Consider the following statements: 1. The annual range of temperature is greater in the Pacific Ocean than that in the Atlantic Ocean. 2. The annual range of temperature is greater in the Northern Hemisphere than that in the Southern Hemisphere. Which of the statements given above is/are correct?
- A1 only
- B2 onlyCorrect
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Statement 1 is incorrect. The annual range of temperature is generally greater in the Atlantic Ocean than in the Pacific Ocean. This is because the Atlantic Ocean is narrower and more influenced by surrounding landmasses, which heat up and cool down more rapidly than water. The vast Pacific Ocean, being much larger, tends to have a more stable temperature regime.
Statement 2 is correct. The Northern Hemisphere has a significantly larger proportion of landmasses compared to the Southern Hemisphere, which is predominantly covered by oceans. Land heats and cools much faster and to a greater extent than water. This continental effect leads to much greater annual temperature variations in the Northern Hemisphere compared to the Southern Hemisphere, where the vast oceans moderate temperature changes.
Therefore, only statement 2 is correct.
