In this lesson you will use the Internet to research information on volcanoes and then write a report on your results.
A volcano is a location where magma, or hot melted rock from within
a planet, reaches the surface.
It may happen violently, in a massive supersonic explosion, or more quietly, as a sticky, slow lava flow.
Volcanoes have been a part of earth's history long before humans.
Compare the history of human beings, a few million years in the making, to that of the Earth, over four billion years in the making.
