Detailed explanation-1: -Thermal stratification occurs when two types of steam with different temperatures come into contact. Their temperature difference causes the colder and heavier water to settle at the bottom of the pipe while allowing the warmer and lighter water to float over the colder water.

Detailed explanation-2: -The phenomena of a sudden change in temperature at certain depths in a lake or pond is known as Thermal Stratification. Thermal stratification is when bodies of water “divide” into distinct layers of density due to different temperatures.

Detailed explanation-3: -This stratification is a natural occurrence, in any static body of water. It occurs when the surface layer of water, warmed by the sun, becomes less dense than the water underneath it. The surface layer remains on top and the lower layer, deprived of surface contact and insulated from the sun, continues to get colder.

Detailed explanation-4: -During the winter season, the ice cover forms on the surface and in such ice-bound lakes there exists an inverse stratification of water temperature, with the coldest water (ice) at the surface and the warmest water (4°C) on the bottom.

Detailed explanation-5: -Temperature and dissolved substances contribute to density differences in water. The atmosphere imposes a temperature signal on the lake surface. As a result, thermal stratification can be established during the warm season if a lake is sufficiently deep.
