If a large metcorite were to strike the earth in the near future, what effect might this event have on the atmosphere, in particular, average temperatures and climate?

Explanation:

Meteorite impacts on the earth surface are usually seen in the formation of craters on the surface. The impact of such massive body would produce heat radiation and send distrubances throughout the earth. Due to the impact, dust plumes would rise from the surface into greater reaches of the atmosphere and would also be carried throughout the planet by global wind circulation. The earth surface temperature would increase due to heat resulting from the frictional heating arising from the collision. The earth surface would warm and become hotter in the process.

The blasted dust would further exaggerate the heating. This dust would greatly prevent incoming solar radiation from reaching the earth surface and the heat from the bollide collision would be locked within the earth. This trapped heat and increasing temperature would greatly attenuate global climate. The trade winds would have considerably more dust particles and more cloud. In fact, the rainfall would be considerably hotter if it forms at all because of the increasing average surface temperatures. Polar ice would melt and oceans would rise. Earthquakes would be triggered because the earth has been disturbed.

Meteorite collision through geologic history has led to massive extinction of life on earth.

hi there!
