Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?
A
Water is an acid.
B
Water is a versatile solvent.
C
Water has a high heat capacity.
D
Water acts as a buffer.
Explanation: 

Detailed explanation-1: -To summarize, large bodies of water tend to moderate the temperature of nearby land due to the high heat capacity of water. This high heat capacity results from both the higher specific heat of water and the mixing of heat throughout a greater depth over oceans.

Detailed explanation-2: -“A large body of water has a higher heat capacity than land, meaning it takes more energy to warm and cool the temperature of water.

Detailed explanation-3: -Answer and Explanation: Ocean temperatures remain fairly constant because water has a high specific heat. The specific heat of a substance refers to the amount of heat energy that needs to be supplied in order to raise the temperature a unit mass of that substance by a certain degree.

Detailed explanation-4: -Air pressure also affects evaporation. If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor. Storms are often high-pressure systems that prevent evaporation.

Detailed explanation-5: -Because water absorbs and releases heat at a rate much slower than land, air temperatures in areas near large bodies of water tend to have smaller fluctuations.
