Question

which open - ocean zone order shows decreasing temperature?
deep zone, transition zone, surface zone
surface zone, transition zone, deep zone
transition zone, surface zone, deep zone
surface zone, deep zone, transition zone

Explanation:

The surface zone is closest to the sun, so it has the highest temperature. The transition zone is in the middle, and the deep zone is the farthest from the sun (and has the least heat transfer from the surface), so it has the lowest temperature. So the order from highest to lowest (decreasing) temperature is surface zone, transition zone, deep zone.

Answer:

surface zone, transition zone, deep zone
