Volcanic eruptions


Mark Leonard

A volcano is an opening in the earth's crust through which magma, gases and ash are released to the earth's surface. The molten rock material found in the interior of the earth is called magma. It can be noted that when magma reaches the earth’s surface, it is known as lava. Vent is an opening or mouth of a volcano. Fumaroles are the gushing fumes through the gap in the volcano. Volcanic ash consists of fragments of pulverized rock, minerals and volcanic glass, created during volcanic eruptions.
