Climate Regulators: The Role of Boundary Currents

Along the eastern and western edges of every major ocean basin, currents behave very differently from each other, and those differences have enormous consequences for regional climates. Boundary currents explained covers the...

Questions: 20 | Attempts: 14 | Last updated: Mar 3, 2026

Sample Question 1
How are boundary currents primarily defined in the context of ocean gyres?

Currents that flow parallel to continental coastlines

Currents that only exist in the deep ocean

Currents that move exclusively at the equator

Currents caused by the moon's gravity

Currents that flow only in the center of the ocean

Sample Question 2
Western boundary currents are generally faster, deeper, and narrower than eastern boundary currents.

True

False

Sample Question 3
Which of the following are characteristics typically associated with Western boundary currents like the Gulf Stream?

High velocity (often > 2 m/s)

Transport of warm tropical water

Narrow width (under 100 km)

High nutrient content via upwelling

Shallow depth (less than 100 m)
