How about list 2 non-renewable sources. what makes them non-renewable?

Oil, and coal are two examples of non- renewable resources. They are both non- renewable because they take thousands of years to make and so we are consuming them faster than they can be replaced.

Coal and fossil fuels. Coal isn't renewable because once it's burnt up, it's gone and done with. Fossil fuels take literal millions of years to form, so it's pretty much nonrenewable once used. So, coal and fossil fuels are two examples.
