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: -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.

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: -Atmospheric cooling. Land formation. Water production. Fertile land. Geothermal energy. Raw materials. 13-Jun-2018
