IV Answer in brief
What will happen if the Earth fails to states.
Dear Student,
If the earth stopped rotating completely, then we would get 1/2 year daylight and 1/2 year nighttime. Also During daytime for 6 months, the temperature would depend on the latitude, which result in more rise in temperature than it is now at the equator than at the poles where the light rays are more slanted and the heating efficiency is lower.
This long-term temperature would change the atmospheric wind circulation pattern so that the air would move from the equator to the poles rather than in wind systems parallel to the equator like they are now.
