Which of these statements best describes the characteristic of water that impacts its role in moderating Earth's climate?

Water is a fluid with a high specific heat.

Explanation:

Specific heat is defined as the amount of heat energy measured in calories, that is required to change the temperature of one gram of a substance by one degree Celsius. Water has a very high specific heat of 4.184 Joules. This means that water does not get heated up or cooled easily.

This is important for earth's climate and the organisms in it as they are not subject to sudden and frequent temperature fluctuations.
