Question: 1 / 400

What is a benefit of volcanic activity?

Destruction of habitats

Release of harmful gases

Creation of fertile soil

Geothermal energy

Volcanic activity provides several benefits, one of which is the generation of geothermal energy. This renewable energy source is produced from the heat stored beneath the Earth's surface, which is accessible in regions with volcanic activity. The heat can be harnessed to generate electricity or to provide direct heating for residential and industrial uses. Geothermal energy is a clean energy source with a low environmental impact, making it an attractive alternative to fossil fuels.

In addition to geothermal energy, volcanic eruptions can lead to the creation of fertile soil through the gradual breakdown of volcanic ash and rocks. This soil is rich in minerals, which can enhance agricultural productivity. Understanding both geothermal benefits and the fertility of volcanic soils illustrates the complex interplay between volcanic activity and ecological processes.
