All Questions (13)
A) Combustion of natural gas
B) Solar radiation absorbed by the ground
C) Heat stored in the Earth’s interior
D) Friction from tectonic plate movement
Correct Answer: C
The provided text explicitly states that geothermal energy is obtained by 'using the heat stored in the Earth’s interior'.
A) To heat the Earth's interior
B) To drive an electric generator
C) To be sold as a secondary product
D) To condense back into water for heating
Correct Answer: B
According to the content, after water is heated, 'The steam is used to drive an electric generator.'
A) The release of hydrogen sulfide
B) The production of radioactive waste
C) Significant carbon dioxide emissions
D) Depletion of the ozone layer
Correct Answer: A
The text mentions a specific environmental drawback: 'it can cause the release of hydrogen sulfide.'
A) The high and fluctuating cost of water
B) The prohibitively expensive cost of accessing the energy
C) The low price of the electricity it produces
D) The expensive international tariffs on steam
Correct Answer: B
The content states, 'The cost of accessing geothermal energy can be prohibitively expensive'.
A) It is universally available and easy to access worldwide.
B) It is abundant but the technology to use it is rare.
C) It is not easily accessible in many parts of the world.
D) It is only accessible in polar regions.
Correct Answer: C
The text clearly indicates a limitation in availability, stating 'it is not easily accessible in many parts of the world.'
A) An electric generator creates steam -> steam heats water -> water is stored in the Earth.
B) Steam from the Earth's interior is captured -> it is used to heat surface water -> the hot water drives a generator.
C) Heat from the Earth's interior heats water -> the water becomes steam -> the steam drives a generator.
D) Hydrogen sulfide is burned -> the heat creates steam -> the steam drives a generator.
Correct Answer: C
The text outlines the process as: using 'heat stored in the Earth’s interior to heat up water, which is brought back to the surface as steam. The steam is used to drive an electric generator.'
A) High cost and the release of hydrogen sulfide
B) Inefficiency and the need for large land areas
C) Water pollution and noise pollution
D) High cost and excessive water usage
Correct Answer: A
The text lists two main drawbacks: 'The cost of accessing geothermal energy can be prohibitively expensive' and 'it can cause the release of hydrogen sulfide.'
A) Air
B) Oil
C) Water
D) Hydrogen sulfide
Correct Answer: C
The text specifies that the process involves using the Earth's heat 'to heat up water, which is brought back to the surface as steam.'
A) the necessary geological conditions are geographically restricted.
B) most countries lack the political will to develop it.
C) the cost of steam is too high in most markets.
D) international treaties prohibit its use in many areas.
Correct Answer: A
Since the energy source is the heat from the Earth's interior, its lack of accessibility implies that the conditions required to tap this heat (e.g., heat being close to the surface) are not found everywhere, but are limited to specific geographic locations.
A) Solar photovoltaic farm
B) Hydroelectric dam
C) Nuclear fission power plant
D) Wind turbine
Correct Answer: C
The text states 'The steam is used to drive an electric generator.' This is the same principle used in nuclear power plants, where heat from nuclear fission is used to create steam that drives a generator. Solar PV, hydroelectric, and wind power use different mechanisms (photons, water flow, and wind) to generate electricity.
A) The cost of labor and the proximity to cities
B) The cost of water and the local climate
C) The cost of accessing the heat source and its geographic availability
D) The cost of the generator and the risk of earthquakes
Correct Answer: C
The text explicitly points out two key challenges: 'The cost of accessing geothermal energy can be prohibitively expensive, and it is not easily accessible in many parts of the world.'
A) It converts the energy of moving steam into electricity.
B) It pumps water deep into the Earth's interior.
C) It generates the initial heat needed to create steam.
D) It captures and processes hydrogen sulfide gas.
Correct Answer: A
The text states that steam is 'used to drive an electric generator.' The function of a generator is to convert mechanical energy (the motion from the steam) into electrical energy.
A) A location with strong, consistent winds
B) A large, fast-flowing river
C) A geological formation where Earth's heat is accessible near the surface
D) A coastal location for access to seawater
Correct Answer: C
The entire process relies on 'using the heat stored in the Earth’s interior.' The fact that it is 'not easily accessible in many parts of the world' implies that a key requirement is a specific geological location where this heat can be reached, making this the most necessary component.
