Large bodies of water maintain relatively constant temperatures compared to terrestrial locations. Why is this so, and how is this feature of water important for life?
What will be an ideal response?
Water is said to have a very high thermal capacity, which means that it takes the addition or the removal of enormous amounts of heat in order to change significantly the temperature of the body of water. This property of water is a direct result of the hydrogen bonding that occurs between water molecules. For example, when heat is added, much of that energy is absorbed by the hydrogen bonds, which vibrate with the added heat before they break resulting in a temperature rise of the water. Large bodies of water can absorb much more heat before there is a change in water temperature; therefore, large bodies of water create a stable environment where evolution can proceed.
