Air masses in Hadley cells descending to Earth at approximately 30˚ north and south latitude create what conditions on land? A. high levels of rainfall B. cold conditions C. dry conditions D. strong wind patterns flowing east to west

Air masses in Hadley cells descending to Earth at approximately 30°N and south latitudes create strong wing pattern flowing east to west.

Explanation:

The wind flow is called as trade winds.The loop of Hadley cell begins at the equator region where the climate is hot.

The hadley cells creates trade wind that passes in the tropic region,controlling the low latitude weather patterns.

The air mass that rises in the equatorial region forces the rising air to move towards the pole.As the air rises, it creates low pressure in the equatorial region and when the air travels to the poles, the air is getting cod and descends at 30°which creates high pressure area.These descending air then comes to the equator and thus the loop of Hadley cell become closes.

The pole ward movement  of the trade air that flows in the upper part of troposphere deviates from east to west.
