Understanding the Rock Cycle

What is the primary process that forms igneous rocks?

• Erosion of existing rocks

• Cooling and solidification of magma

• Compression of sediments

• Transformation under heat and pressure

Which type of rock is most commonly found on the Earth's surface?

• Metamorphic rocks

• Igneous rocks

• Volcanic rocks

• Sedimentary rocks

How do sedimentary rocks typically form?

• Through the cooling of lava

• By the melting of existing rocks

• By the accumulation and cementation of sediments

• From the crystallization of minerals

What causes metamorphic rocks to change form?

• Erosion by wind and water

• Cooling of magma

• Heat and pressure

• Sedimentation

Which rock type can transform into another due to high temperature or pressure?

• Only metamorphic rocks

• Only sedimentary rocks

• Only igneous rocks

• All rock types

What is a key factor in the erosion process?

• The crystallization of minerals

• Weathering by water, temperature, and wind

• The movement of tectonic plates

• The presence of fossils

How does acid rain contribute to the rock cycle?

• By compressing sediments

• By forming new rocks

• By cooling magma

• By dissolving certain types of rocks

What role do tectonic plates play in the rock cycle?

• They only affect sedimentary rocks

• They have no impact on the rock cycle

• They prevent erosion

• They cause rocks to melt into magma

What happens when tectonic plates collide?

• They generate heat and cause rock recycling

• They create new sedimentary rocks

• They form new igneous rocks

• They have no effect on rocks

What is the significance of the rock cycle?

• It describes the continuous transformation of rocks

• It is only relevant to volcanic activity

• It is a static process with no changes

• It explains the formation of only igneous rocks
