- In science, I am learning about volcanoes. Which is very cool.
- Wow! That is cool. I want to learn about volcanoes too.
- Did you hear that an volcano has erupted? Just follow me.
- Really? Where?
- Magma is the name given to melted liquid rock below Earth's surface. It is stored below the volcano in a chamber or reservoir. During active periods, this reservoir fills with magma. After a large eruption, or during dormancy, this reservoir can drain, which may trigger the creation of a caldera.
- Wow! The Magma Chamber is so cool!
- Magma Chamber
- The magma conduit is the plumbing system of the volcano. Molten magma creates "pipes", through the volcano. Magma then travels through them to the surface
- So that's how magma goes through and goes to the surface.
- Magma Conduit
- The main vent often is located at or near the summit of the volcano. This is where most eruptive activity (lava flows, pyroclastic flows, and large gas emissions) occurs.
- Wow! I actually did not know that.
- Main Vent
- Lava flows occur during some eruptions. Once magma reaches the vent and flows onto the surface of Earth it is called lava. Lava flows add land to the surface, and build the mountains we call volcanoes. The island of Hawaii is nearly 100% cooled and solidified lava!
- Wow! I actually did not know that.
- Lava Flow
