The following question based on Atmosphere & Climatology topic of indian geography mcq
(a) rotation of the earth
(b) revolution of the earth
(c) All the above
(d) uneven heating of the earth
The correct answers to the above question in:
Answer: (a)
If the Earth didn’t rotate, winds would travel either north or south due to differences in temperature and pressure at different latitudes. But since the Earth does rotate, the Coriolis force deflects these winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
The Coriolis Effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as largescale movement of air in the atmosphere or water in the ocean.
Such motions are constrained by the surface of the earth, so only the horizontal component of the Coriolis force is generally important. This force causes moving objects on the surface of the Earth to be deflected in a clockwise sense (with respect to the direction of travel) in the northern hemisphere, and in an anti-clockwise sense in the southern hemisphere.
