Earth's Ocean Systems

The process of upwelling occurs as a result of

• warm, less-dense deep water that floats to the surface.
• cool, dense surface water that sinks and pushes deep water up.
• surface waves that mix surface and deep water
• sunlight that warms deep water that rises to the surface.
