Study Notes
Rock Formation and Metamorphism
- Rocks solidify below the ground or on the surface as lava.
- As rock cools, minerals form crystals with distinct shapes.
- Earth movements create pressure, and molten rock (magma) heats surrounding rocks.
- Metamorphic rocks form when igneous and sedimentary rocks are altered by heat and pressure.
- Lava is molten rock on the Earth's surface.
Volcanic Cones
- Many volcanoes are cone-shaped due to lava flowing from a central vent and solidifying.
- Volcanic explosions also contribute to cone formation.
- Molten rock ejected into the air solidifies into lumps or bombs before landing.
- Layers of solidified rock form a cone around the vent.
Metamorphic Process
- Sedimentary and igneous rocks transform into metamorphic rocks through heat and pressure.
