What are the two major ocean currents?

The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.

What is the largest ocean current?

The Antarctic Circumpolar Current
The Antarctic Circumpolar Current is the only ocean current to circle the planet and the largest wind-driven current on Earth.

What are large ocean currents called?

gyres
A gyre is a large system of rotating ocean currents. Together, these larger and more permanent currents make up the systems of currents known as gyres. Wind, tides, and differences in temperature and salinity drive ocean currents.

What are the two types of currents?

There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.

What are the two types of ocean currents give example?

Ocean circulation derives its energy at the sea surface from two sources that define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, inducing a momentum exchange, and (2) thermohaline circulation driven by the variations in water density imposed at the sea surface by …

What are the main ocean currents?

There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).

What is the biggest current?

Antarctic Circumpolar Current
The Antarctic Circumpolar Current is the largest current in the world. ‘It’s been estimated that this current is 110–150 times larger than all the water flowing in all the rivers of the world,’ says Dr Mike Williams.

What are the 3 major currents present in the ocean?

There are five main gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre. These surface currents play an important role in moderating climate by transferring heat from the equator towards the poles.

What are the 5 major ocean currents?

The five major circulation patterns formed by the currents on this map are the world’s five major ocean gyres: North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific.

What are the 3 major types of currents present in the ocean?

Oceanic currents are driven by three main factors:

  • The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast.
  • Wind. Winds drive currents that are at or near the ocean’s surface.
  • Thermohaline circulation.
