Chapter 3Surface Water: Rivers, Streams, and Lakes. Most of the earth 's water, about 97%, is the saltwater of the oceans. (See Figure 1.2 in Chapter 1.) By comparison, freshwater comprises only 3% of the earth's water, and surface water is only 0.3% of that 3%. Furthermore, rivers and lakes comprise 2% and 87%, respectively, of surface water.

Where Upwelling Occurs. Diverging surface waters occur where surface waters are moving away from an area on the ocean surface. • Equatorial upwelling occurs where SE trade wind blow across the equator (Figure 9.19); Ekman transport forces surface water movement to the south (south of the Equator), and to the north (north of the Equator).Fresh surface waters sustain ecological systems and provide habitat for many plant and animal species.
