* A shield volcano is formed from lava emission. Since lava is a fluid, it flows easily and travels far resulting in a wide base with a shallow slope.
When a volcano ejects so much sulfur dioxide and ash, they prevent the sunlight from reaching the earth's surface. It results in a decrease in temperature, not only within the volcanic area, but also around the world as winds carry the volcanic materials as they circulate.
* The heat from inside the Earth is collected in a geothermal power plant by drilling a hole in the ground at great depth. The heat is used to boil water to produce a steam that turns the turbine. The mechanical energy from the turbine is transferred to the generator which in turn, transforms the mechanical energy to electrical energy.
