Carbon dating animation
The ocean naturally contains many dissolved chemicals which are especially important to the ocean carbon cycle and the shell-building organisms that live in the oceans.
If you examined a sample of sediments from these cliffs, you would find shells of microscopic coccolithophores and foraminifera that lived, died and then sank to the sea floor millions of years ago. Choose two of the following and describe their role in the ocean's biological pump.Carbon continually moves through these parts of the Earth system. The carbon cycle is one of the biogeochemical cycles.Other biogeochemical cycles include the water cycle and the nitrogen cycle.In biogeochemical cycles, elements are transported between the atmosphere, biosphere (living things), hydrosphere (water) and geosphere (rocks, minerals, and soils).Thus, these cycles are excellent examples for teaching about Earth as a system.
