How is geothermal energy formed?

• Caused by friction between the layers of the earth

• From chemical reactions between rocks inside the earth

• Due to air pressure in the earth's core

• Residual heat from the formation of this planet and radioactivity in the earth's core

What are the uses of geothermal energy?

• Waste processing, paper making, and plastic production

• Making musical instruments, household furniture, and electronic devices

• Power generation, heating, and air conditioning.

• Making jewelry, making toys, and textile production

Explain geothermal power generation technology.

• Geothermal power plants use wind energy to generate electricity.

• Geothermal power plants use solar energy to generate electricity.

• Geothermal power plants use waterfall energy to generate electricity.

• Geothermal power plants use heat from within the earth to generate electricity.

What is the environmental impact of geothermal energy use?

• Reduces greenhouse gas emissions and decreases dependence on fossil fuels.

• Degrades air and water quality around geothermal energy sites.

• Has no impact on the environment.

• Increases greenhouse gas emissions and increases dependence on fossil fuels.

What causes geothermal energy?

• Solar heat absorbed by the earth
