Question

question #11
oil, natural gas, and coal resources are being depleted by humans.
which statement represents a disadvantage of using energy from fossil fuels?
a the formation of new fossil fuels will take a long time compared to how quickly it is now being consumed.
b the formation of new fossil fuels will take a short time compared to how slowly it is now being consumed.
c there is a surplus of renewable resources to use in place of fossil fuels.
d there is a shortage of renewable resources to use in place of fossil fuels.
question #12
how can fossil fuels best be described?
a natural source of energy that comes from the remains of living things
b synthetic source of energy that is made from the remains of living things
c mineral that is mined from the earth and used as a source of energy
d solid substance that can be mined from the earth and used as a source of energy

Explanation:

Question #11

To determine the disadvantage of fossil fuels, we analyze each option:

• Option A: Fossil fuels form over millions of years (long time), and we consume them quickly. This is a disadvantage as resources deplete faster than they're replenished.
• Option B: Incorrect, as fossil fuel formation is not short - it's very slow compared to consumption.
• Option C: There isn't a surplus of renewable resources to fully replace fossil fuels yet.
• Option D: While renewable resources are being developed, the statement about a "shortage" to replace fossil fuels isn't the main disadvantage related to fossil fuel use itself (the main issue is fossil fuel depletion rate).

To describe fossil fuels:

• Option A: Fossil fuels (oil, gas, coal) are natural, formed from the remains of ancient living organisms (plants, animals) over millions of years. This is correct.
• Option B: Fossil fuels are natural, not synthetic (synthetic would be human - made).
• Option C: Fossil fuels are not minerals. Minerals have a definite chemical composition and crystalline structure, while fossil fuels are organic.
• Option D: Not all fossil fuels are solid (e.g., natural gas is gaseous, oil can be liquid), so this is incorrect.

Answer:

A. The formation of new fossil fuels will take a long time compared to how quickly it is now being consumed.
