Answers
☺ Good morning ☺
When a volcano erupts it throws out a lot of ash. At short notice this ash can be very harmful to the environment, but on the long term the ash layer, which contains many useful minerals, will be converted to a very fertile soil. Nearly everywhere volcanoes are located people use the rich soil for farming.
Answer:
CAUSES
the buoyancy of the magma, the pressure from the exsolved gases in the magma are the two causes of volcanic eruption.
ADVANTAGES OF VOLCANIC ERUPTION:
Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations.
The internal heat associated with young volcanic systems has been harnessed to produce geothermal energy
