Temperature of water under frozen lake
Web4 Jan 2008 · When the water is frozen over this causes problems with light penetration, just as in the deep waters, so photosynthesis is not the answer here. There are bacteria etc that are extremophiles and can survive in extremely deep water conditions. I wonder if there is something similar happening in the frozen reaches of your experimental wanderings. Web10 Oct 2016 · In order for water to freeze, it must reach a temperature of 0oC. This occurs at the surface of a lake, which is why it freezes. However, water, being a special molecule, expands when it freezes, rather than contracts, meaning that the ice on top of the lake is less dense than the water underneath it. This allows it to float on top of the water.

WebThe correct option is C. Conductivity of ice is low. The bottom of a lake do not freeze in severe winter. The reason is that ice is a poor conductor of heat hence once the surface is frozen no further heat is liberated or absorbed by water beneath ice. Therefore water below ice never freezes.

WebWhy Monitoring Matters. Many lakes greater than 12 feet in depth will stratify, forming layers of water with different temperature. This thermal stratification occurs due to differences in density between warm and cold waters, with cold water being denser and less viscous than warm water. Limnologists categorize the resulting layers from top to ... Web16 Jan 2024 · Warm water is less dense, so it floats on cooler water. Water is most dense at 39.2°F (4°C), before it freezes solid at 32°F (0°C). Solid water (ice) is less dense than liquid water—that’s why ice cubes float. This graph shows the density of H2O versus temperature.
