What can you infer about the distribution of the effects of climate change? “the world’s least developed countries contribute only 10 percent of annual global carbon dioxide emissions.” a) the poorest countries contribute very little to climate change and feel less of its effects. b) the poorest countries are the main source of annual global carbon dioxide emissions. c) the poorest countries are responsible for climate change. d) the poorest countries contribute the least, but are impacted the most by climate change. 20pts lol

D) The poorest countries contribute the least, but are impacted the most by climate change. I would say that this is the correct answer as evidenced by the suffering and devastation wreaked on the Caribbean islands by the hurricanes last fall which are mostly tiny countries without heavy industry and with few automobiles.

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.
