With reference to Ocean Currents, consider the following statements: 1. They represent a regular volume of water in a definite path and direction. 2. Heating by solar energy is a secondary force that influences the currents. 3. Coriolis force is a primary force that initiates the movement of water. Which of the statements given above is/are correct?

Correct Option The correct option is 1 and 3 only. Explanation Ocean currents are continuous and directed movements of ocean water along a defined path. The movement of ocean currents is controlled by primary forces such as wind, solar heating, gravity, and the Coriolis force. Solar heating is a primary force because differential heating creates expansion, slope, and pressure differences in ocean water. - Statement 1: Correct. Ocean currents represent a regular movement of a large volume of ocean water in a definite path and direction. - Statement 2: Incorrect. Heating by solar energy is not a secondary force; it is a primary force influencing ocean currents by causing differential heating and water movement. - Statement 3: Correct. The Coriolis force is treated as a primary force affecting ocean currents, as it deflects moving water to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Therefore, statements 1 and 3 are correct. Key Takeaway: Solar heating and Coriolis force are primary forces associated with ocean currents, while Coriolis force mainly determines the direction of moving water.

Solution

Correct Option

The correct option is 1 and 3 only.

Explanation

Ocean currents are continuous and directed movements of ocean water along a defined path.

The movement of ocean currents is controlled by primary forces such as wind, solar heating, gravity, and the Coriolis force. Solar heating is a primary force because differential heating creates expansion, slope, and pressure differences in ocean water.

Statement 1: Correct. Ocean currents represent a regular movement of a large volume of ocean water in a definite path and direction.
Statement 2: Incorrect. Heating by solar energy is not a secondary force; it is a primary force influencing ocean currents by causing differential heating and water movement.
Statement 3: Correct. The Coriolis force is treated as a primary force affecting ocean currents, as it deflects moving water to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Therefore, statements 1 and 3 are correct.

Key Takeaway: Solar heating and Coriolis force are primary forces associated with ocean currents, while Coriolis force mainly determines the direction of moving water.
