Question

Give reason.

With increasing depth, the temperature of sea water decreases to a certain limit.

Answer 1

• While most of the sun's rays radiate back from the surface of the sea, some of them penetrate to certain depths in the water.
• As a result, the intensity of the sun's rays decreases with increasing depth.
• Temperature decreases up to 2000m depth. In this way, with increasing depth, the temperature of the seawater decreases to a certain limit.
