Question 139948 • PARTA - EOP: PGCPS BIOGEOCHEM CR (FALL2026) - 798113
Cool water is denser than warm water, so it can sink toward the ocean floor. As cool surface water moves away or sinks, warmer water can move in to replace it. Winds blowing parallel to a coast can also push surface water away from shore, allowing cool water from below to rise in a process called upwelling. The Coriolis effect deflects moving water; it does not cause warm and cold water to mix.
