The positive and negative effects of volcano eruptions
Volcanoes have a large effect on their locality. They produce ash, Molten rock that is released from the Earth's core in a volcano or fissure. , Large blocks of hot rock thrown from a volcano., A current of hot gas and rock that flows downhill at high speed. and A destructive volcanic landslide or mudflow, consisting of a mixture of volcanic debris, mud, rock and water.. Ash from large volcanoes has been known to affect global climates.
The effects of volcanoes can be both positive and negative.
Positive effects
- Energy from the heat of the Earth. energy is when heat from within the Earth is used to generate electricity. Geothermal energy can be generated in areas where Molten rock that is found within the Earth. lies close to the surface. This is good for increasing renewable energy use.
- Ash ejected by the volcano acts as a good fertiliser for soils.
- Volcanoes attract many tourists, who enjoy the dramatic scenery that they produce.
Negative effects
- Volcanoes are dangerous. They can kill people and damage property.
- Economic activity can suffer as it is hard for businesses to operate after an eruption.
