The Rock Cycle
Metamorphic
Igneous
Sedimentary
Rock Types
Metamorphic
Formation:
Heat Pressure Crust movement Tons of rock Chemical changes
Ex: Marble
Increased temperatures deep below
Earth’s surface & pressure from the weight of rocks causes the rock to change form.
The chemicals experience a change allowing it to be squeezed into a different form.
Metamorphic
Metamorphic
Igneous
Formation:
Cooling Solidification Magma Lava Crystallization Intrusive & Extrusive
Ex: Obsidian
Formed when molten rock deep within the
Earth cools & becomes solid. If beneath surface: magma cools &
hardens Intrusive
If erupts through volcano: lava cools & hardens Extrusive
Igneous
Igneous
Sedimentary
Formation:
Sediment Weathering Erosion Compaction Cementation
Ex: Sandstone
Sediments are weathered or eroded,
then are transported elsewhere to be deposited into layers.
Compacted by the heavy layers piling up over time
Cemented by dissolved minerals filling the spaces between the sediments

How is metamorphic rock formed?
Click here to try again!
Sorry, that’s Incorrect !
Metamorphic rock is formed by
increased temperatures and pressures found beneath Earth’s surface.

Sorry, that’s Incorrect !
Igneous rock is formed by
cooling & hardening. It is intrusive because magma cooled beneath the Earth’s surface.
