This is a Volcano. Volcanos are very cool but they can also be very scary. The rocks on the mountain can give us crystals.

When a volcano erupts a cloud will release but not just any cloud. An ash cloud with ash and dust. After the ash cloud is settled the lava will come out.

The lava is coming out of the volcano. The lava does not move very fast because it will not have a lot to grip on to.

This is a diagram of how volcanoes form. Volcanos form when an opening in the Earth’s crust the molten rock, hardened rock, and gasses will form a volcano.

Now to talk about earthquakes!

YAY!

This is an earthquake diagram. The Epicenter is right above the focus.

Tsunami (sue-Nah-me) happens when large earthquakes occur near or in the ocean. When this happens a large wave will move until it finds a place to stop.

This is a machine called a Seismometer( size-mom-meter). They can detect earthquakes all around the world.
