Rocks are made of

• 2 or more chemicals

• 2 or more minerals

This layer of the earth is liquid and is where magma comes from.

• core

• mantle

• crust

Metamorphic rocks are formed deep in earth's crust by

• volcanoes

• heat

• sediments

• pressure

When lava or magma cool down and harden it forms

• metamorphic rocks

• sedimentary rocks

• igneous rocks

When weathering happens to rocks they break down and eventually form

• minerals

• soil

• bedrock

• sand

These rocks are formed when little bits of rock get squished together and harden into layers.

• metamorphic rocks

• sedimentary rocks

• igneous rocks

When a rock is changed into a different type it is called a

• metamorphic rock

• sedimentary rock

• igneous rock

Rocks are sorted by

• what they look like

• where they are found

• how they are formed

• how much they cost

What are the 3 major types of rocks?

• Igneous, Metamorphic, Sedimentary
• Metamorphic, Igneous, Cementation
• Brown, Red, Gray
• Streak, Hardness, Breakage

Each rock type can follow only one pathway of the rock cycle.
