2. Movement of cool ocean water to warmer parts is called cold ocean current.
3. Labrador current is one of the major warm currents.
4. Gulf Stream is one of the major cold ocean currents.

Q. Which of the following are different factors that affect the temperature distribution of the ocean?

2. Prevailing winds
3. Ocean current
4. Longitude

Q. Statement 1: Onshore winds drive warm surface water away from the coast and decrease ocean temperature.

Statement 2: Wind direction largely af­fects the horizontal distribution of ocean temperature.

Read the above given statements and select the option that is true.

2. Both the statements are correct.
3. The statement 1 is incorrect but the statement 2 is correct.
4. The statement 1 is correct but the statement 2 is incorrect.
