What is a rock?

• A type of plant

• A natural, solid mixture of minerals or grains

• A kind of animal

• A liquid substance

What are the three major types of rocks?

• Igneous, Sedimentary, Metamorphic

• Igneous, Metamorphic, Metallic

• Sedimentary, Metallic, Igneous

• Metamorphic, Sedimentary, Organic

What is the series of natural processes that change one type of rock into another type of rock called?

• The Water Cycle

• The Rock Cycle

• The Carbon Cycle

• The Life Cycle

What drives the rock cycle?

• Forces on Earth's surface and deep within the Earth

• Only the heat from the sun

• The movement of ocean currents

• The rotation of the Earth

What process breaks down rock into sediment?

• Weathering and erosion by wind and water

• Melting by the sun

• Freezing by ice

• Growth of plants

What role does heat from Earth's interior play in the rock cycle?

• It melts and deforms rocks

• It cools and solidifies rocks

• It evaporates water

• It creates new landforms

What does pressure from Earth's interior do to sediments?

• Compacts and cements them back together

• Breaks them apart

• Turns them into gas

• Dissolves them in water

What process changes sediments into sedimentary rock in the rock cycle?

• Melting and cooling

• Compaction and cementation

• Freezing and thawing

• Evaporation and condensation

Through what process are igneous rocks changed to sediments in the rock cycle?

• By melting and cooling

• By weathering and erosion

• By freezing and thawing

• By compression and cementation

Through what process are metamorphic rocks changed to sediments in the rock cycle?

• By melting and cooling

• By weathering and erosion

• By freezing and thawing

• By evaporation and condensation
