Unit 4 Science Review

Front

What is a canyon?

Back

A canyon is a deep valley with steep sides, often formed by the erosion of rock by a river over a long period of time.

Front

How are U-shaped valleys formed?

Back

U-shaped valleys are formed by the movement of glaciers that carve out the landscape as they advance.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of dead plants and animals, used as energy sources, including coal, oil, and natural gas.

Front

Are fossil fuels renewable resources?

Back

No, fossil fuels are not renewable resources; they take millions of years to form and cannot be replenished within a human lifetime.

Front

What forms when dead animals are buried under sediment for millions of years?

Back

Oil forms when dead animals are buried under sediment for millions of years.

What forms when dead plants are buried under sediment for millions of years?

Back

Coal forms when dead plants are buried under sediment for millions of years.

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock that is formed by the accumulation and compaction of mineral and organic particles.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished naturally in a short period of time, while non-renewable resources, like fossil fuels, take millions of years to form.

Front

What role do glaciers play in shaping the landscape?

Back

Glaciers shape the landscape by eroding rock and soil, creating features like valleys, lakes, and fjords.

Front

What is the process of erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.
