Distinguish between upwelling and downwelling
What will be an ideal response?
Upwelling is the upward vertical movement of cold, nutrient-rich, and oxygen-rich water from beneath the pycnocline toward the ocean surface. Downwelling is the movement of warm, nutrient-depleted, and oxygen-depleted water from the ocean surface downward. Upwelling is associated with highly productive areas of the ocean, while downwelling is associated with low primary production.
