Exploring Rocks and the Rock Cycle

What are the three main types of rocks?

• Igneous, Metamorphic, and Sedimentary

• Igneous, Sedimentary, and Fossil

• Metamorphic, Fossil, and Mineral

How are sedimentary rocks primarily formed?

• By the cooling of magma

• By the accumulation and compaction of sediments

• By the transformation of existing rock under heat and pressure

• By volcanic eruptions
