Question

large bodies of water do not quickly fluctuate in temperature. why? water is a solvent. water has a high heat capacity. water acts as a buffer. water is non-polar.

Explanation:

High heat capacity means water absorbs/releases much heat to change temperature. Large water bodies need lots of energy to warm/cool, so temp fluctuates slowly. Other options: solvent (dissolving, not temp), buffer (pH, not temp), water is polar (not non - polar).

Answer:

B. Water has a high heat capacity.
