Front

What are the natural systems that cause Earth's surface to change?

Back

Gravity, living organisms, water, wind, ice, and atmosphere.

Front

Back

To manage our impact on the environment.

Front

What is the main cause of earthquakes?

Back

Faults in the Earth's crust.

Front

What is chemical weathering?

Back

The process where rocks undergo a chemical change, such as a metal statue turning green due to oxidation.

Front

What is physical weathering?

Back

The breaking of rocks into smaller pieces without changing their chemical composition.

Front

What role does gravity play in shaping Earth's surface?

Back

Gravity pulls materials down slopes, contributing to erosion and sediment transport.

Front

How does water contribute to changes in Earth's surface?

Back

Water causes erosion, transports sediments, and shapes landforms through processes like runoff and river flow.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken materials.

Front

What is the impact of living organisms on Earth's surface?

Back

Living organisms can contribute to soil formation, erosion, and the alteration of landscapes.

Front

How do glaciers affect the Earth's surface?

Back

Glaciers carve out valleys and shape mountains through the process of glacial erosion.
