en.wikipedia.org/wiki/Stratification_(water)

Water stratification is when water masses with different properties - salinity , oxygenation , density , temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia. These layers are normally arranged according to density, with the least dense water masses sitting above the more dense ...

Water stratification is what happens when water displays different properties such as density, temperature, salinity, and oxygenation. These layers act as barriers that prevent the water from mixing. This is why salt water and fresh water do not mix.

en.wikipedia.org/wiki/Lake_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.

Stratification of Water The vertical distribution of water density in bodies of fresh or salt water is known as stratification and is characterized by the vertical density gradient. The greater the increase in density with depth and the greater the vertical gradient, the higher the stability of the stratification. When the vertical density gradient is ...

Thermal stratification is possible as water becomes less dense when heated, meaning water weighs less per unit volume. Therefore, warmer water will be lighter and colder water will be heavier. Due to this, there will always be a level of “self-induced” thermal stratification in a water storage.

Density Stratification In the spring, immediately after ice-out in temperate climates, the water column is cold and nearly isothermal with depth. The intense sunlight of spring is absorbed in the water column, which also heats up as the average daily temperature of the air increases.

I tried the “water stratification” with some tropical milkweed seeds… out of 10 seeds 6 sprouted within a week. Pretty good. I haven’t given up on the other 4 yet. I might try it with some other varieties when the proper time comes. Thanks for the tips.

Water Density. To understand lake stratification, we first must address the relationship between water density and temperature. Water is unique in that it is more dense as a liquid than a solid; therefore, ice floats.

Ocean Stratification. Lecture slides (powerpoint) Take away ideas: Water & Climate: The ocean extends over 70.8% of the earth's surface. The ocean holds 98% of the 1.4 billion cubic kilometers of water on the planet, divided within three major basins. The high capacity and density of water relative to the atmosphere, and the great amount of ...

Not all plant seeds are ready to sprout as soon as you put them in the soil. Some hard-shelled seeds need a bit more coaxing and some need a temperature change to trigger the end of dormancy. Scarification, cracking the hard outer shell, and stratification, fooling seeds into thinking they've been through winter, are two easy to do techniques that will save you a lot of frustration when ...
