Geothermal Energy Review

What is geothermal energy?

• Energy derived from the sun

• Energy derived from the Earth's internal heat

• Energy derived from wind

• Energy derived from water

Which ancient civilization is known to have used geothermal energy for bathing?

• Egyptians

• Romans

• Mayans

• Aztecs

Compare geothermal energy with solar energy in terms of reliability.

• Geothermal energy is less reliable than solar energy.

• Both are equally reliable.

• Geothermal energy is more reliable than solar energy.

• Solar energy is more reliable than geothermal energy.

Explain how the Earth's internal heat is generated.

• By the sun's rays penetrating the Earth's surface

• By the decay of radioactive materials and residual heat from the planet's formation

• By the movement of tectonic plates

• By the gravitational pull of the moon

Identify which of the following is a geothermal resource.

• Solar panels

• Hydrothermal systems

• Wind turbines

• Biomass

Compare the efficiency of geothermal energy with wind energy.

• Geothermal energy is generally more efficient than wind energy.

• Wind energy is generally more efficient than geothermal energy.

• Both have the same efficiency.

• Efficiency depends on the location and technology used.

Which method is used to harness geothermal energy directly for heating purposes?

• Photovoltaic cells

• Geothermal heat pumps

• Wind turbines

• Hydroelectric dams

Analyze the environmental benefits of using geothermal energy.

• It produces high levels of greenhouse gases.

• It has a low carbon footprint and minimal land use.

• It requires large areas of land.

• It depletes water resources.

Evaluate the main challenge of geothermal energy development.

• High initial costs and site-specific resource availability

• Lack of technology

• High operational costs

• Inconsistent energy output

What is the primary component of Earth's heat that is harnessed in geothermal energy?

• Solar radiation

• Radioactive decay

• Wind currents

• Ocean tides
