Which feature of water allows sheets of ice to form on the surface of lakes, thereby insulating the water below and protecting aquatic organisms during winter?
A) Water has surface tension.
B) Water is an excellent solvent.
C) Water has cohesion.
D) Evaporation requires energy.
E) Water is less dense when solid.
Surface Tension
The elastic tendency of a fluid's surface that allows it to resist an external force, due to intermolecular forces.
Solvent
Liquid in which other substances dissolve.
Cohesion
The force that holds molecules of the same substance together, such as water molecules in a drop of water.

Final Answer :
E
Explanation :
Water is less dense when it is solid, causing it to float on top of denser liquid water. This allows sheets of ice to form on the surface of lakes, which forms an insulating layer and helps protect aquatic organisms during the winter.
