Which of the following best describes the use of a renewable resource? (2 points)
ANSWER:
C. There are areas in California that use the heat from deep in the Earth to generate electricity.
The answer is Option C as it is the only option which refers to a renewable energy resource. The renewable source which it refers to is geothermal energy as it is heat obtained from deep within the Earth which is utilised to produce electricity. Therefore, Option C is the answer.

Which of the following best describes the use of a non-renewable resource? (2 points)
ANSWER:
C. Natural gas is a great alternative to electricity for cooking.
The answer is Option C as it is the only option which refers to a non-renewable energy resource. Natural gas is a non-renewable resource as it was formed from the buried remains of plants and animals who were alive a significantly long time ago, thus making them fossil fuels. As all fossil fuels are non-renewable, natural gas must be a non-renewable resource. Therefore, Option C is the answer.

Which of the following best describes the use of a renewable resource? (2 points)
ANSWER:
D. Solar panels are able to gather the energy from the sun and convert it into electrical energy.
The answer is Option D as it is the only option which refers to a renewable energy resource. The renewable resource it refers to is solar energy as solar panels are utilised in order to produce solar energy for electricity. Solar energy is renewable as it utilises the sun's energy in the form of heat and light energy. As the sun's energy is unlimited and renewable resources are meant to be unlimited, solar energy must be a renewable energy resource. Therefore, the answer must be Option D.
QUESTION 4 -
Select the example that best describes a renewable resource. (2 points)
ANSWER:
B. My town is powered by electricity that is generated by the energy from the flow of water through a large dam.
The answer is Option B as it is the only option which refers to a renewable energy resource. The renewable resource it refers to is hydroelectricity also known as hydropower as it utilises energy from the flow of water in a large controlled dam. Hydropower is renewable as it utilises energy from the flow if water which is an unlimited resource. As hydropower is unlimited and renewable energy is meant to be unlimited, hydropower must be a renewable resource. Therefore, the answer must be Option B.
QUESTION 5 -
Which example describes a non-renewable resource? (2 points)
ANSWER:
D. There are drilling platforms all along the coast that are used to drill for natural gas that can be used to generate electricity.
The answer is Option D as it is the only option which refers to a non-renewable energy resource. Natural gas is a non-renewable resource as it was formed from the buried remains of plants and animals who were alive a significantly long time ago, thus making them fossil fuels. As all fossil fuels are non-renewable, natural gas must be a non-renewable resource. Therefore, Option D is the answer.
When adding a solute to the solvent, the solution will then boil at a point much higher than the solvent itself. Therefore, it would take much longer for the solution to boil. Among the choices, the correct answer would be B. The water will boil at a higher temperature.
Amplitude is a measurement of the magnitude of displacement (or maximum disturbance) of a medium from its resting state, as diagramed in the peak deviation example below (it can also be a measurement of an electrical signal's increased or decreased strength above or below a nominal state).
