Concept:Hadley cells are large-scale atmospheric circulation patterns driven by differential solar heating, and they form the basis for understanding global wind patterns.
Explanation:The Equator receives more direct sunlight than other regions, causing intense heating.
This heat makes the air rise, creating a low-pressure zone at the Equator.
The rising air cools and moves toward higher latitudes, then sinks around
30∘ north and south, forming high-pressure zones.
This cycle of rising and sinking air creates a thermal circulation known as a Hadley cell.
The movement of air within Hadley cells directly produces the trade winds, westerlies, and other major wind belts.
Thus, statement 1 is correct: Hadley cells are key to understanding Earth's wind patterns.
Statement 2 correctly states that Hadley cells form because the Equator is heated more strongly, creating the thermal circulations described above.
Therefore, both statements are correct, and statement 2 provides the correct explanation for statement 1.
Answer:Option A. Both statements are correct and statement 2 is the correct explanation of statement 1.
