• The surface of the earth is floating on magma. 
• The earths surface is flexible. 
• When the surface is stretched a lot you get a earthquake.
• Lava comes out for the same kind of rock which we see but it's under the earths surface and lava makes it hot and you can rip brake easily inside.
• The earths surface is on top of the lava(magma).
• Heat makes the plates move.
• When plates scratch or touch each other they create mountains.
• Lava comes out of some kind of liquid and then it freezes.
• Epicenter is a the point on the Earth's surface directly above the focus of an earthquake

3 types of boundaries

1. Convergent boundaries(compression)
2. Divergent boundaries(tension)
3. Transform boundaries(shearing)
