How were nonrenewable resources formed? a. by intense human labor b. by volcanic eruptions along the tectonic plates c. by geologic forces in the earth’s crust over millions of years d. by the power of running water

By intense human labor isn't how non-renewable resources are made.This is how man-made recources are formed.In this case the objects that were created are renewable because they can be re-made.

Volcanic erouptions does not create nonrenewable recources.They create cerain rock, also Valcanos erupt all the times and it doesn't take centeries for the lava too cool down and become a rock.

Geologic forces in the crust would be the best answer because, dead organisims pile up in sediments in the earths cruts for thousands, even millions of years.That means these can't be re-made in a short period of times.That being said this wuld be the best answer.

By the power of running is hydro-electricity which has nothing too do with nonrenewable recources.Also water is basicaly remade daily due to the water cycle.

 C. Geologic forces
