What is a Volcano?




Volcano's is a mountain topped with vents, holes, and craters. When the volcano erupts, lava, ash, cinders, dust, and hot gas can pour out the top. Magma (when it's deep in the ground) or lava (when it reaches the earth's surface) is very hot, liquid rock. When the lava cools down, it turns into hard rock. Ash is a gray powder that results from material being burned in the volcano. Ash can be carried in the air for many miles.Volcanoes occur along the earth's tectonic plates where molten rock is forced upward from magma reservoirs deep in the earth. The magma may be fifty to one hundred miles below the ground. As the magma rises, it gives off gases that cause an explosion in the vents of the volcano. Lava can reach temperatures of over 2000 degrees F. Molten rock, dust, and gases push through the opening in the earth's crust and form a mountain. A violent explosion can cause the top of the volcano to blow off leaving a deep crater.There are four types of volcanoes: active, intermittent, dormant, and extinct. Volcanoes can occur on land or in the water. (http://42explore.com/volcano.htm)
