Accepted Answer

Geothermal energy is used to produce steam, which is then used to turn turbines connected to generators, just like in conventional steam power plants.

Question 2

_____ is a form of energy not derived from sunlight.&#10;A) &#8203; Biomass fuel&#10;B) &#8203; Fossil fuel &#8203;&#10;C) &#8203; Wind energy &#8203;&#10;D) &#8203; Tidal energy

Accepted Answer

Tidal energy is derived from the gravitational pull of the moon and sun on Earth's oceans, not from sunlight.

Question 3

Underwater turbines are an alternate method of harnessing tidal energy that _____ . &#8203;&#10;A) &#8203; are effective but create noise pollution &#8203;&#10;B) &#8203; have superceded wind power in number and environmental impacts &#8203;&#10;C) &#8203; are not highly predictable &#8203;&#10;D) &#8203; can be much smaller than wind turbines of similar output &#8203;

Accepted Answer

Underwater turbines can be much smaller than wind turbines of similar output.

Question 4

&#8203;Geothermal reservoirs with temperatures _____ offer a source of direct heating for homes, offices, and greenhouses.&#10;A) &#8203;greater than 300&#176;F&#10;B) &#8203;less than 300&#176;F&#10;C) no greater than 220&#176;F&#10;D) &#8203;equal to or less than 220&#176;F

Accepted Answer

The answer of &#8203;Geothermal reservoirs with temperatures _____ offer a...

Question 5

&#8203;_____ power plants are the simplest and oldest design, making direct use of geothermal steam as it emerges from the ground.&#10;A) &#8203;Dry steam&#10;B) &#8203;Flash steam&#10;C) Binary cycle&#10;D) Hydroelectric

Accepted Answer

Dry steam power plants use geothermal steam directly as it emerges from the ground without any intermediate fluids. This design is the simplest and oldest type of geothermal power plant. Flash steam and binary cycle plants both use intermediate fluids, while hydroelectric power plants generate electricity using flowing water.

Question 6

Small quantities of long-lived radioactive isotopes within the earth, principally _____, give off roughly 30 trillion watts of heat.&#10;A) &#8203; potassium 40 and uranium 235 &#8203;&#10;B) &#8203; uranium 235 and uranium 238 &#8203;&#10;C) &#8203; u ranium 238 and thorium 232 &#8203;&#10;D) &#8203; thorium 232 and potassium 40 &#8203;

Accepted Answer

The long-lived radioactive isotopes within the earth that give off heat are primarily uranium 238 and thorium 232.

Question 7

The two forms of energy not derived from sunlight-tidal energy and geothermal energy-are small by comparison.

Accepted Answer

Tidal energy and geothermal energy are both forms of renewable energy, but their overall contribution to global energy production is small compared to other sources such as fossil fuels, hydropower, and wind power.

Question 8

Ultimately, the source of tidal energy is the kinetic energy of the _____ .&#10;A) &#8203; rotating earth &#8203;&#10;B) &#8203; moon phases &#8203;&#10;C) &#8203; sunlight &#8203;&#10;D) &#8203; plates beneath the ocean floor &#8203;

Accepted Answer

The source of tidal energy is the kinetic energy of the rotating Earth, which interacts with the gravitational forces of the moon (and to a lesser extent, the sun) to create tides.

Question 9

&#8203;Which of the following statements regarding non-solar energy is true?&#10;A) &#8203;Geothermal power plants provide intermittent electricity that is dependent on fluctuations in weather and planetary cycles.&#10;B) The lack of environmental concerns associated with tidal barrages make them more promising than underwater turbines.&#10;C) &#8203;The efficiency of converting geothermal heat into electricity is greater than that of conventional steam power plants.&#8203;&#10;D) &#8203;Tidal power is intermittent and does not always align with energy demands.

Accepted Answer

Tidal power is dependent on tides, which can be unpredictable and may not always align with energy demands.

Question 10

The environmental concerns associated with tidal barrages make them less promising than underwater turbines.

Accepted Answer

Tidal barrages can have negative impacts on local ecosystems and limit the movement of aquatic species, making them less environmentally friendly than underwater turbines.

Question 11

Accepted Answer

The answer of Ultimately, the source of tidal energy is...

Question 12

Like hydroelectric dams, tidal barrages cannot generate power by harnessing flow in both directions.

Accepted Answer
