Water has a higher specific heat capacity than land. Specific heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. It is expressed in joules per gram per degree Celsius (J/g°C) or calories per gram per degree Celsius (cal/g°C).
Water has a specific heat capacity of approximately 4.18 J/g°C (or 1 cal/g°C), which means it takes 4.18 joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius. Land, on the other hand, typically has a much lower specific heat capacity, which can vary depending on the composition of the land (such as soil, rock, or sand). However, in general, the specific heat capacity of land is significantly lower than that of water.
This difference in specific heat capacity between water and land is one of the reasons why coastal areas tend to have milder climates compared to inland areas. Water can absorb and store large amounts of heat energy, which results in slower temperature changes. In contrast, land heats up and cools down more quickly because it has a lower capacity to retain heat.
