The same amount of air occupies more space when it heats up than when it is cold. (Answer: True. Quickly memorize the terms, phrases and much more. As a result of this uneven heating, the earth surfaces will vary a lot in temperature. True. The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures). D) When air moves from low pressure to high pressure it is called wind. Skin adjusts easily to changes in pressure, but the cavities within the body, such as the lungs, ears and sinuses, do not adjust automatically.
