Why is geothermal activity significant in volcanic island arcs?

• A. It decreases the eruption frequency
• B. It enhances biodiversity in the area
• C. It is a source of renewable energy
• D. It contributes to soil erosion

Answer: (C)

Geothermal activity is significant in volcanic island arcs primarily because it serves as a source of renewable energy. Volcanic island arcs are formed as tectonic plates converge, leading to the melting of the subducted plate and the formation of magma. This geothermal energy originates from the heat produced within the Earth's mantle, which can be harnessed for various uses, including electricity generation and direct heating systems. The presence of geothermal energy in these regions not only underscores the geological processes at play but also highlights the potential for sustainable energy solutions. As communities and countries seek to reduce reliance on fossil fuels and combat climate change, the utilization of geothermal energy becomes increasingly valuable. While the other choices might have some relevance in specific contexts, they do not capture the primary role of geothermal activity in volcanic island arcs as effectively as the potential for renewable energy production does.
