Consider the following statements :
1. In the tropical zone, the western sections of the oceans are warmer than the eastern sections owing to the influence of trade winds.
2. In the temperate zone, westerlies make the eastern sections of oceans warmer than the western sections.
Which of the statements given above is/are correct?
Correct Answer: Option C
Explanation
1. Statement 1 is correct. In the tropical zone, the prevailing trade winds blow from east to west. These winds exert drag on the surface water, pushing warm surface ocean waters westward. This accumulation of warm water makes the western sections of the oceans generally warmer than the eastern sections. In the eastern sections, the offshore movement of surface water often leads to upwelling of colder, deeper water.
2. Statement 2 is correct. In the temperate zone (mid-latitudes), the prevailing westerlies blow from west to east. These winds drive surface ocean currents (like the North Atlantic Drift or North Pacific Current) eastward, transporting warmer waters towards the eastern sections of the oceans (western coasts of continents). This makes the eastern sections warmer than the western sections (eastern coasts of continents) at similar latitudes.
Therefore, both statements are correct.
