Volcanoes

by: Chandler Beasley

What is a volcano?

A volcano is a mountain or hill, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earths crust.

What happens during a volcano eruption?

When magma reaches the earth's surface its called lava. It may pour out into gentle streams or erupt violently into the air. Rocks that are torn apart from gas may be shot into the air with the lava.

Why are volcanoes dangerous to us?

When has this geohazard hurt the environment?

  • It was 1803 in Indonesia, 102,000 people died by the eruption of Mount Tambora.

Ways to protect yourself from volcanoes

  • Use goggles instead of contact lenses.
  • Use a dust mask or hold a damp cloth over your face to help with breathing.
  • Stay away from areas downwind from the volcano to avoid volcanic ash.
  • Stay indoors until the ash has settled unless there is a danger of the roof collapsing.
