Amajor concern about increasing global temperatures is that a large portion of polar ice could detach and melt into the ocean. if this would happen, which two spheres would directly interact? a cryosphere and atmosphere b cryosphere and hydrosphere c cryosphere and biosphere d cryosphere and geosphere i think its either a or b ? ?

cryo represents ice-related things hydro represents water-related things Therefore answer is B on another note: atmo represents air-related things bio represents life-related things geo represents earth-related things

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
