higher the altitude, the lower the atmospheric pressure. Lower pressure
in turn causes water to evaporate more quickly, and water actually
boils at a lower temperature. The percentage of oxygen in the air at two
miles (3.2 km.) is the same as at sea level (21%). However, the air
pressure is 30% lower at the higher altitude due to the fact that the
atmosphere is less dense--that is, the air molecules are farther apart.
The important effect of this decrease in pressure is this: in a given
volume of air, there are fewer molecules present. This is really just
another way of saying that the pressure is lower. This is called Boyle's
law.</span>
The construction and operation of dams in the Colorado River have multiple benefits that include having increased water for irrigation and domestic supply, generation of hydroelectric power energy, providing improved aquatic recreation and wildlife habitat, and flood control.
