How is electricity generated in volcanic areas?

Answer 1

Breaks in the tectonic plates that slowly move under us. This creates a hole that allows hot molten rock, ash and gases to escape. The build up of cooled molten rock and ash will cause the mountainous shape to occur, or when two plates collide the tall shape can occur as well.

Answer 2

• How to compare and contrast the particular advantages and disadvantages of using different energy sources to generate electricity.

• In most power stations an energy source is used to heat water.

• The steam produced drives a turbine which is coupled to an electrical generator.

• Common energy sources include coal, oil and gas, which are burnt to produce heat and uranium/plutonium, in which nuclear fission produces heat.

• Energy from renewable energy sources can be used to drive turbines directly.

• Renewable energy sources used in this way include wind, the rise and fall of water due to waves and tides, and the falling of water in hydroelectric schemes.

• Electricity can be produced directly from the Sun's radiation using solar cells.

• In some volcanic areas hot water and steam rise to the surface. The steam can be tapped and used to drive turbines. This is known as geothermal energy.

• Using different energy resources has different effects on the environment. These effects include the release of substances into the atmosphere, noise and visual pollution, and the destruction of wildlife habitats.

• The advantages and disadvantages of using fossil fuels, nuclear fuels and renewable energy sources to generate electricity. These include the cost of building power stations, the start-up time of power stations, the reliability of the energy source, the relative cost of energy generated and the location in which the energy is needed.

Answer 3

It is produced from the hot lava from the centre of the volcanoe which is underground

Answer 4

Well volcanoes are packed with thermal energy. So setting up a thermal power plant near a volcano can produce electricity. How it is generated is another question.
