UPSC 2021: 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?

In tropical latitudes the easterly trade-wind drift piles warm surface water westward, so the western margins of tropical oceans (e.g., Gulf Stream source, Kuroshio) are warmer than their eastern margins—making statement 1 correct. In mid-latitudes the westerlies push warm currents eastward (e.g., North Atlantic Drift, North Pacific Drift), warming the eastern sections of temperate oceans; statement 2 is therefore correct. Both statements hold. ([edukemy.com](https://edukemy.com/blog/upsc-prelims-2021-question-38/?utm_source=openai))
