The origin, existence and evolution of life on the earth depend on the negative entropy flow in the terrestrial system (TS). In this paper, we investigate the mechanisms of different negative entropy flows caused by the vertical heat transfer of water phase transition and the gravitational field effect, and the vertical atmospheric heat transfer and the gravitational field effect, under the influences of the suns radiation, the photosynthesis of the plants, and the earths rotation. The magnitude orders and the mechanisms of the abovementioned negative entropy flow are also discussed.
