    In a hydroelectric dam, what drives the turbine to create electricity?

    • Falling water from the reservoir to the river

    • Evaporation

    • Flooding

    • Movement of water upstream

    Correct Answer
    A. Falling water from the reservoir to the river
    Explanation
    In a hydroelectric dam, the turbine is driven by the falling water from the reservoir to the river. As the water falls, it gains kinetic energy, which is used to turn the turbine blades. This rotational motion is then converted into electricity by the generator connected to the turbine. Evaporation, flooding, and movement of water upstream do not directly drive the turbine to create electricity in a hydroelectric dam.

    The process of turning corn into ethanol is called

    • Electrolysis

    • Ethanation

    • Fermentation

    • Seperation

    Correct Answer
    A. Fermentation
    Explanation
    Fermentation is the correct answer because it is the process of converting sugars present in corn into ethanol by the action of yeast or bacteria. During fermentation, the enzymes in the yeast break down the sugars into ethanol and carbon dioxide. This process is widely used in the production of ethanol as a biofuel. Electrolysis is not the correct answer as it is a process of using an electric current to drive a chemical reaction, and it is not typically used in the production of ethanol from corn. Ethanation and separation are not relevant to the process of turning corn into ethanol.

    Tidal power can meet the energy demands of only coastal cities

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Tidal power is a form of renewable energy that harnesses the natural rise and fall of ocean tides to generate electricity. This power source is primarily located near coastal areas where there is a significant tidal range. Therefore, it is true that tidal power can only meet the energy demands of coastal cities as they have access to the necessary tidal resources. Inland cities, far from the coast, do not have access to tidal power and would need to rely on other sources of energy to meet their demands.

    • Drilling into rock formations underground

    • Electrolysis of water

    • Extraction from the atmosphere

    • All of the above

    Correct Answer
    A. Electrolysis of water
    Explanation
    Electrolysis of water is the process of splitting water molecules into hydrogen and oxygen using an electric current. This is a common method used to obtain hydrogen fuel for fuel cells. By passing an electric current through water, the water molecules break apart, and the hydrogen gas can be collected and used as fuel. This process is considered a sustainable and environmentally friendly way to produce hydrogen fuel, as it only requires water and electricity as inputs. Therefore, electrolysis of water is a viable method to obtain hydrogen fuel for powering a fuel cell.

    What drives the turbine to produce electricity in a geothermal power plant

    • Hot magma that pours through the turbine

    • Hot rocks that radiate heat

    • Steam produced by magma close the surface

    • Steam produced by sunlgiht

    Correct Answer
    A. Steam produced by magma close the surface
    Explanation
    The correct answer is steam produced by magma close to the surface. In a geothermal power plant, steam is produced when water comes into contact with hot rocks or magma deep underground. This steam is then channeled through a turbine, which spins as a result of the high-pressure steam flow. The spinning turbine drives a generator, producing electricity. Therefore, it is the steam produced by magma close to the surface that drives the turbine and ultimately generates electricity in a geothermal power plant.

    Which of the following is true about building dams for electricity

    • Dams are cheap to build and do not produce any pollution during construction

    • Dams are an ecologically friendly method of electricity production and do not harm biodiversity

    • Dams flood the ecosystem upstream destroying it

    • Dams help insure healthy salmon populaions

    Correct Answer
    A. Dams flood the ecosystem upstream destroying it
    Explanation
    Dams flood the ecosystem upstream and destroy it because the construction of dams involves creating a reservoir by blocking a river or stream, which leads to the flooding of the surrounding land. This flooding disrupts the natural ecosystem and can result in the loss of habitat for various plant and animal species. Additionally, the altered water flow and temperature caused by the dam can further harm biodiversity and negatively impact the overall health of the ecosystem.

    Which of the following is a benefit to using ethanol made from corn?

    • Less soil erosion and land use

    • Cheaper to produce than gasoline

    • Renewable

    • Less dependence on foreign oil

    Correct Answer(s)
    A. Renewable
    A. Less dependence on foreign oil
    Explanation
    Ethanol made from corn is considered a renewable source of energy because corn can be grown and harvested repeatedly. This means that as long as there is a steady supply of corn, ethanol production can continue indefinitely. Additionally, using ethanol made from corn reduces the dependence on foreign oil because it can be produced domestically. This reduces the need to import oil from other countries, therefore increasing energy security and decreasing reliance on foreign sources.

    Check the box next to each renewable energy resource that uses sunlight either directly or indirectly

    • Ethanol produced from corn

    • Hydroelectric power

    • Wind turbines

    • Geothermal power

    Correct Answer(s)
    A. Ethanol produced from corn
    A. Hydroelectric power
    A. Wind turbines
    Explanation
    Ethanol produced from corn is a renewable energy resource that indirectly uses sunlight. Corn, as a plant, undergoes photosynthesis to convert sunlight into energy, which is then used to produce ethanol. Hydroelectric power is another renewable energy resource that indirectly uses sunlight. Sunlight evaporates water, which then condenses and falls as rain, filling rivers and reservoirs. The flowing water is used to generate electricity. Wind turbines directly use sunlight as wind is created by the uneven heating of the Earth's surface by the sun. Geothermal power, on the other hand, does not directly or indirectly use sunlight, as it harnesses the Earth's internal heat.
