Question

The following map of the Gulf of Mexico shows reported sightings of whale sharks. What explanation best describes why the highest reported sightings occur near the mouth of the Mississippi River?

A map of the Gulf of Mexico displaying reported sightings of whale sharks in the region. The map is shaded to indicate various numbers of whale shark sightings. The lightest gray shading indicates one to two whale sharks and can be found spread out along the coastline surrounding the Gulf of Mexico. The next shade of gray indicates three to five whale sharks. This shade of gray can also be found spread out along the coastline surrounding the Gulf of Mexico. The next darker shade of gray indicates six to eleven whale sharks and is primarily concentrated closer to the area where the Mississippi River meets the Gulf of Mexico. The very dark gray indicates eleven to fifteen whale sharks and is concentrated toward the region where the Mississippi River meets the Gulf of Mexico. The darkest shaded area, which is black, has the greatest concentration near the region where the Mississippi River meets the Gulf of Mexico.
