• Ash and dust will prevent sunlight from penetrating the Earth's surface.

Question 17

• Which statement below is TRUE about geothermal power plants and geothermal heat plants
• Geothermal power plants use the heat from deep inside the Earth and used to produce steam to generate electricity while geothermal heat pumps use the heat coming from close to the Earth's surface to heat water or provide heat for buildings.

Question 18

• Which sequence below is correct on how the heat from the Earth is tapped as a source of electricity in a power plant?
