Atmosephere, Hydroshere, Lithoshere,Geosphere

Lithosphere:is the rigid outermost shell of a rocky planet. On Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.(copied from the begining of wikipedia)

Geosphere:The term geosphere is often used to refer to the densest parts of Earth, which consist mostly of rock and regolith.[1] The geosphere consists of the inside of the Earth or other planets or bodies.(copied from the begining of wikipedia)

Atmosphere:An atmosphere is a layer of gases that may surround a material body of sufficient mass,[3] and that is held in place by the gravity of the body. An atmosphere may be retained for a longer duration, if the gravity is high and the atmosphere's temperature is low. Some planets consist mainly of various gases, but only their outer layer is their atmosphere. (copied from the begining of wikipedia)

Hydrosphere:A hydrosphere (from Greek ὕδωρ - hydor, "water" and σφαῖρα - sphaira, "sphere") in physical geography describes the combined mass of water found on, under, and over the surface of a planet. (copied from the begining of wikipedia)
