1. Runoff may be produced when precipitation or snow melt adds water to the soil surface faster than it can be absorbed. In humid areas with greater vegetation cover, the water table may lie at the surface in low-lying areas or slope hollows, so that the soil there is saturated.
2. Deltas are similar to alluvial fans in shape, but are deposited in a different environment. Sediments that form deltas are transported in continuous flowing water. Delta deposits are found at the mouths of streams or rivers as they empty into lakes and oceans.
3. Marshes are nutrient-rich wetlands that support a variety of reeds and grasses, while swamps are defined by their ability to support woody plants and trees. Bogs are characterized by their poor soil and high peat content, while fens have less peat and more plant life than a bog.
4. Nitrogen and phosphorus are nutrients that are natural parts of aquatic ecosystems. Nitrogen is also the most abundant element in the air we breathe. Nitrogen and phosphorus support the growth of algae and aquatic plants, which provide food and habitat for fish, shellfish and smaller organisms that live in water.
