What is lake stratification and turnover?

Lake turnover is the process of a lake's water turning over from top (epilimnion) to bottom (hypolimnion). During the summer, the epilimnion, or surface layer, is the warmest.

Also asked, what is the meaning of thermal stratification?

The thermal stratification of lakes refers to a change in the temperature at different depths in the lake, and is due to the change in water's density with temperature. Cold water is denser than warm water and the epilimnion generally consists of water that is not as dense as the water in the hypolimnion.

What is stratification in ponds?

yearly process known as thermal stratification. A pond that is thermally stratified simply means that there is a noticeable temperature gradient as the water get deeper. If your pond is stratified, you will notice the deeper water around your lower legs is noticeably colder than the surface water.

Why is the lake temperature stratified in the summer?

Because of this density-temperature relationship, many lakes in temperate climates tend to stratify, that is, they separate into distinct layers. In lakes of the upper Midwest and at higher elevations, the water near a lake's bottom will usually be at 4°C just before the lake's ice cover melts in the spring.
