Sedimentary rock and fossils fuels

Front

What is cementation?

Back

Cementation is the process where sediments stick together due to the crystallization of dissolved minerals, forming sedimentary rock.

Front

What is compaction?

Back

Compaction is the process of putting pressure on sediments underground, causing them to become denser and form sedimentary rock.

Front

Where does organic material in sedimentary rock come from?

Back

Organic material in sedimentary rock comes from animals and plants that perished long ago.

Front

What is the first step in the formation of fossil fuels?

Back

The first step is when plants and animals die.

Front

What happens after plants and animals die in the formation of fossil fuels?

Back

After they die, layers of sediment are deposited over them.

Front

What role does pressure play in the formation of fossil fuels?

Back

Pressure helps to compress the layers of sediment and organic material, contributing to the formation of fossil fuels.

Front

What is the significance of heat in the formation of fossil fuels?

Back

Heat helps to break down the organic material, transforming it into fossil fuels over time.

Front

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

Back

The correct order is: plants and animals die, layers of sediment are deposited, pressure and heat are applied, and then coal, oil, or natural gas is formed.

Front

What is erosion?

Back

Erosion is the process of wearing away rocks and soil by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations after being transported by wind, water, or ice.
