At what degree both North and South does air begin to sink back to the surface? A. 30°
B. 45°
C. 50°
D. 60°

Explanation:

At 30° latitude (both north and south), the equatorial air has cooled and sinks, creating a high pressure zone and pushing the surface air away to the north or south.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
