What is it called when cold water rises from the bottom of the ocean?
However, the cold water doesn't always stay at the bottom of the ocean. Instead, it comes up at different places around the globe called upwelling. Since the ocean floor contains many nutrients important for survival, the cold water that rises to the surface brings these nutrients with it, attracting all forms of life.
What would cause cold water to rise to the surface?
Upwelling is a process in which currents bring deep, cold water to the surface of the ocean. Upwelling is a result of winds and the rotation of the Earth.
What is upwelling and downwelling?
Downwelling is where surface water is forced downwards, where it may deliver oxygen to deeper water. Downwelling leads to reduced productivity, as it extends the depth of the nutrient-limited layer. Upwelling occurs where surface currents are diverging, or moving away from each other.
What causes upwelling?
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.
What upwelling means?
Upwelling is a process in which deep, cold water rises toward the surface. This graphic shows how displaced surface waters are replaced by cold, nutrient-rich water that “wells up” from below.
What is the definition thermocline?
A thermocline is the transition layer between warmer mixed water at the ocean's surface and cooler deep water below.
What do you mean by thermocline?
A thermocline is the transition layer between the warmer mixed water at the surface and the cooler deep water below. It is relatively easy to tell when you have reached the thermocline in a body of water because there is a sudden change in temperature.
What are warm and cold ocean currents?
Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current's direction and speed depend on the shoreline and the ocean floor.
What is the meaning of downwelling?
Downwelling is the process of accumulation and sinking of higher density material beneath lower density material, such as cold or saline water beneath warmer or fresher water or cold air beneath warm air. It is the sinking limb of a convection cell.

What gyre means?
A gyre is a large system of rotating ocean currents. There are five major gyres, which are large systems of rotating ocean currents. The ocean churns up various types of currents. Together, these larger and more permanent currents make up the systems of currents known as gyres.
What is a thermocline layer?
A thermocline is the transition layer between warmer mixed water at the ocean's surface and cooler deep water below.
What is cold current called?
When cold ocean waters move towards warmer regions, it is called a cold ocean current. The Labrador currents are the major cold currents. Geography.
What happens when warm and cold ocean currents meet?
This is because air above the warm currents is warm which contains water vapour. When this warm current meet the cold current, the air above the cold current, causes the water vapour of the warm current to condense into tiny particles which form fog.

What is frumious?

What is thermocline and halocline?
A halocline is most commonly confused with a thermocline – a thermocline is an area within a body of water that marks a drastic change in temperature. A halocline can coincide with a thermocline and form a pycnocline. Haloclines are common in water-filled limestone caves near the ocean.
What is the halocline layer?
halocline, vertical zone in the oceanic water column in which salinity changes rapidly with depth, located below the well-mixed, uniformly saline surface water layer.
What is warm and cold ocean currents?
Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current's direction and speed depend on the shoreline and the ocean floor.
Why are currents called warm or cold?
Those currents that flow from the Equator towards the poles are warmer than the surrounding water and so they are called warm currents. The ocean currents that flow from the polar areas towards the Equator are cooler compared to the surrounding water, so they are called cold currents.
What are ocean currents describe warm and cold currents with example?
Warm currents: The current that originates near the equator and flows towards the poles is called a warm current. 2. Cold currents: The current that originates in the high latitudes and flows towards the equator is called a cold current.
What is surface water answer?
Oceans, streams , lakes , ponds, and other bodies of water found on the Earth's surface are considered surface water. This is in contrast to groundwater, which is found beneath the surface of the earth. Atmospheric water also exists. This includes water vapor in the air, such as clouds.
How does groundwater become surface water?
Groundwater and surface water are interconnected; groundwater becomes surface water when it discharges to surface water bodies. Most streams keep flowing during the dry summer months because groundwater discharges into them from the zone of saturation – this flow is called baseflow.
What does Gyre and Gimble mean?
“To gyre”: to go round and round like a gyroscope. “To gimble”: to make holes like a gimblet.
What is a Borogrove?
borogove (plural borogoves) A thin shabby-looking fictional bird with its feathers sticking out all round, something like a live mop, first introduced in the nonsense poem Jabberwocky.
What is a Hydrocline?
In oceanography, a halocline (from Greek hals, halos 'salt' and klinein 'to slope') is a cline, a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water.
What is halocline and thermocline?
The pycnocline encompasses both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth. Because density is a function of temperature and salinity, the pycnocline is a function of the thermocline and halocline.
What are the cold ocean currents?
List of Cold Currents

| Eastern Greenland Current | Arctic Ocean & North Atlantic Ocean |
| Benguela Current | South Atlantic Ocean |
| Falkland Current | South Atlantic Ocean |
| Northeast Monsoon Current | North Indian Ocean |

What called cold currents?
Think of cold currents as currents moving toward the Equator. These waters are colder than the water they are moving into. If you were swimming in the ocean whose temperature was 70 degrees F and you swam into a current whose temperature was 60 degrees F, the sensation would be cold.
What is surface water groundwater?
Surface water includes any freshwater that's sent into wetlands, stream systems, and lakes. On the other hand, groundwater exists in subterranean aquifers that are situated underground. Most groundwater is obtained from snowmelt and rainfall that gets into the bedrock via the surrounding soil.
