What are the ocean currents?
Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.
What are ocean currents Ncert?
Ocean currents are the continuous flow of huge amount of water in a definite direction while the waves are the horizontal motion of water. Water moves ahead from one place to another through ocean currents while the water in the waves does not move, but the wave trains move ahead.
What are ocean currents 12?
Ans. An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water. The movement of ocean water is continuous and this movement of ocean water is broadly categorized into three types: waves, tides and currents.
What are ocean currents Toppr?
Ocean currents are the continuous flow of sea water from one direction to another. They can be classified as warm currents and cold currents. Warm currents are the currents that flow from the tropical or subtropical regions towards the polar or sub polar regions.
Why is ocean current?
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. Currents are cohesive streams of seawater that circulate through the ocean.
What are ocean currents give examples?
Ocean currents are channels of water moving in a particular direction in the oceans. The ocean currents are of two types – the warm currents and the cold currents. The warm currents flow from the equatorial region towards the poles. The cold currents flow from the poles to towards the equatorial regions.
What is ocean currents and its types?
They’re primarily driven by winds and by seawater density, although many other factors including the shape and configuration of the ocean basin they flow through influence them. 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 ocean current one word answer?
Ocean currents are streams of water flowing constantly on the ocean surface in definite directions.
What is ocean current answer in one sentence?
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.
What are ocean current 7 answers?
Ocean currents are streams of water flowing constantly on the ocean surface in definite directions. Ocean currents may be warm or cold. The Labrador Ocean current is cold current while the Gulf Stream is a warm current. The areas where the warm and cold currents meet provide the best fishing grounds of the world.
