The correct answer is option A, that is, the Earth is spinning on its axis.  

The westerlies refer to the prevailing winds that blow from the west to the east in the mid-latitudes, that is, in between 10 and 60 degrees. The wind blows from the regions of higher pressure to the region of lower pressure, but it does not blow in a straight line.  

This is generally because the Earth is rotating on its axis. The spin of the Earth makes winds to bend towards the right in the northern hemisphere and towards the left in the southern hemisphere. This is known as the Coriolis effect.

Can someone give me an example of negative and positive feedback?
Archy [21]
A negative feedback example is Human body temperature - The hypothalamus of a human responds to temperature fluctuations and responds accordingly. If the temperature drops, the body shivers to bring up the temperature and if it is too warm, the body will sweat to cool down due to evaporation.
