what is geo thermal energy and how we can use it.???
Answers
Answer:
Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet and from radioactive decay of materials.
These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly. Geothermal energy has been used for thousands of years in some countries for cooking and heating.

Answer:
These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly.
Explanation:
GEOTHERMAL ENERGY HAS been used for thousands of years in some countries for cooking and heating. It is simply power derived from the Earth’s internal heat.
This thermal energy is contained in the rock and fluids beneath Earth’s crust. It can be found from shallow ground to several miles below the surface, and even farther down to the extremely hot molten rock called magma.
How Is It Used?
These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly.
A geothermal heat pump system can take advantage of the constant temperature of the upper ten feet (three meters) of the Earth’s surface to heat a home in the winter, while extracting heat from the building and transferring it back to the relatively cooler ground in the summer.
Geothermal water from deeper in the Earth can be used directly for heating homes and offices, or for growing plants in greenhouses. Some U.S. cities pipe geothermal hot water under roads and sidewalks to melt snow.
