Specific heat is the amount of heat energy it takes to raise or lower the temperature of 1 gram of a substance by 1°Celsius. The specific heat of liquid water is 1 calorie per gram per 1 degree C (cal/g/°C). The specific heat of water is greater than that of dry soil, therefore water both absorbs and releases heat more slowly than land.
