What two gemstones are sometimes found in metamorphic rocks

• Rose quartz

• Garnet

• Diamond

• Emerald

What two types of metamorphic rocks can slate turn into?

• Schist

• Basalt

• Shale

• Gneiss

What layer of the Earth do metamorphic rocks form in?

• Crust

• Mantle

• Inner Core

• Outer core

What two processes are involved in forming metamorphic rocks?

• Location

• Heat

• Water removal

• Pressure

• Mineral composition

What three changes can occur in rocks as the metamorphose?

• Water is squeezed out of the rock.

• Crystals can melt and then reform into crystals of new minerals (recrystallisation).

• Rocks can become more brittle.

• Crystals can grow into flattened sheets.

• Bands of different minerals form when crystals are squashed flat by forces in the Earth while they are hot.
