(check all that apply.] they form on the deep sea floor where methane molecules are trapped in ice crystals. they represent a type of lithogenous sediment. in total, gas hydrate deposits are estimated to hold more carbon than all other forms of fossil fuel (coal, oil, natural gas) combined. the release of methane from the ocean floor to the atmosphere could have dramatic effects on global climate

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.
