What best describes the importance of upwelling to humans?

An upwelling is when a deep ocean current rises to the surface, bringing nutrients to the surface.


What cold currents near coastlines might indicate sites of upwelling?

Cold currents near coastlines often indicate the presence of upwelling. This is because upwelling brings cold, nutrient-rich waters from the ocean depths to the surface, leading to colder surface currents. Some examples of cold currents near coastlines that are associated with upwelling include the California Current, the Benguela Current, and the Canary Current.


How is a density current related to upwelling?

A density current can induce upwelling by displacing surface waters horizontally with denser, cooler water moving towards the surface. When the denser water displaces the surface water, it creates a vacuum that is filled by cold, nutrient-rich water from deeper layers. This process brings important nutrients to the surface waters, which can enhance biological productivity in the ocean.

Describe the two steps of upwelling?

Upwelling occurs when wind pushes surface ocean water away from the coastline, causing deeper, colder, nutrient-rich water to rise and replace it. This brings nutrients to the surface, fueling the growth of phytoplankton and supporting a productive marine ecosystem.
