Study Notes
Igneous Rock Formation
- Igneous rocks form from the cooling and solidification of magma or lava.
- Lava is molten rock that reaches the Earth's surface, typically through volcanic eruptions.
Factors Affecting Rock Formation
- The type of rock that forms as minerals cool and crystallize is determined by the chemical composition of the magma and the cooling rate.
Intrusive Igneous Rocks
- Intrusive igneous rocks are formed when magma cools and solidifies beneath the Earth’s surface.
- These rocks typically have a coarse-grained texture due to slow cooling, allowing larger crystals to form.
Crystal Size in Intrusive Igneous Rocks
- The size of crystals in intrusive igneous rocks increases when the cooling process is slow, giving them time to grow larger before solidifying.
