Cause and Effect of Volcanoes Any natural opening in the Earth’s crust‚ called a fissure‚ where melted rock‚ ash‚ gases‚ and steam come out is called a volcano. Volcanoes look like mountains‚ but they are really flat land that is pushed upward because of the pressure below the earth. The pressure comes from hot magma and gases that build up below the earth’s surface and that work up to the surface through cracks in the earth’s plates. As it is forced up to the surface‚ the gases and magma push

With reference to various examples‚ discuss how ‘natural’ disasters are socially constructed. While natural disasters such as floods‚ drought and hurricanes are commonly thought to occur due to environmental forces such as weather‚ climate and tectonic movements; a deeper investigation into the ‘disaster’ displays other contributing forces. Human factors have a large‚ if not equal‚ contribution to the occurrance and outcome of such disasters (Pelling‚ 2001). As Pelling (2001) argues‚ there is
