What is specific heat?
Specific heat of any substance is defined as the amount of heat needed to raise the temperature of one gram of the substance by one degree celsius.
Specific heat of the water is higher than the specific heat of land, so that high amount of energy is required by the water to raise their temperature. And water also gets more time to cool down, so that water will have the most consistent temperature as compared to the land.
