- Volcano Eruption
- We're magma, molten rocks.
- Hooray! Let's explore the world!
- Igneous Rock Formation
- We're intrusive igneous rocks.
- We're cooling and become extrusive igneous rocks.
- Weathering, Erosion, and Deposition
- When the tectonic plates move, they can cause the volcano to erupt. The hot magma from below rises up to the surface.
- Sedimentary Rock Formation
- Igneous rocks form from cooling lava and magma. When lava cools on Earth's surface is called extrusive igneous rock. When magma cools beneath Earth's surface is called intrusive igneous rock.
- Temperature and Pressure Change
- When extrusive igneous rocks are exposed at Earth's surface, they may break down into sediments by weathering, erosion, and deposition.
- Metamorphic Rock Formation
- We're metamorphic rocks now!
- After weathering, we're sediments now!
- When sediments are pressed together and cemented, the sediments become sedimentary rocks.
- We deposit, compact, and cement together here.
- Now we turn into sedimentary rocks.
- Under certain temperature and pressure conditions, the intrusive igneous rocks may change directly into metamorphic rocks while still beneath Earth's surface.
- So hot in here! We're burning!
- Over millions of years, the solid rocks change, and new crytals are formed.
- Some of us grow crystals and become diamonds!
