Question

1. what is erosion? why is it harmful to the chesapeake bay watershed? erosion in nature things like rocks, water, and many more stuff moves. it can increase floods. 6. describe the importance of wetlands and estuaries. 7. salinity is the amount of salt dissolved in water. higher salinity means more salt is present. circle the part of the chesapeake bay that has the lowest salinity. 8. explain how sediment (soil, sand, and silt) enters the rivers and streams in

Explanation:

1. Erosion is the process by which natural forces like water, wind, or ice wear away rocks, soil, and other earth - materials. In the Chesapeake Bay Watershed, it is harmful because it can increase sedimentation in the bay, which can smother aquatic life, reduce water clarity, and disrupt habitats. It can also contribute to flooding by reducing the capacity of waterways to carry water.
2. Wetlands and estuaries are important as they act as natural filters, improving water quality by trapping sediment and pollutants. They also provide habitats for a wide variety of plant and animal species, support biodiversity, and can help protect against storm surges and erosion.
3. The part of the Chesapeake Bay closest to the freshwater sources (such as the mouths of major rivers) has the lowest salinity because the freshwater dilutes the salt - water.

Answer:

1. Erosion is the wearing away of earth - materials by natural forces. It is harmful to the Chesapeake Bay Watershed as it causes sedimentation, disrupts habitats, and increases flood risk.
2. Wetlands and estuaries filter water, support biodiversity, and protect against storm surges and erosion.
3. The part of the Chesapeake Bay closest to major river mouths has the lowest salinity.
