What is Upwelling?
{{Use dmy dates|date=August 2021}} [[File:Upwelling2.jpg|thumb|Process of upwelling]] '''''Upwelling''''' is a rise of water from deep cold water towards the [[ocean]] surface. Upwelling occurs in the open ocean and along [[Coast|coastlines]]. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.<ref>{{Cite web|title=What is upwelling?|url=https://oceanservice.noaa.gov/facts/upwelling.html|access-date=5 August 2021|website=NOAA Office of Ocean Exploration and Research|language=EN-US}}</ref> == References == {{reflist}} [[Category:Oceanography]] {{stub}}
