What is the process called when layers of rock start to bind together under pressure?

• Erosion

• Compaction

• Cementation

• Weathering

What is lithification in the context of rock formation?

• The breaking down of rocks

• The combination of compaction and cementation

• The deposition of materials

• The erosion of rocks

What happens to the layers of rock and dirt during compaction?

• They are pressed together and become denser

• They are transported by water

• They break down into smaller pieces

• They are heated and melted

Which type of fossil fuel is primarily formed from plant matter in swamps?

• Natural gas

• Petroleum

• Peat

• Coal

How are fossil fuels like coal, petroleum, and natural gas formed?

• Through rapid heating of minerals

• By volcanic activity

• From decaying organic matter under pressure and heat

• By extraction from ocean beds
