Volcanoes

Volcanoes are a well known aspect of life. Some people think of them as natural disasters, others as beautiful wonders, but whatever you think about them, there is a lot that people do not understand. This slide will assist your learning about these incredible mountains.

How are volcanoes formed?

A volcano is actually a mountain. It is formed when hot magma from the Earth's mantle finds its way to the Earth's surface. It eventually finds its way up through the top of a mountain, literally blowing the top off. Dust and ash ride into the air, along with lava (the term used to describe magma outside of the volcano.)

How do volcanoes impact on everyday life?

Volcanoes can change the lives of innocent citizents in drastic measures. Homes destroyed, lives taken, villages burned, volcanoes aren't only beautiful, but deadly.

For example, Mount Vesuvious errupted in 79 AD, burying the whole of Pompeii in ash, rubble, and molten lava. Everybody died, except the lucky few visiting families, out of the area.

Bodies, perfectly presereved, were discovered in the rubble, and they show the images of horror and utter terror portrayed on the faces of the victims. It is a disturbing sight, but proves the tragedy a volcano erruption can be.

However, not all volcanoes are viewed as life-threatening dangers. Some are considered as natural beauties; wonders of the Earth. This next page will show you the other side of these mysteries.
