Which statement best describes an effect of the low density of frozen water in a lake?
Answers
Answer:
Water in a lake freezes from the bottom up, killing most aquatic organisms. When water in a lake freezes, it floats, providing insulation for organisms below.
Specific heat capacity and heat of vaporization of water. ... That means water expands when it freezes. ... and the slow- cooling water can release heat to nearby land during the night.
Water freezes from the top down—which allows ice to float—because of a strange quirk in how water's density behaves at falling temperatures. ... For example, a pocket of warm air rises and expands because it is less dense than the cooler air around it.
During the winter many aquatic organisms that live in our lakes hunker down, ... If water were most dense as a solid, lakes would freeze from the bottom up, eventually freezing solid.
Water is one of the few exceptions to this behavior. When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.

water removes thermal energy from surrounding land , causing the land to freeze . Water freezing on the top floats and provides insulation to the organisms living below
