What are deep-water currents caused by cold water sinking and pushing up warmer water?
density currents.
How do deep currents move in an ocean?
The ocean currents known since antiquity are called surface currents. Though these are invaluable to shipping, they are superficial and occupy only a small fraction of the ocean's waters. The majority of the ocean's currents take the form of a temperature- and salinity-driven "conveyor belt" that slowly churns water within the abyssal depths. These loops of water circulation are called deep currents.
What is the difference between deep ocean currents and surface currents?
Deep ocean currents are in the depths of the oceans. Surface current are at the surface, not deep down. Deep ocean currents bring vitamins and nutrients to the shore, surface currents do not. Deep ocean currents are caused by salinity and temperature differences. Surface currents are cause by the force and impact of the wind.
Describe the two steps of upwelling?
Upwelling is water raising from deep in the ocean to the surface. It can be caused by wind ar density currents.
What factors are involved in causing deep ocean currents?
Temperature is what creates ocean gyres, which are large ocean currents. when the water heats up in the south it moves upward to the north. When the water is up north it gets cooled and goes down to the south again.
What makes up deep water regions of marine biomes receiving no sunlight?
Aphotic zone
What are convection currents in earths mantle?
the heat makes it rise up
Which current is water moving from place to place near or at the top of the sea?
With water or oceanic currents, the currents which move close to the surface of the sea are called surface currents. In such currents, wind acts on the water and the water piles up to form strong movement forces.
What causes salt water to rust a nail?
The oxygen in the water. This is true for salt water and fresh water. The salt makes the water electrically conductive, allowing slight electric currents to form and speed up the oxidation of the iron.
What are surface currents powered by?
The sun causes currents in the ocean because it is warming the water in the ocean in the day while it is hot, and then in the night when the sun goes down, the ocean starts to cool. Since the air above the water is warmer than in the water, this causes the water to rise up to the warmth until it gets cooled by the night, or from rain. This is what created movement and currents in the ocean from the sun.
How are currents that form in heated air similar to currents that form in heated water?
Currents that form in heated air are similar to currents that form in warm water because heated air goes up and cold air goes down creating convection currents.
What characteristic of a current is important in affecting climate?
the air in the atmosphere and the waters in our oceans circulate in known patterns in an effort to redistribute the energy. In the atmosphere, we end up with the prevailing wind bands in both hemispheres. In the oceans, we end up with both surface and deep water currents. It is the surface currents that have a marked effect on climate.
