Abby is wrong
plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz help
i rreally need help i have a test
i was right it is d oh and thanks for all the help
I got 2 out of 15

abby is very very wrong
The correct answer is "the turning of circulating air currents." To understand why this is the case, we need to delve into some basic principles of air movement.
Air moves due to differences in air pressure. When air pressure is higher in one area compared to its surroundings, air will naturally flow from the higher pressure area to the lower pressure area. This movement of air creates wind.
One major factor that causes these pressure differences and consequently drives wind circulation is the rotation of the Earth. As the Earth rotates on its axis, the air near the equator moves faster at its surface than the air near the poles. This difference in speed creates a phenomenon known as the Coriolis effect. The Coriolis effect causes moving air to veer to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, which leads to the formation of large-scale wind patterns, such as the trade winds and prevailing westerlies.
These wind patterns contribute to the turning of circulating air currents. Air moves in a cyclic manner, where warm air at the equator rises, moves towards the poles at higher altitudes, cools, and eventually descends near the poles. The descending air then moves back towards the equator along the surface, completing the cycle.
However, while temperature differences between the hemispheres and the constant density of air do play a role in the overall atmospheric dynamics, they are not directly responsible for the turning of the circulating air currents, which is specifically caused by the Coriolis effect.
