Q. The Ocean currents transfer heat from ________
An ocean current is a continuous movement of ocean water from one place to another. Ocean currents are created by wind, water temperature, salt content, and the gravity of the moon. The current's direction and speed depend on the shoreline and the ocean floor. They can flow for thousands of miles and are found in all the major oceans of the world. One major example of an ocean current is the Gulf Stream in the Atlantic Ocean. Ocean currents can be found on the water surface and deeper down.
The surface ocean currents have a strong effect on Earth's climate. Areas near the equator receive more direct solar radiation than areas near the poles. However, these areas do not constantly get warmer and warmer, because the ocean currents and winds transport the heat from the lower latitudes near the equator to higher latitudes near the poles.
The type of heat transfer that develops ocean currents is known as Convection. In convection, heat is transferred through a fluid (such as water or air) when there is a difference in the temperature within the given fluid.
- One sea or ocean to another
- One coast to another
- The surface of the sea to greater depths
- Lower to higher latitudes
Answer: Lower to higher latitude.
The Ocean currents transfer heat from lower to higher latitude.

How do currents transfer heat in the ocean?
The surface ocean currents have a strong effect on Earth's climate. Areas near the equator receive more direct solar radiation than areas near the poles. However, these areas do not constantly get warmer and warmer, because the ocean currents and winds transport the heat from the lower latitudes near the equator to higher latitudes near the poles.
How do currents transfer heat in the ocean?
- radiation
- convection
- conduction
- evaporation
Answer: Convection
The type of heat transfer that develops ocean currents is known as Convection. In convection, heat is transferred through a fluid (such as water or air) when there is a difference in the temperature within the given fluid.
Ocean currents are located at the ocean surface and in deep water below 300 meters (984 feet). They can move water horizontally and vertically and occur on both local and global scales.
Energy is redistributed in the oceans by ocean currents. This is permanent or continuous movement of ocean water from one place to another. They can flow for thousands of kilometres and can result in warm water being transferred to high latitudes (The Poles) and cool water being transferred to low latitudes (the Equator and Tropics). Ocean currents can also determine the climates of continents.
Ocean currents are driven by a phenomenon known as “thermohaline circulation”. The thermo refers to the sun’s heat and the haline to the salt content. Both of these factors determine the density of ocean water. Colder water, and that with a higher salt content is much denser than warmer water with a lower salt content.
