Geothermal Energy has absorbed inside the earth the thick layer of melted hot rock beneath the earth's crust, called magma, which is constantly being generated by radioactive elements such as uranium and potassium. Huge reserves of heat can meet our needs for thousands of years, below the 50f surface of the earth. Average temperature rise is found to be 10 ° C on going meter, it is attained up to 250 ° C when descending a few kilometers. Around the volcanic areas so that heat can be found at shallow depth. If we wish, we can effectively use the existing Geothermal energy sources in the earth & use. Let's test your knowledge about the Geothermal Energy test.
