To answer question 2, we need to identify the method used to harvest energy from water, wind, and geothermal vents.
Option A, aquaculture, is not the correct answer. Aquaculture refers to the cultivation of aquatic animals or plants, which is not directly related to energy harvesting.
Option B, engines, is also not the correct answer. Engines are devices that convert energy into mechanical work, but they are not specific to harvesting energy from water, wind, or geothermal vents.
Option C, mines, is not the correct answer. Mines are excavations in the earth's surface to extract minerals or other geological materials, and they do not directly involve energy harvesting.
Option D, turbines, is the correct answer. Turbines are devices that convert the energy from wind, water, or steam into mechanical energy, which can then be used to generate electricity. In the context of harvesting energy from water, wind, and geothermal vents, turbines are commonly used.
Therefore, the correct answer to question 2 is option D, turbines.
To answer question 3, we need to identify the advantage that does not apply to generating nuclear energy.
Option A states that nuclear energy does not release carbon dioxide into the atmosphere. This is true because nuclear energy does not produce greenhouse gases like fossil fuels do.
Option B suggests that generating nuclear energy does not require a specialized process or involve any risk. This statement is incorrect because nuclear energy requires complex and specialized processes to extract the energy from nuclear reactions. It also carries certain risks, such as the potential for accidents or the generation of radioactive waste.
Option C states that nuclear energy does not release chemicals that cause acid rain. This is true because nuclear energy does not produce sulfur dioxide or nitrogen oxide emissions, which are the primary causes of acid rain.
Option D suggests that generating nuclear energy does not contribute to air pollution. This statement is incorrect because although nuclear power plants do not emit greenhouse gases or conventional air pollutants during normal operations, there are concerns regarding the disposal of radioactive waste and the potential for accidents that could release harmful substances into the air.
Therefore, the correct answer to question 3 is option B, as it does not accurately represent an advantage of generating nuclear energy.
