Min’s backyard has pieces of slate rock that are used as a footpath. Slate is a metamorphic rock that splits into flat pieces. What natural forces in Earth cause the formation of slate?

• Molten magma deep inside Earth cools and slowly hardens over time.

• Great heat and pressure cause the minerals to line up in parallel layers

• Lava erupts and runs down the side of a volcano, then cools and hardens.

• Sediments of once living things are deposited over time and become cemented.
