Final answer:
Carbon in the soil can become fossil fuels such as oil and coal over millions of years. These fossil fuels are non-renewable resources and, when burned, contribute to the greenhouse effect and global climate change. The correct answer is c. it turns into fossil fuels like oil and coal.
Step-by-step explanation:
Carbon that has been in the soil for millions of years can turn into fossil fuels like oil and coal.
On land, carbon is stored in soil as a result of the decomposition of living organisms (by decomposers) or from weathering of terrestrial rock and minerals. This carbon can be leached into water reservoirs by surface runoff.
Deeper underground, carbon is stored in the form of fossil fuels -- the anaerobically decomposed remains of plants that take millions of years to form. These fossil fuels are considered a non-renewable resource because they regenerate very slowly or not at all, and their use far exceeds their rate of formation.
Deforestation reduces the number of trees that absorb carbon dioxide and store carbon in plant fibers. When fossil fuels are burned or wood is used, this carbon is released back into the atmosphere, contributing to the greenhouse effect and global climate change.
