Matter and energy ows between all the spheres. Atmosphere - envelope of gases around our planet. Biosphere - living and dead organic matter (not the same as ecosphere) Hydrosphere (and cryosphere which is the frozen part of the hydrosphere) In the ecosphere, the only part we consider is the upper part/crust of the earth. Look at map of biosphere map in oceans in slides. In the oceans, note that much of the chlorophyll is found around the poles and close to land, the middle of the oceans aren"t very active in plant growth. The interaction of the lithosphere, hydrosphere, and atmosphere on which the biosphere resides; the area of interaction. >it is important to wrap your head around the impact of time on earth"s history. Humans have only been here for a very small amount of time. There is a a con ict between the technosphere and the other natural spheres of the earth.
