Welcome to our page! We will be teaching you about volcanoes. Our website will be showing photos of volcanoes, and we also will show facts about them. We hope you learn something about volcanoes, and we hope you enjoy the website!
5 facts about volcanoes:
- The word volcano originally comes from the name of a Roman God of fire, Vulcan.
- There are volcanoes found on ocean floor and icecaps.
- Volcanic eruptions can send ash high into the air, over 30km.
- The tallest volcano in the Solar System isn't on Earth.
- About 20% of all volcanoes are under water.

Glossary:
Volcano: A weak spot in the crust where magma comes to the surface.
Ring of Fire: A major belt of volcanoes that rims the Pacific Ocean.
Magma: The molten mixture of rock-forming substances, gases, and water from the mantle.
Lava: Liquid magma that reaches the surface.
Composite Volcano: A tall, cone-shaped mountain in which layers of lava alternate with layers of ash and other volcanic materials.
Cinder Cone Volcano: A steep, cone-shaped hill or mountain made of volcanic ash, cinders, and bombs piled around a volcano's opening.
Shield Volcano: A wide, gently-sloping mountain made of layers of lava and formed by quiet eruptions.
Hot Spot: An area where magma from deep within the mantle melts through the crust above it.
Island Arc: As string of islands formed by the volcanoes along a deep ocean trench.
Caldera: The large hole at the top of a volcano formed when the volcano's magma chamber collapses.
Dike: A slab of volcanic rock formed when magma hardens in a vertical crack.
Sill: A slab of volcanic rock formed when magma hardens in a horizontal crack.
Batholith: A mass of rock formed when a large body of magma cooled inside the crust.
Lava Plateau: A flat wide surface, formed by the large outpourings of fluid lava from long narrow openings in the crust.
