Volcanoes

Basics

A volcano is a mountain topped with vents, holes and craters. When the volcano erupts, lave, ash, cinder, dust and hot gasses can pour out the top. Magma (When its deep in the ground) or lave (When it reaches the earth's surface) is very hot liquid rock. When the lave cools down it turns to hard black rock. Ash is a gray material being burned in the volcano. Ash can be carried into the air for many miles.

Eruptions
Volcanoes occur along the earth's tectonic plates where molten rock is forced upward from magma reservoirs deep in the earth. The volcano may be 50 to 100 feet in the ground. As the heat rises over 2000 degrees F it explodes flying lava and ash into the air. And sometimes may cause craters flying.
