The correct answer is - plate tectonics.
The convection currents in the mantle, are having very high temperatures and very high pressures. Because of that, they managed to crack the crust, and thus divide the surface of the Earth in multiple peaces, or as we call them, tectonic plates. The very high pressure from bellow manages to push the tectonic plates in certain direction, and even though that movement is only a couple of cm per year, on the long term it has huge effects on everything on the planet.

Explanation:
<em>The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat.</em> Gases in the atmosphere such as CO2, water vapor, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons absorb and re-radiate the sun's energy maintaining the Earth's temperature at around 33 degrees Celcius, this happens especially with infrared light that wants to go back to space. This infrared heat spreads back to the land and oceans. This absorption does not happen with visible light, the radiation at 400-800nm easily passes through the atmosphere.
