The first statement is incorrect because the annual range of temperature in the Atlantic Ocean is greater than in the Pacific Ocean. This is due to the former`s smaller size and shallower depth compared to the latter, which results in quicker and greater temperature changes.

The second statement is correct. The Northern Hemisphere has a larger landmass than the Southern Hemisphere, and land heats and cools faster than water. As a result, temperature ranges tend to be larger in the Northern Hemisphere than the Southern Hemisphere.

Therefore, only the second statement is correct. Option 2 is the correct choice. Statements should be evaluated individually to understand each concept clearly.
