Study Notes
Igneous Rocks
- Igneous rocks are formed when molten lava or magma cools down.
- Extrusive igneous rocks are formed on the Earth’s surface.
- Intrusive igneous rocks are formed beneath the Earth’s surface.
- Magma that cools slowly often has large-sized crystals.
- Magma that cools quickly often has small-sized crystals.
- Granite and basalt are examples of igneous rocks.
Metamorphic Rocks
- Metamorphic rocks are formed when existing rocks are changed by heat and/or pressure beneath the Earth's surface.
- Marble and slate are examples of metamorphic rocks.
- The original rock’s minerals may have different colours and also often have bands or layers when transformed into metamorphic rocks.
- Schist often shows layered bands.
- Gneiss has different coloured bands/layers.
- Increased heat and pressure make rocks stronger.
- Metamorphic rocks have different properties from the parent rock.
