What Are The Two 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 are the two ocean currents?

There are two distinct current systems in the ocean—surface circulation, which stirs a relatively thin upper layer of the sea, and

deep circulation

, which sweeps along the deep-sea floor.

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 2 types of deep 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.

What are the main types of currents?

There are two types of currents,

surface currents and deep water currents

, that dictate how and where water will move.

Why do we have 2 types of current?

There are two different types of current in widespread use today. … In

a direct current, the electrons flow in one direction

. Batteries create a direct current because the electrons always flow from the ‘negative’ side to the ‘positive’ side. In a direct current, the electrons travel in one direction.

Which current is used in home?

Alternating current (AC)

electricity is the category of electricity usually used in homes and businesses. Direct current (DC) means the unidirectional stream of electric charge. Most of the digital electronics use DC.

What happens when two ocean currents meet?

Many boat/ship wrecks

happen where the two currents meet. This is one reason that area is known as the “Graveyard of the Atlantic”. The two currents can play a role in the weather patterns such as thick fog and large temperature differences which can enhance weather systems right off shore!

What are the 5 major ocean currents?

Ocean gyres are large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation. 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

.

Where are the strongest ocean currents?

The strongest and most renown surface ocean currents are

the Gulf Stream

, that travels from the Caribbean Sea, along the East coast of North America and across the Atlantic Ocean to Europe, and the Kuroshio Current in the North Pacific Ocean off the East coast of Asia.

Which current is the densest?

The densest deep water mass is formed in

the Weddell Sea of Antarctica

, and becomes the Antarctic Bottom Water (AABW). Similar processes in the North Atlantic produce the North Atlantic Deep Water (NADW) in the Greenland Sea (Figure 9.8.

What’s a deep current?

Deep currents, also known as thermohaline circulation,

result from differences in water density

. These currents occur when cold, dense water at the poles sinks. Surface water flows to replace sinking water, causing a conveyor belt-like effect of water circulating around the globe on a 1000-year journey.

What is the ocean current called?

Thermohaline circulation, also

known as the ocean’s conveyor belt, refers to the deep ocean density-driven ocean basin currents. … These currents, which flow under the surface of the ocean and are thus hidden from immediate detection, are called submarine rivers.

What are the 3 main types of currents?

• 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.

What are air currents?

Air currents are

winds that move in a riverlike flow in a certain direction

. Thermal updrafts are gentle currents caused by warm air rising. Birds like eagles or California condors often ride these updrafts high into the sky. Jet streams are rapidly moving cold currents that circle the Earth high in the atmosphere.

What 3 things affect surface currents?

Surface currents are controlled by three factors:

global winds, the Coriolis effect, and continental deflections

. surface create surface currents in the ocean. Different winds cause currents to flow in different directions. objects from a straight path due to the Earth’s rotation.
