Volcanoes

Volcanoes are a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.


Conical means in the shape of a cone!



So, can a mountain become a volcano? Watch this video for an explanation!




Volcanoes are classified as active, dormant or extinct.

This refers to the amount of volcanic activity. “Active” means there’s regular activity, “dormant” means there’s been recent activity but the volcano is currently quiet, and “extinct” means it’s been so long since the last eruption that it’s unlikely to ever erupt again.


Magma and lava are two different things!

Magma is the name given to hot liquid rock inside a volcano. Once it leaves the volcano, it’s known as lava.


Here are the parts of a volcano. Draw your own and label if you'd like!




Volcanoes exist throughout the solar system!

Other planets and moons have volcanoes, too! The largest volcano in our solar system is Olympus Mons, found on Mars.


There are hundreds of volcanoes around the globe. There are some in Hawaii, Costa Rica, Indonesia, and many more places around the world. Can you research where else there are volcanoes?


Try this experiment at home!

You can even make a volcano out of cardboard and place the cup in the middle to make it resemble a volcano even more!
