Sedimentary rock and fossils fuels

Front

What are sedimentary rocks formed by?

Back

Sedimentary rocks are formed by compacting and cementing sediments.

Front

What is the correct order of the formation of fossil fuels?

Back

Plants and animals die, layers of sediment are deposited, pressure and heat are applied over time, resulting in coal, oil, or natural gas.

Front

What is cementation?

Back

Cementation is the process in which dissolved minerals crystallize and glue sediment together.

Front

Which of the following is NOT a quick change to the Earth's surface?

Back

Weathering is not a quick change; it is a slow process.

Front

What happens during deposition?

Back

Deposition is the process where sediment is dropped off in a pile.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient living organisms.

Front

How do sedimentary rocks differ from igneous rocks?

Back

Sedimentary rocks are formed from sediments, while igneous rocks are formed from the cooling of lava or magma.

Front

What role do pressure and heat play in the formation of fossil fuels?

Back

Pressure and heat transform organic material into fossil fuels over millions of years.

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural forces.

Front

What is the significance of sediment layers?

Back

Sediment layers can provide information about Earth's history and past environments.
