Answer:
The correct answer is A. Fossil fuels are cheaper than alternative forms of energy
Explanation:
Fossil fuels are made from organic matter of dead animals and mainly plants who were buried in the soil over hundred and thousand of years. We use fossil fuels because they are the best source to provide energy in the current time.
Fossil fuels are easily available and are present in very large amount which is the main reason for it to be cheaper. Fossil fuels like coal, petroleum or natural gas are more cheaper and efficient than alternative forms of energy like solar or wind energy.
But in future these fossil fuel will not be there and alternative forms of energy will become the primary and cheaper source of fuel.
Answer: Option A
Explanation:
Fossil fuels are formed inside the earth when dead plant and animal remains have enormous pressure on them. They get converted into coal and other types of fossils fuels.
They are not that that costly and is used by people at different places as it is so economical.
These are cheaper than other other sources of fuels. These are available in huge amount inside the earth and can be used for a very longer period of time with a very cost.

Well, if it gets TOO cold or TOO hot, it dies (like humans). But when it gets a bit colder then it's normal habitat, the metabolism will slow down, making it look sleepy, and sluggish. If it gets too hot, the metabolism will speed up, making it seem hyper and energetic.
