Impacts
Volcanoes have a large impact on their locality. They produce ash, lava, 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. Powerful eruptions are also associated with huge pyroclastic flows and volcanic bombs.
The effects of volcanoes can be both positive and negative.
Positive impacts
- Energy from the heat of the Earth. energy is where 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.
- Rising magma brings valuable minerals to the surface, creating mining opportunities.
Negative impacts
- 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.
- Habitats and landscapes are damaged by Molten rock that is released from the Earth's core in a volcano or fissure. flows.
Additionally, people choose to live near volcanoes because of positive impacts, but this can put people at great risk.
