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

Sorry, that’s Incorrect !

Igneous rock is formed by

cooling & hardening. It is intrusive because magma cooled beneath the Earth’s surface.
