Rock Cycle Quiz

What is the rock cycle?

• A model showing processes that turn other materials into rocks or change rock forms

• A process that relates each type of rock to one another

• A cycle that only involves the formation of igneous rocks

• A theory about the unchanging nature of rocks over time

Why is the rock cycle important?

• It is valuable in studying the history of the Earth

• It provides further evidence of the conservation of matter

• It explains the origin of the Earth's magnetic field

• It predicts the movement of tectonic plates

Which of the following are the three main types of rocks?

• Metamorphic, Sedimentary, Igneous

• Basalt, Granite, Marble

• Quartz, Diamond, Gold

• Slate, Limestone, Coal

Where does the energy that powers the rock cycle come from?

• The Sun's solar energy

• Thermal energy in Earth's hot interior

• Kinetic energy from the Earth's rotation

• Chemical energy from ocean currents

Metamorphic rocks are formed under which of the following conditions?

• Exposure to the atmosphere

What is the main process involved in the formation of sedimentary rocks?

• Melting and solidification

• Compaction and cementation

• Heat and pressure

• Erosion and deposition

Which type of sedimentary rock is formed by the accumulation of animal or plant debris?

• Clastic (Sandstone)

• Chemical (limestone)

• Organic (Coal)

• Metamorphic

What are sediments?

• Volcanic ash ejected during eruptions

• Parts of rocks, minerals, and organic matter that are broken away and deposited in a new location

• Crystals formed from cooling magma

• Fossils of ancient organisms found in rocks

Which of the following is a chemical sedimentary rock?
