whats the answer?
and why?
The correct answer is rocks and sediments.
Rocks and sediments are considered the largest carbon reservoir due to the immense amount of carbon stored in the Earth's crust. This carbon is primarily stored in carbonate rocks, such as limestone, and organic-rich sediments, such as shale. These reservoirs have accumulated carbon over millions of years through geological processes like weathering, erosion, and sedimentation.
While fossil fuels, such as coal, oil, and natural gas, also contain a significant amount of carbon, they are considered a subset of the larger rocks and sediments reservoir. Fossil fuels are formed from the remains of ancient organisms that were buried and transformed over millions of years, making the carbon within them part of the larger carbon cycle and reservoir of rocks and sediments.
The terrestrial biosphere, which includes forests, grasslands, and other vegetation, also store a substantial amount of carbon. However, it is not considered the largest carbon reservoir when compared to rocks and sediments.
