Front

What are fossil fuels?

Back

Fossil fuels are natural resources like coal, oil, and natural gas that come from the remains of dead plants and animals.

Front

Why are fossil fuels considered non-renewable?

Front

What is erosion?

Back

Erosion is the movement of sediment and soil from one place to another, often caused by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where earth materials are deposited in a new location after being transported by erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion involves the movement of those pieces to a new location.

Front

What role does the Sun play in the water cycle?

Back

The Sun provides energy that causes evaporation, turning water from lakes and rivers into vapor, which then forms clouds.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through processes like weathering, erosion, and sedimentation.
