Document Summary
3: how do we define freshwater (vs. saltwater)? o. Endanger the environment: be able to describe the hydrologic cycle. Surface water, because it does not get filtered. The sudden rise in elevation from hitting an upward slope of a mountain, which is why rockies get so much snow. The effect of it driving upward, facilitates the precipitation to occur. Transpiration and precipitation creates water vapor which is purified precipitant. As the water percolates through the soil, debris and bacteria are filtered out: what are two types of water discharge, and how does this relate to surface. Seep water flows out over a wide area. Spring water exists in a significant flow from a relatively small opening. Seeps and springs feed streams like lakes and rivers. Wastes are inevitably introduced in to water cycle. Smoke and fumes are exhausted or evaporated into the air and will come back down as contaminated precipitation. Agriculture: name the two consequences of overdrawing surface waters.
