The more carbon dioxide, the more the atmosphere warms up due to the greenhouse effect.
Greenhouse effect- greenhouse gases trap the suns heat making the earth warmer
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subduction back into the earth.
The appropriate answer is a. The Tetons. Continental to continental plate collision occurs when continental crust comes together and compression and folding and faulting over time leads to the formation of extensive fold mountain ranges. The Appalachians, The Alps and the Himalayas were all formed at continental collision plate margins. <span />
I believe it is East and West Germany because it has to do with the Berlin Wall which seperated Germany.
