Watersheds are important because the surface water features and stormwater runoff within a watershed ultimately drain to other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Everything upstream ends up downstream.
Answer:
Space Research
Explanation:
There are numerous experiments going on at all times on the International Space Station, the majority of which cannot be done on the Earth. This research can potentially provide the information needed to help humans travel to other planets, clues about the formation of the universe, and even have applications in medicine.
The correct answer is b: cattle on rangeland. A point source of pollution occurs from a single identifiable and usually spatially narrow source. These sources of pollution are usually relatively easily to quantify and manage. In contrast, a non-point source of pollution, such as cattle on rangeland or irrigated agriculture, is variable on both spatial and temporal scales. These sources of pollution are difficult to quantify and manage.
