Deep Nutrients: The Power of Ocean Upwelling

Some of the most biologically productive regions of the ocean are not found in warm tropical waters but in places where cold, nutrient-rich water rises from the deep. Ocean upwelling explained covers how wind-driven surface...

Questions: 20 | Attempts: 11 | Last updated: Mar 3, 2026

Sample Question 1
What is the primary physical movement involved in the process of upwelling?

Deeper water rising to the surface

Surface water sinking to the bottom

Water moving only in horizontal circles

Evaporation of the ocean surface

Tides moving toward the shore

Sample Question 2
During ocean upwelling, the water that reaches the surface is typically much warmer than the water it replaces.

True

False

Sample Question 3
What role does the Coriolis effect play in coastal ocean upwelling?

It deflects surface water away from the coast

It makes the water spin in a tight circle

It heats the water as it rises

It stops the wind from blowing

It pulls the Moon closer to the Earth
