  1. can be exhausted within dozens or hundreds of years.

  2. exist in a fixed quantity.

  3. are renewable, but only over millions or billions of years.

  4. all of the choices.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Nonrenewable resources exist in finite quantities, take millions of years to form, and are depleted much faster than they can be replaced. Therefore, all the provided descriptions are accurate.

Multiple choice

Renewable resources are...

  1. Resources that can be used one time then never again

  2. Resources that are no longer in use and are extinct

  3. Resources that can't be renewed

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Renewable resources are those that can be replenished naturally over a short period. Since options A, B, and C describe non-renewable or incorrect concepts, 'None of the above' is the correct choice.

Multiple choice

Renewable resources are resources that....

  1. cannot make anymore

  2. take millions of years to make more

  3. can make more
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Renewable resources are defined by their ability to be replenished or regenerated naturally within a human timescale, unlike nonrenewable resources.

Multiple choice

Nonrenewable resources

  1. can be exhausted within dozens or hundreds of years.

  2. exist in a fixed quantity.

  3. are renewable, but only over millions or billions of years.

  4. all of the choices.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Nonrenewable resources exist in finite quantities, take geological time to form, and are consumed faster than they are replaced. All listed options correctly describe these properties.

Multiple choice

What is one of the drawback of hydroelectric power?

  1. cost

  2. wastes water

  3. environmental impact

  4. unreliable
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hydroelectric dams can significantly alter ecosystems, disrupt fish migration, and flood large areas of land. While cost is a factor, environmental impact is a primary, widely recognized drawback.

Multiple choice

Which of the following is NOT an alternative energy?

  1. tidal

  2. geothermal

  3. natural gas

  4. hydrogen
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Natural gas is a fossil fuel, which is a non-renewable energy source. Tidal, geothermal, and hydrogen are all considered alternative or renewable energy sources.

Multiple choice

Why are trees and vegetation considered a renewable resource?

  1. they are not man made

  2. they can regrown within our life span

  3. they can not be regrown in our lifetime

  4. they require minerals to grow
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Renewable resources are those that can be replenished naturally within a human timeframe. Trees and vegetation grow back relatively quickly compared to fossil fuels.

Multiple choice

What is an example of a renewable resource?

  1. gold

  2. copper

  3. coal

  4. water
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water is part of the hydrologic cycle and is constantly replenished by precipitation, making it a renewable resource. Gold, copper, and coal are finite and non-renewable.

Multiple choice

What is a non-renewable resource?

  1. nat resource that can't be remade/regrown in our lifetime

  2. nat resource that can be remade/regrown in our lifetime

  3. nat resource that is no longer in existence

  4. natural resource that is man made
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Non-renewable resources exist in finite amounts and take millions of years to form, meaning they cannot be replaced within a human lifespan. Fossil fuels like coal and oil are classic examples.

Multiple choice

What is one of the drawbacks of hydroelectric power?

  1. increased human recreation

  2. noise pollution

  3. environmental impact

  4. possible electrocution
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hydroelectric dams disrupt river ecosystems, block fish migration, and change water temperatures, which are significant environmental impacts.

Multiple choice

Hydroelectric power uses the energy from?

  1. wind

  2. rivers

  3. hurricanes

  4. lightning
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hydroelectric power plants capture the kinetic energy of flowing water in rivers to spin turbines and generate electricity.

Multiple choice

Fossil fuels are ______ resources.

  1. nonrenewable

  2. non polluting

  3. renewable

  4. cool
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fossil fuels take millions of years to form, meaning they cannot be replaced on a human timescale. Therefore, they are considered nonrenewable resources.
