Consider the following statements: 1. Ocean currents are slow-surface movement of water in the ocean. 2. Ocean currents assist in maintaining the Earth’s heat balance 3. Ocean currents are set in motion primarily by prevailing winds 4. Ocean currents are affected by the configuration of the ocean Which of these statements are correct?

Question

YESPYQ · Accepted Answer

Correct answer: 2, 3 and 4. Statement 1 is incorrect : While some ocean currents are slow-moving others like the Gulf Stream, can move swift- ly, reaching speeds of up to 5.6 miles per hour (9 kilometers per hour). Additionally, ocean currents are not limited to surface movements as there are also deep-water currents driv- en by differences in water density. Statement 2 is correct : Ocean currents play a significant role in maintaining the Earth’s heat balance by transporting warm wa- ter from the equator to the poles and cold water from the poles to the equator. This helps regulate global temperatures. Statement 3 is correct : Prevailing winds, such as the trade winds and westerlies, are a primary force driving ocean cur- rents. These winds create friction on the ocean’s surface, causing water to move. Statement 4 is correct : The configuration of the ocean, such as the shape of ocean basins, land masses, and coastlines, signifi- cantly influences the direction, speed, and path of ocean cur- rents. For example, the Gulf Stream is influenced by the shape of the North American coastli
