1 - carbon dioxide is mainly found in the lithosphere, and in the ocean ( generally in larger bodies of water)
2 - global warming + pollution + population increase + cutting down forests has all factored toward the growing amount of carbon dioxide in our atmosphere.
3 - carbon cycle on land moves faster than in water
on land the caarbon is czarried whereas in the water carbon is dissolved
plants and animals help both in water and land carry out the carbon cycle
both land and water have many carbon resources such are sediments and rocks.
