Why is ocean climate (and the entirety of Earth, for that matter) divided into latitude parallel zones that become progressively colder from equator to pole?
a) Winds are stronger at higher latitudes, so cooling is greater at higher latitudes.
b) Precipitation and cloud cover increase with latitude, causing higher latitudes to be cooler.
c) Greater amounts of ice occur at higher latitudes, making it cooler at higher latitudes.
d) Cold ocean deep water returns to the surface at high latitudes, causing cooling.
e) The average solar radiation (sunlight) striking the surface declines from equator to poles.
Question 2

b) Assessing ecosystem health
