Which statement best describes the long-term effects of using non-renewable resources?

a. burning fossil fuels pollutes the environment.
b. fossil fuels burn clean, reducing air pollution.
c. as populations increase, the need for solar power will decrease.
d. resources will replenish over the long term to be used again.

A

Explanation:

I have done this by the process of elimination.

B is not correct because Fossil Fuels do not burn clean, and definitely do not reduce air pollution

C is not correct, because it is likely that as populations increase, we will rely on more power, and since assumably it takes time for populations to increase, the earth will be in need for more renewable ways to power the devices we enjoy today.

D The definition of non-renewable energy is that it cannot be recovered, when coal is burned, the energy it generates is used for powering something, but the coal is no longer in existence, therefore this is not correct.

A makes the most sense.

The answer is A. Burning fossil fuels pollutes the environment.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
