On a global basis, which of the following is the largest reservoir of carbon
a. atmosphere
b. vegetation
c. sediments
d. fossil fuels

Answer;

Fossil fuels

On a global basis, fossil fuels form the largest reservoir of carbon.

Explanation;;

Carbon dioxide gas is found in the atmosphere, carbonate rocks that are found in many locations on Earth and carbon-based fossil fuels that are found deep on the Earth.

-The major reservoirs of carbon include, the atmosphere, terrestrial biosphere, the ocean, the sediments (such as fossils fuels, fresh water systems) and the Earth's interior.

-The carbon exchanges between reservoirs occur as the result of various chemical, physical, geological, and biological processes.

-The ocean contains the largest active pool of carbon near the surface of the Earth.

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom
