They can be reproduced on a human timescale ⇒ Renewable resources

Renewable resources don't take millions of years to form like non-renewable resources. This allows for them to be renewed in a relatively short time.

They take millions of years to form ⇒ Non-renewable resources

Most non-renewable resources are fossil fuels and these take millions of years to form as they are the result of the remains of dead plants and animals being compressed over those millions of years.

They are produced naturally ⇒ Both Renewable and Non-renewable

Both types of resources are produced by natural processes. Fossil fuels are dead animals and plants and renewable resources like wind and solar are natural.

They are extracted by mining ⇒ Non-renewable resources

As mentioned, fossil fuels take millions of years to form and are formed by compression. This compression happens because the dead animals and plants are buried underground. To extract the fuels therefore, they need to be mined.

Their use as an energy source is increasing because they reduce pollution ⇒ Renewable resources

Renewable sources do not cause pollution like non-renewable sources so they are a preferred option when it comes to environmental damage.

the answer is c.) there is a warm front in region a and a stationary front in region b.
