Fast and Slow Changes to Earth

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered materials from one place to another, often caused by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped off in a new location, forming new landforms.

Front

Which natural forces cause weathering?

Back

Wind, water, ice, and temperature changes are natural forces that cause weathering.

Front

What is the main cause of earthquakes?

Back

Earthquakes are mainly caused by pressure from within the Earth's crust.

Front

What is a landslide?

Back

A landslide is the sudden movement of rock and soil down a slope, often triggered by heavy rain or earthquakes.

Front

How does ice cause weathering?

Back

Ice causes weathering by breaking rocks apart when it freezes and expands in cracks.

Front

What is the difference between fast and slow changes to the Earth?

Back

Fast changes occur quickly, like earthquakes and volcanic eruptions, while slow changes happen over a long time, like erosion and weathering.

Front

What role does water play in erosion?

Back

Water can carry away soil and rocks, leading to erosion, especially during heavy rains or floods.

Front

What is a volcano?

Back

A volcano is an opening in the Earth's surface where molten rock, ash, and gases can escape.
