Teacher..Im Laura


I havent blog for that reason a did the homeworks with saray`s blog:

1- Coal, oil, natural gas, or radioactive elements. They are considered non-renewable because once they are removed from the ground and used, they are not immediately replaced.

2- Renewable energy comes from the natural flow of sunlight, wind, or water around the Earth. Renewable energy on the other hand quickly replaces itself and is usually available in a never-ending supply.

I don't know how to do the questions number 3 and 4
