In ________, El-Nino gets established.

_________ is an example of Jet streams.

• Earth has four primary jet streams:
• Two polar jet streams, near the north and south poles.
• And two subtropical jet streams closer to the equator.

________is a warm ocean current.

• The surface waters of the Kuroshio Current are warm and salty.
• This is because the Kuroshio starts in the tropics where the westward flowing North Equatorial Current reaches the western boundary of the North Pacific.
• Peruvian current, is a cold, low-salinity ocean current that flows north along the western coast of South America.
• The Labrador current is a cold ocean current that flows from the Arctic Ocean southward along the coast of Labrador and Newfoundland.

The main causes of sea-level rise is ___________.

The ocean currents transport heat _____________.

__________are the large whirls of water within ocean basins.

• A gyre is a large system of rotating ocean currents.

Deep-ocean circulation currents are described as ____________ circulation.

____________is the cause of Coriolis Effect.

• The Coriolis effect affects the wind by deflecting its path to the right in the Northern hemisphere and the left in the Southern hemisphere.

The boundary between the land and the sea can be defined by the term ___________.

___________________ is not a major oceanic gyre.

The ‘West Wind Drift’ belongs to___________.

• Antarctic Circumpolar Current or West Wind Drift is the largest and most important ocean current in the southern hemisphere.

Other than wind, ______________is the most important factor that affects the movement of ocean water at the surface.

• Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind , Coriolis Effect and water density. 
• The Coriolis effect is strongest near the poles and is absent at the equator.

The Westerlies are__________.

• Westerlies are the Permanent winds that blow in the middle latitudes.
• The winds that change their direction with onsets of different seasons are called seasonal winds.
• Variable winds are those winds which blow in a small area and are related to the pressure systems.
• Mesoscale winds are better known as local winds or regional winds. These wind channels extend over long distances around the Earth.

Ocean currents can be triggered by ______________.

• Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms.

Ocean currents have_____________.

• By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate.

______ is defined as a movement of ocean water with a usual pattern.
