Answer:

Based on the solar light that enters the oceans and river

Explanation:

  • River ecosystem of a couple of both biotic and abiotic components among the plants and animals involving there physical and chemical properties. As the flow of water is unidirectional, it's in state of continuous physical change and has a high degree of spatial and temporal heterogeneity.
  • River sources are small, and in the areas of mountain streams, are steep and erosional. In temperate environments, overhead tree canopy conditions result in cool, well-oxygenated streams.  
  • All sorts of communities like coastal, estuaries, reefs and deep-sea trenches like Mariana trench which has no sunlight has a distinct type of community.

liberstina [14]
The salt will wash into the rivers and eventually the ocean. Too much salt in a freshwater system can be deadly to the wildlife. Ultimately, it will end up in the ocean, where it will have negligible impact. The real damage will be to any river systems it's washed into.

Shania is trying to determine the oldest geologic unit on this map. Why is she unable to do so?
Anna [14]

B. There is no key on the map

Explanation:

Shania would be unable to determine the oldest formation because there is no key on the map. The map does not contain the proper details to be used to infer age relationships among the formations.

  • A map presents a three dimensional world on two dimensional paper or surface.
  • To infer relative ages, a cross section from the two dimensional representation is the most desired.
  • From the cross section, the third dimension can carefully be studied and ages inferred.
  • There is little to no way we can infer relative age relationship on this surface.
  • To do that, we would require a key. Most times, the key shows the stratigraphic column which puts rocks in their correct ages.
  • Most keys are arranged with formations from the oldest at the bottom and the youngest on top.
  • Since this map lacks a key, direction, scale and other map elements, it would not be possible to infer relative ages of the rock.
