Answer:
1. Plate boundaries and volcanoes, or in mountainous terrain.
2. The presence of hot magmas below the surface of active volcanic regions offers the prospect of harnessing a huge amount of geothermal energy (that's why they're related).
3. Geothermal energy uses the heat trapped beneath the Earth's surface to generate electricity.
4. Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, to heat buildings, and to generate electricity.
5. The Philippines is one of the world's top producers of geothermal power, owing to its location along the Ring of Fire zone of Pacific volcanoes. The country commissioned the 12-megawatt Maibarara Geothermal Power Plant-2 on March 9 2018.
