Areas near oceans or large lakes tend to have more moderate climates than do areas far from large bodies of water. Which of these statements best explains this observation? a. Hydrogen and oxygen atoms share electrons in a water molecule.
b. Water has a very high specific heat.
c. Lakes and oceans contain dissolved solids.
d. Water produces buoyant forces.

B

Explanation: The specific heat of any particular substance is usually defined as the amount of heat energy that is required to raise a unit mass of the material by 1°C. The water has this high heat capacity as a result of which the water bodies such as oceans, seas, and lakes tend to become hot and cold at a much slower rate.
