It can be argued that Earth's magnetosphere makes complex multicellular, terrestrial life possible on this planet. The magnetic field that creates the magnetosphere is the result of processes that take place chiefly in:
The magnetic field in Earth that creates the magnetosphere which in turn makes life possible on Earth is found in the outer core of the earth. The outer core is the third layer of the earth and it is solely responsible for the magnetic field because as the Earth spins there is movement of the Iron located inside the liquid outer core.
