What is a Volcano?

• A volcano is a mountain or rock which has a gap in it. Because there was too much pressure underground, the rock or mountain would have lava come out of the gap. Lava is called magma underneath ground but called lava above ground.

A famous volcano

• Have you heard of Mt Vesuvius?

Some of you might have. Mt Vesuvius is a volcano which covered (or buried) Pompeii. It is a composite volcano. A composite volcano is a volcano which spits both lava and ashes.

Mt Vesuvius

What has Volcanoes affected?

• Mt. Vesuvius has affected Pompeii, Stabiae and Herculaneum by burying them.

• Mt. Fuji has affected people because now they can’t climb Mt. Fuji.

• Mt. St Helens changed the lives of thousands and transformed thousands of acres of trees into total waste.

Another semi-famous volcano

• You might of heard of Mt. Fuji, the highest mountain in Japan? Imagine if you were on top of Mt. Fuji when the mountain began to shake and suddenly lava came up. Would that be scary?

The Ring of Fire

• You may or may not have heard of the Ring of Fire. The Ring of Fire is in Hawaii and consists of at least 100 volcanoes. Some of them are extinct. Nearly all of Hawaii is made out of volcanoes.

Did you know?

• There are 20 volcanoes which are still active now.• Volcanoes grow when the erupt.• The largest volcano isn’t on earth . It is in Mars. Scientists think that

the shield volcano Olympus Mons got so big because Mars doesn’t have tectonic plates.

• The tallest volcano on earth is Mauna Kea at 30,000 feet (9,100 m) in Hawaii. The largest volcano on earth is Mauna Loa.

• Mauna Kea is so high that it is taller than Mount Everest if you measure Mauna Kea from the Ocean floor.

• A cinder cone volcano is smaller than a shield volcano and a composite volcano.

• Name one volcano I have talked about.

• Where is Mount Fuji?

• Where is the Ring of Fire?

• What is the tallest mountain on Earth?

• Where is Olympus Mons?

• Does Mars have any Tectonic plates?
