Understanding the Rock Cycle

What is the rock cycle primarily about?

• The formation of volcanoes

• The erosion of mountains

• The transformation of rocks in the Earth's crust

• The cooling of the Earth's core

What can sedimentary rock transform into under heat and pressure?

• Igneous rock

• Granite

• Metamorphic rock

• Limestone

What forces can cause metamorphic rock to break down into tiny pieces?

• Volcanic activity and erosion

• Chemical reactions

• Tectonic movements

• Solar radiation

What happens to the tiny pieces of rock after they break down?

• They dissolve into minerals

• They form new sedimentary rock

• They become magma

• They evaporate

What is the nature of the rock cycle as described in the text?

• A rare occurrence

• A quick transformation

• A never-ending story

• A temporary process
