RocksThere are 3 rock types:
- Sedimentary
- Igneous
- Metamorphic
-All 3 types can be found in Canada

Sedimentary RockSedimentary Rock: Rock usually formed in layers from the compression of sediments over millions of years.
Sediment: eroded material that is deposited by water, wind, or glacial ice.
Types of Sedimentary Rock:
- Limestone - Sandstone - Shale

Igneous RockIgneous Rock: rock formed from cooling molten rock (magma or lava). There are two types, intrusive and extrusive.
Intrusive: formed from magma that cools and solidifies within the earth. The magma cools very slowly which results in coarse crystals.
Extrusive: formed at the Earth's surface. The magma cools very quickly, so the crystals are much finer.
Types of Igneous Rock:
-Granite (intrusive) - Basalt (extrusive)

Metamorphic Rock
•
Metamorphic Rock: Type of rock formed when sedimentary and igneous rocks are subject to great heat and pressure.
Metamorphism: the solid state re-crystallization of pre-existing rocks due to changes in heat and/or pressure and/or introduction of fluids (i.e without melting).
Types of Metamorphic Rock:
- Marble - Slate
