What current is not affected by land?
Because no land barriers obstruct the prevailing current traveling between the southern tips of South America and Africa and the northern coast of Antarctica, the Antarctic Circumpolar Current consistently circles the globe in a west to east direction.
Which current encircles the entire earth without interruption?
Cards
| Term Ocean Currents | Definition Masses of ocean water that flow from one place to another |

| Term North Atlantic Current | Definition North Atlantic current, Canary Current, North Equatorial current, Gulf Stream |
| Term West Wind Drift | Definition The only current that completely encircles the Earth |
Which current flows completely around Earth?
The Antarctic Circumpolar Current (ACC) is the most important current in the Southern Ocean, and the only current that flows completely around the globe. The ACC, as it encircles the Antarctic continent, flows eastward through the southern portions of the Atlantic, Indian, and Pacific Oceans.
What are land currents?
Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins. Surface ocean currents. Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
Does land affect the ocean currents?
In addition to the Coriolis Effect, land masses or continents can influence ocean currents by causing them to be deflected from their original path. Surface currents have a considerable effect on the climate of areas along their path.
What is the most powerful ocean current?
The Antarctic Circumpolar Current
The Antarctic Circumpolar Current is the planet’s most powerful and arguably most important current. It is the only current to flow clear around the globe without being diverted by any landmass.
Where is the North Atlantic Current?
North Atlantic Current, also called North Atlantic Drift, part of a clockwise-setting ocean-current system in the North Atlantic Ocean, extending from southeast of the Grand Bank, off Newfoundland, Canada, to the Norwegian Sea, off northwestern Europe.
What is one effect of the Gulf Stream?
This strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in the summer than the other southeastern states. Since the Gulf Stream also extends toward Europe, it warms western European countries as well.
How does land affect surface currents?
Where is the Canary Current located?
The Canary Current is a wind-driven surface current that is part of the North Atlantic Gyre. This eastern boundary current branches south from the North Atlantic Current and flows southwest about as far as Senegal where it turns west and later joins the Atlantic North Equatorial Current.
Which currents flow in the Indian Ocean?
The Indian Ocean gyre is composed of two major currents: the South Equatorial Current, and the West Australian Current.
How does an interruption of a line affect the current?
Current interruption The voltage difference between the MOV voltage and the voltage source in the network forces the line current towards zero and the line current becomes eliminated. The voltage set up by the MOV typically is 1.5 times the rated voltage in the connected system.
How is the current interrupted in an AC circuit?
The line current in AC systems repeatedly, twice per cycle at fundamental frequency, pass through zero. At these instants no magnetic energy is stored in the inductance in the transmission system connected to the circuit breaker and current interruption at zero cross-over instants can be executed without problems.
Can a mechanical interrupter be used to interrupt a current?
Another option to execute current interruption, independent of externally created current zero-crossings, is offered by using a mechanical interrupter, which is assisted by auxiliary circuitry creating a current zero-crossing in the arc, while the contacts are separating.
