The Fun Formation of Volcanoes!

Here today I'm going to be telling about how volcanoes come to be. How they began, and their three different stages; active, dormant, and extinct.

Plates of the earth's crust slowly move apart. This allows the magma to rise to the surface. Due to the great change in temperature, the magma cools into rock. Although some of this magma that reaches the surface bursts out in an eruption into lava. This continues to happen, and slowly, over a very long period of time, the magma and lava that have hardened begin to build up to form a mountain. The most common form of mountain is the cone-shaped volcano. The more eruptions that happen, the higher the mountain gets to be. But sometimes in an extreme eruption, parts of the volcano near the crater can get blown off, causing some to have odd, uneven shapes.

One stage of a volcano is the active stage. This is when the volcano is still currently erupting, or is expected to erupt soon. These volcanoes are watched closely by the people who live near them, so that they know when they will have to moved to a safe place. An example of an active volcano is Colo, in Indonesia.

Another stage of volcanoes is the dormant stage. This is when the volcano has been erupting in times in the past, but has not erupted in quite a long time. These volcanoes are still expected to erupt at some point in the future. They are not classified as extinct yet. An example of a dormant volcano is Mt Baker in Washington, USA.

The last stage of a volcano is the extinct stage. This is when the volcano has not erupted in a very long amount of time, has not erupted in historical times, and is not ever expected to again. On few occasions a volcano classified as extinct may become active. An example of an extinct volcano is Kilimanjaro in Tanzania.

Well that's it for today on volcanoes, thanks for reading and keep posted.
