2 ?s which does not cause major changes to aquatic ecosystems and where are minerals and fossil fuels found?

Temperature would change it because it would mess with the water currents, and the light penetration would probably do the same, yet not as much. the precipitation would be my guess, but then again I'm not a scientist. As for the minerals and fossil fuels, the Troposphere would be the air, the Lithosphere would be the earth, and the Biosphere would be the sum of all ecosystems, so the answer is the lithosphere
