List the sentences. keep in mind when you use sarcasm you are saying one thing in a tone to make it clear you are joking. like for instance, pretend you get a math test from your teacher. you’d most likely say, “oh yay.. a math test.” but you’d have the tone to give it the “oh come on” feeling. does this at all?

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.
