As the fluid is heated it rises as the molecules get energy on heating, similarly the particles cool when they are condensers at a certain temperature that causes them to sink a similar pattern is found in the atmosphere also. The light arises and heavier air falls as it's dense and hence sinks again.
Similarly, the earth heating patterns that are derived from convection currents coming from the mantel are also derived from the tectonic processes from within the earth's interior.
Within the atmosphere and oceans are also found the wind and pressure belts that rotate in the spherical motion and derive up and down from the equator of the earth. The poleward cool air and hot air from the equator are mixed and create turbulence in the upper atmosphere in the form of Jet steams and westerlies and easterlies that derive the weather patterns around the globe.
The melting of the sea ice and rise in global temperature are having a profound impact on the distribution of land and water ration of the earth as much of the land is concentrated in the northern hemispheres and the rest of the areas are oceanic waters.
The presence of warm global temperature in the seas and continue expansion of the bottoms are thus spading this effect as a rise in 1 to 3 degrees caused a severe rise in the oceanic basins and this cause more salinity in the rivers and an increase in the global cooling staking over the oceans.
The population of freshwater and marine water is badly affected many species of corals have already died and a catastrophic bleaching has occurred on the western coast of Australia. Thus it poses a severe threat to the marine biology and ecology of the pant is due impacted by this.
More and more species are getting extinct and habits are getting lost and the planet is getting more heated and drastic release of temperature is causing more in tectonic movement in the polar areas.
