Science 6B - 3.7d

What is the main idea of a text discussing hydroelectric generators, a stream, and the use of potential and kinetic energy?

• The environmental impact of hydroelectric generators.

• How hydroelectric generators convert the energy of a stream into electricity.

• The history of hydroelectric power.

• Different types of renewable energy sources.

Which detail would you most likely find in a text about hydroelectric generators using a stream?

• The number of solar panels installed globally.

• The process of photosynthesis in plants.

• How the potential energy of water is converted into kinetic energy.

• The migration patterns of birds.

What can be inferred about the location of hydroelectric generators?

• They must be located in urban areas.

• They are only effective in coastal regions.

• They need to be situated where there is a consistent flow of water.

• They are most effective in desert climates.

The word "harnessing" in the context of hydroelectric power most likely means:

• Wearing safety equipment.

• Controlling and making use of.

• Tying up.

• Repairing.

Which text structure is primarily used in a discussion about how hydroelectric generators work?

• Cause and effect.

• Compare and contrast.

• Sequence/Process.

• Problem and solution.

How could you best summarize a text about hydroelectric generators?

• Hydroelectric generators are a type of renewable energy source that uses the flow of water to generate electricity.

• Hydroelectric generators are harmful to the environment.

• The history of hydroelectric power dates back hundreds of years.

• Many countries are shifting from fossil fuels to hydroelectric power.

What argument might be made in favor of using hydroelectric generators?

• They produce significant amounts of greenhouse gases.

• They can operate at any time of the day or night, regardless of weather conditions.

• They require large amounts of fossil fuels to operate.

• They are very expensive to build and maintain.

Which claim about hydroelectric power needs evidence to be considered valid?

• Hydroelectric power uses the flow of water to generate electricity.

• Hydroelectric power is the leading cause of river pollution.

• Hydroelectric generators convert kinetic energy into electrical energy.

• Hydroelectric power stations can be built on any size of river.

What inference can be made about the efficiency of hydroelectric generators compared to fossil fuels?

• Hydroelectric generators are less efficient because water is a less reliable source.

• Hydroelectric generators are more efficient because they use renewable resources.

• There is no difference in efficiency between the two energy sources.

• Fossil fuels are more sustainable than hydroelectric power.

Analyzing the text structure, what would come after a section explaining the concept of potential energy in the context of hydroelectric power?

• A discussion on the environmental impacts of hydroelectric power.

• An explanation of how potential energy is converted into kinetic energy.

• A comparison between hydroelectric power and solar power.

• A conclusion summarizing the benefits of hydroelectric power.
