What is a volcano? How is it formed? How does it affect the earth's surface? As you read this you would not only answer these questions, but form new questions and ideas.

What is a volcano?

A volcano is a mountain that opens downward to a pool of molten rock. When the pressure builds up in a volcano, an eruption occurs. The gases and ash shoots up through the opening, and spill over the air with lava flow over the air with lava ash. The eruption can cause a mud slider, avalanches, falling ash, and even floods. It can even trigger a tsunami. But do they have hazards? If they do what are they? We'll be answering this soon.

How are they formed?

Volcanoes are formed when magma from the upper mantel works its way up to find a week spot in the crust or surface. Then the magma will soon be lava, and it would grow over time. But how are underwater volcanoes formed? Underwater volcanoes are form like the ones in the surface. They form from magma and they grow, but underwater volcanoes will keep on growing until they are island. Most of the land was made from volcanoes. But what are the stages of a volcano?

What are the different kinds of volcanoes?

There are four kinds of volcanoes. One is called the shield volcano which is a volcano that kind of have a shape of a shield, but that only means much more damage. Another is a strato which is the pointy ones, cinder cones, and splatter cones. Now lets answer the last question.

What are the stages of a volcano?

There are three stages. Which are an active volcano, which mean it will going to erupt soon. A dormant volcano, it's not going to erupt now, but someday in the future. And a extinct volcano, which means it's never going to erupt ever again. so lets answer the one question we haven't answered yet.

What are the hazards?

There're five hazards of a volcano. The first is lahar. Lahar is rapidly flowing mixture of volcanic debris and water. The other is pyroclastic flow. A pyroclastic flow is a fast moving body of hot gases and solids. Lava flow is the most powerful. It can be released from either a quiet or explosive eruption.
