Question

Match the following:
1. Pycnocline
2. Thermocline
3. Halocline

I. Transition zone of rapidly changing seawater density between low density upper layer and high density deep seawater.
II. Transition layer between warmer mixed water at the ocean's surface and cooler deep water below.
III. An intermediate layer of oceanic water in which salinity increases more rapidly with depth than in the layers above and below it.

• A. a) 1-I, 2-II, 3-III
• B. b) 1-II, 2-III, 3-I
• C. c) 1-I, 2-III, 3-II
• D. d) 1-III, 2-II,3-I

Answer 1

The correct option is A a) 1-I, 2-II, 3-III

a)
Explanation:
Pycnocline-Transition zone of rapidly changing seawater density between low density upper layer and high density deep seawater
Thermocline-Transition layer between warmer mixed water at the ocean's surface and cooler deep water below.
Halocline-An intermediate layer of oceanic water in which salinity increases more rapidly with depth than in the layers above and below it
