Question: What Is The Difference Between A Surface Current And A Deep Ocean Current?

What are two major drivers of surface ocean current and deep ocean current?

These currents are on the ocean’s surface and in its depths, flowing both locally and globally.

Winds, water density, and tides all drive ocean currents.

Coastal and sea floor features influence their location, direction, and speed.

Earth’s rotation results in the Coriolis effect which also influences ocean currents..

What are the 3 types of ocean currents?

Two types of ocean circulationEquatorial currents. At the Equator the currents are for the most part directed toward the west, the North Equatorial Current in the Northern Hemisphere and the South Equatorial Current in the Southern Hemisphere. … The subtropical gyres. The subtropical gyres are anticyclonic circulation features. … The subpolar gyres.

What are the two main factors that affect deep ocean currents?

Unlike surface currents, which are driven by interactions with sun and wind, deep currents are caused by the interaction between temperature and water density. The higher the salt content of water, the more dense it is. Dense water is heavier than less dense water, and thus will sink because of gravity.

What are ocean surface currents?

The water at the ocean surface is moved primarily by winds that blow in certain patterns because of the Earth’s spin and the Coriolis Effect. Winds are able to move the top 400 meters of the ocean creating surface ocean currents. Surface ocean currents form large circular patterns called gyres.

What are the major surface currents?

Surface currents are created by three things: global wind patterns….Global Wind Patternstrade winds: east to west between the Equator and 30oN and 30oS.westerlies: west to east in the middle latitudes.polar easterlies: east to west between 50o and 60o north and south of the Equator and the north and south pole.

Is the Gulf Stream fast or slow?

The average speed of the Gulf Stream, however, is four miles per hour (6.4 kilometers per hour). The current slows to a speed of about one mile per hour (1.6 kilometers per hour) as it widens to the north.

How does the Gulf Stream affect people today?

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.

What are the 2 types of ocean currents?

There are two type of Ocean Currents:Surface Currents–Surface Circulation.Deep Water Currents–Thermohaline Circulation.Primary Forces–start the water moving.The primary forces are:Secondary Forces–influence where the currents flow.Solar heating cause water to expand.More items…

What are the 2 types of currents?

Direct and Alternating Current There are two different types of current in widespread use today. They are direct current, abbreviated DC, and alternating current, abbreviated AC. In a direct current, the electrons flow in one direction.

What is the current in the ocean called?

1. 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. These are called “tidal currents.” Tidal currents change in a very regular pattern and can be predicted for future dates.

Which is the current of Pacific Ocean?

North Pacific CurrentThe North Pacific Current (sometimes referred to as the North Pacific Drift) is a slow warm water current that flows west-to-east between 30 and 50 degrees north in the Pacific Ocean. The current forms the southern part of the North Pacific Subpolar Gyre and the northern part of the North Pacific Subtropical Gyre.

What would happen if the Gulf Stream stopped?

Well, it would stop bringing warm waters to those areas. Western Europe would get plunged into a deep freeze. … Normally, sea levels on the U.S. coast are lower compared to those on the coasts of Europe. That’s because the Gulf Stream is warmer when it gets to Europe.

Is the Gulf Stream a deep or surface current?

The Gulf Stream is typically 100 kilometres (62 mi) wide and 800 metres (2,600 ft) to 1,200 metres (3,900 ft) deep. The current velocity is fastest near the surface, with the maximum speed typically about 2.5 metres per second (5.6 mph).

What are the 5 major ocean currents?

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.

What causes deep ocean current?

Deep ocean currents (also known as Thermohaline Circulation) are caused by: … The sinking and transport of large masses of cool water gives rise to the thermohaline circulation, which is driven by density gradients due to variations in temperature and salinity.
