Exploring the Rock Cycle and Types of Rock

What are the three main types of rocks mentioned?

• Basalt, Granite, Marble

• Slate, Quartzite, Gneiss

• Coal, Diamond, Opal

• Igneous, Sedimentary, Metamorphic

How does igneous rock form?

• All of the above

• From heat and pressure on existing rocks

• From sediment under pressure

• From magma cooling and solidifying
