A volcano can be described as a hole in the earth’s crust that opens to the surface. During a volcanic eruption, molten rock, ash, cinders, gas, steam, and other lumps of rock hurls into the air through that opening.
Causes and Effect of Volcano Eruption in Iceland
During the recent Iceland volcanic activity, an opening through the earth crust led hurled rocks, ash, cinders, gas, and lumps of rocks, lava, and others into the atmosphere which came with devastating effects (Fema). Volcanoes mainly occur at the weak points in the earth’s crust. There are weak points at the boundaries of the plates and beneath the sea bed referred to as hot spots at which volcanic eruption are likely to occur.
Deep within the earth crust, there is build up of energy due to plate formation activities and when there is an opening on the earth surface, this energy pushes volcanic materials above the ground. Volcanic activities result from powerful forces of nature and they have many beneficial and destructive effects on earth, as was learned from the recent Iceland volcanic activities.
