Erosion is the geologic process by which water, wind, ice, and gravity move pieces of rock or soil.

Front

What is deposition?

Back

Deposition is the process that creates or constructs deltas, alluvial fans, beaches, sand dunes, or moraines.

Front

What is a tsunami?

Back

A tsunami is a rapid change to Earth's surface caused by underwater earthquakes or volcanic eruptions.

Front

What is an earthquake?

Back

An earthquake is a rapid change to Earth's surface caused by the movement of tectonic plates.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces like water, wind, and temperature changes.

Front

What causes slow changes to Earth's surface?

Back

Slow changes to Earth's surface can be caused by processes like weathering and the freezing and unfreezing of water in rock cracks.

Front

What is an example of a rapid change to Earth's surface?

Back

An example of a rapid change is a volcanic eruption.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of rock or soil, while weathering is the breaking down of rocks without movement.

Front

What are alluvial fans?

Back

Alluvial fans are landforms created by the deposition of sediment from flowing water.

Front

What are sand dunes?

Back

Sand dunes are hills of sand formed by the wind's deposition of sand.
