Upwelling brings those lost/sunk nutrients back to the surface, which creates "blooms" of algae and zooplankton, which feed on those nutrients. These blooms then become feeding grounds for plankton feeders, then fish, etc, sustaining ocean life that lives near the surface.

Why is upwelling important for sea life?
Because the deep water brought to the surface is often rich in nutrients, coastal upwelling supports the growth of seaweed and plankton. These, in turn, provide food for fish, marine mammals, and birds. ... Upwelling affects the movement of animal life in the area.
Why is upwelling important quizlet?
Upwelling is important because the nutrients that are brought to the surface support the growth of phytoplankton and zooplankton, which supports other life.
What is the importance of upwelling and downwelling?
Upwelling and downwelling describe mass movements of the ocean, which affect both surface and deep currents. These movements are essential in stirring the ocean, delivering oxygen to depth, distributing heat, and bringing nutrients to the surface.
What is an important effect of coastal upwelling quizlet?
Coastal upwelling occurs in areas where winds blow towards to equator and parallel to the coast. Upwelling brings greater concentrations of dissolved nutrients to the ocean surface, thus promoting the growth of plankton, which in turn support extensive populations of fish and other marine organisms.
Why are Downwellings important for marine environments?
Currents also are a major factor in ocean ecosystems. Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life. ... When currents upwell, or flow up to the surface from beneath, they sweep vital nutrients back to where they're needed most.
Why is upwelling important to humans?
Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.
How do ocean circulations and seawater movements affect marine life?
By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. They carry nutrients and food to organisms that live permanently attached in one place, and carry reproductive cells and ocean life to new places.
How does upwelling occur in the ocean?
Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling. ... Major upwelling areas along the world's coasts are highlighted in red.
Where does upwelling occur in the ocean?
Upwelling is most common along the west coast of continents (eastern sides of ocean basins). In the Northern Hemisphere, upwelling occurs along west coasts (e.g., coasts of California, Northwest Africa) when winds blow from the north (causing Ekman transport of surface water away from the shore).
How could increase sea surface temperature affect the great ocean conveyor Why is this important?
Rising temperatures may trigger events that could not only slow the supply of tropical water flowing north, it could disrupt the entire ocean circulation pattern. ... Water cycles from surface currents to deepwater currents then back to the surface again in what scientists liken to a giant conveyor belt.
What are the 3 major places where upwelling is common in the ocean?
Worldwide, there are five major coastal currents associated with upwelling areas: the Canary Current (off Northwest Africa), the Benguela Current (off southern Africa), the California Current (off California and Oregon), the Humboldt Current (off Peru and Chile), and the Somali Current (off Somalia and Oman).
How does upwelling affect the weather of a coastal region?
How does upwelling affect the weather of a coastal region? A. The warm surface water results in moist air and more rainfall.
What is the main reason mountaintops are so cold quizlet?
What is the main reason mountaintops are so cold? Mountaintops are above much of the greenhouse gas in the atmosphere. Why isn't Earth's atmosphere mostly hydrogen? Light gases such as hydrogen move faster than heavier gases and escape from Earth's gravitational field.
When it comes to carbon the ocean is the great and it helps to regulate?
50 to 70 % of our oxygen comes from the ocean. That's more than all of the world's rainforests combined. The ocean is the #1 source of protein for more than a billion people. The ocean regulates our climate, absorbs carbon dioxide, holds 97% of Earth's water, and supports the greatest abundance of life on our planet.
Which of the following can result in eustatic sea level rise?
Factors that affect eustatic sea level are large scale events: tectonic activity shrinking or growing the area of world oceans, a rise in temperatures causing thermal expansion of water, or large ice sheets melting and adding water to the oceans are the three most commonly discussed.
