GEOLOGY

Detailed explanation-1: -Volcanic deposits are enriched in elements such as magnesium and potassium. When volcanic rock and ash weathers, these elements are released, producing extremely fertile soils. Thin layers of ash can act as natural fertilisers, producing increased harvests in years following an eruption.

Detailed explanation-2: -Positive effects 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.

Detailed explanation-3: -There are many positive effects of volcanoes including: Fertile soils, tourism, geothermal energy, creation of new land and building materials. Volcanic soils are very fertile. These rich soils are called laterite soils and are rich in minerals.

Detailed explanation-4: -Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.
