Consider the following statements:
- 1Hadley cells are key to understanding the wind patterns of Earth.
- 2Hadley cells are formed because the Equator is heated more strongly by the Sun than other places, creating thermal circulations. With regard to the statements given above, which of the following is correct?
General KnowledgeGeography
- ABoth the statements are correct and statement 2 is the correct explanation of statement 1.
- BBoth the statements are correct, but statement 2 is not the correct explanation of statement 1.
- CStatement 1 is correct, but statement 2 is false.
- DStatement 1 is false, but statement 2 is correct.
Explanation
Hadley cells are the tropical atmospheric circulation cells central to understanding Earth's wind patterns, including the trade winds — statement 1 is true. They exist because the equator receives more intense solar heating than higher latitudes, driving warm air to rise at the equator and sink in the subtropics — statement 2 is true and is precisely the mechanism that explains statement 1. Hence option A is correct.
