What is a Volcano?

Volcanoes are often known as openings in the Earth's surface, allowing molten rock, ash and gases to come up from beneath the surface. Over a long period of time, or series of eruptions, a large hill or mountain will develop. Volcanoes usually occur along two tectonic plates, which constantly grind against each other, causing weak spots on the Earth's surface and making it easier for magma to flow through.

This is a good start. Now I want you to express original ideas on your subject, post more to this blog, increase your content on the subject of volcanoes, post comments on other community's (student) websites, and add photographs and animation to your blogsite.

What, in celsius, is 2012 Fahrenheit?
