Question

Ocean circulation is the large-scale movement of water in the ocean. It involves the transport of heat through convection, which is the movement of heat through liquids and gases.

Which statement describes how convection moves heat in the ocean during non-El Niño (normal) years?

Convection moves heat toward the west.
Convection moves heat toward the east.
Convection moves heat toward the north.
Convection moves heat toward the south.

Answer 1

Convection moves heat toward the west.

Reason: In normal (non‑El Niño) years, easterly trade winds push warm surface water west across the equatorial Pacific, creating a warm pool in the western Pacific where strong convection (rising warm water/air) transports heat.
