Solution
The correct option is C Both 1 and 2
Explanation:
Statement 1 is correct: Walker circulation is longitudinal (east-west) circulation across the equatorial Pacific.
Statement 2 is correct: It is driven by temperature and pressure gradients. The areas of low-pressure form over the warmer western Pacific and areas of high-pressure form over the cooler eastern pacific waters. Winds near the equator flow from areas of high pressure to low pressure, and so the near-surface winds cross the Pacific move from east to west as part of the trade winds.
