You've already chosen the best response. There are many spheres, like biosphere, geosphere, lithosphere, atmosphere, hydrosphere, cryosphere. The geosphere is the earth itself, the rock,sand,lava etc. It consits of the crust, upper mantle, lower mantle, outer core and inner core.
The hydrosphere is found on the surface of Earth, but also extends down several miles below, as well as several miles up into the atmosphere. Most of Earth's water is salty and in the oceans-about 97%. Two-thirds of the remaining 3% is frozen in glaciers and polar ice caps.he Geosphere. Since 'geo' means 'ground,' the geosphere describes all of the rocks, minerals and ground that are found on and in Earth. This includes all of the mountains on the surface, as well as all of the liquid rock in the mantle below us and the minerals and metals of the outer and inner cores.
