Information about Volcanoes

             Volcanoes!

What are Volcanoes?
A volcano is a mountain that opens  to a pool of molten rock. Gases and rock come out through the opening and spills all over. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches etc. Volcano eruptions can down knock down the entire forest. An erupting volcano can trigger tsunamis, flash floods, earthquakes etc.

How are volcanoes formed?
Volcanoes are formed because magma is  within the Earth's upper surface. At the surface, it can erupt to form lava flows and ash flows lickrish. Over time as the volcano continues to erupt, it will get bigger and bigger.

Types of volcanoes
Scientists have volcanoes to three main categories: active, dormant, and extinct. An active volcano is one which has  erupted and there is a possible way that it may erupt soon. A dormant volcano is one which has not erupted in a long time but it is a possibility it can erupt in the future. An extinct volcano is one which has erupted thousands of years ago and there’s no possibility of eruption ever again.
