Document Summary
The nature of seawater, the hydrologic cycle, and global climate. Area of low pressure (l) warm, humid air; rainy weather: rising humid air, precipitation > evaporation. Area of high pressure (h) dry, cold air: sinking dry air, evaporation > precipitation. Convergence of ne trade winds and the se trade winds near the equator is called the intertropical convergence zone (itcz) 3 convection cells in each hemisphere, defined by alternating low and. High atmospheric pressure determine areas of vegetation on earth: polar cell, ferrel cell, hadley cell. Earth is a spinning planet: speed at equator = ~1000 mph, north pole isn"t moving at all 0 mph. Latitude on earth approximate distance around earth period. Consequences in change of velocity : earth is rotating differently depending on standpoint, merry-go-round example although the ball between two people on the device is thrown straight, it is curved in different directions. Earth rotates counterclockwise at the north pole: deflects to the right.
