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

Answer 1

The correct order showing decreasing temperature in the open-ocean zones is:

**surface zone, transition zone, deep zone.**

In this arrangement, the surface zone is the warmest, the transition zone (or thermocline) has a gradual decrease in temperature, and the deep zone is the coldest.
