Rock Cycle Quiz

What is the rock cycle?

• A system that turns all rocks into fossils

• A process that describes how rocks change from one type to another over time

• A way to recycle old rocks into new ones at factories

• A process that only happens underground

How is igneous rock formed?

• By heat and pressure deep inside the Earth

• By the cooling and solidification of magma or lava

• By the compression of small pieces of rock

• By erosion from wind and water

What process turns sediment into sedimentary rock?

• Melting and cooling

• Heat and pressure

• Weathering and erosion

• Compaction and cementation

What causes metamorphic rocks to form?

• Heat and pressure deep inside the Earth

• Cooling lava on the surface

• The breaking down of rocks by wind and water

• Layers of sediment building up over time

Which of these is an example of a sedimentary rock?

• Basalt

• Marble

• Sandstone

• Obsidian

What process breaks down rocks into smaller pieces?

• Melting

• Weathering

What happens to rocks when they are exposed to extreme heat and pressure?

• They turn into magma

• They become metamorphic rocks

• They break apart into sediments

• They cool and harden into igneous rock

How can sedimentary rock turn into igneous rock?

• By being heated and pressurized underground

• By melting into magma and then cooling

• By breaking down into sediments

• By being compacted and cemented

What is the process where rocks are carried away by wind or water?

• Erosion

• Melting

• Solidification

• Cementation

Which of the following is NOT a step in the rock cycle?
