Final answer:
Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature because water has a high heat capacity and requires a large amount of energy to change its temperature. This property of water allows it to stabilize temperatures, resulting in milder climates near large bodies of water.
Step-by-step explanation:
The reason that large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature is because water has a high heat capacity and requires a large amount of energy to change its temperature. This means that it takes a long time for water to heat up or cool down. For example, water can absorb a tremendous amount of energy with very little resulting temperature change. This property of water allows it to stabilize temperatures, which is why climates closer to large bodies of water are generally milder than landlocked climates.
