What are fossil fuels?

Back

Fossil fuels are natural resources formed from the remains of dead plants and animals over millions of years. They include coal, oil, and natural gas.

Front

Why are fossil fuels considered non-renewable?

Back

Fossil fuels are considered non-renewable because they take millions of years to form, and once they are used up, they cannot be replaced within a human timescale.

Front

What is the main process that forms fossil fuels?

Back

Fossil fuels are formed through a process called decomposition, where heat and pressure transform organic material into coal, oil, or natural gas.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and other materials on Earth's surface into smaller pieces.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

What causes the seasons on Earth?

Back

The seasons are caused by the tilt of the Earth's axis and its orbit around the Sun, which affects the angle and intensity of sunlight received.

Front

How does the Earth's rotation affect day and night?

Back

The Earth's rotation on its axis causes day and night; as the Earth spins, different parts face the Sun or move into the shadow.

Front

What is the Grand Canyon an example of?

Back

The Grand Canyon is an example of erosion, where the Colorado River has worn away rock over millions of years to create the canyon.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces to a new location.
