Question

In deep fresh water ponds, different layers of water with different temperatures are noticed. This is known as

• A. Thermal stratification
• B. Surface tension
• C. Water equilibrium
• D. Thermal equilibrium

Answer 1

The correct option is A Thermal stratification

The aquatic biome can be divided into $2$ basic regions, Fresh water and Marine Fresh water consists of Ponds and Rivers. Marine consists of oceans and estuaries. In every aquactic biome, the water can be thermally startified. Thermal stratification is the phenomenon in which lakes develop two discrete layers of water of different temperatures - warn on top(epilimnion) and cold below(hypolimion) The cold denser water is on the bottom and warmer less denser water is at the surface of the water body.

So the answer to the question of how layers of water with different temperature are noticed in deep fresh water ponds is option(A)- "Thermal Stratification".
