The earths contains 5 spheres. The Lithosphere, the biosphere, the cryosphere, the atmosphere, the hydrosphere, and the geosphere. The lithosphere is earths crust. The biosphere is everything that is living on earth. The cryosphere is solid ice on earth. The atmosphere is the gas on earth. The hydrosphere is all the water on earth.
