Final answer:
Land heats up and cools down more quickly than water because it has a lower specific heat capacity. Water requires more energy to change temperature, which makes coastal climates more moderate compared to inland climates due to the presence of large bodies of water such as oceans and lakes.
Step-by-step explanation:
Land surfaces cool and warm more quickly than water surfaces, and to lower and higher temperatures because of the specific heat capacities of land and water. The specific heat capacity of water is about five times more than that of sand or soil, which means it takes more energy to raise the temperature of water by one degree Celsius compared to land. Consequently, land heats up and cools down much faster than water. This difference in specific heat capacity is one reason coastal climates are more moderate than inland ones, as large bodies of water like oceans and lakes have a moderating effect on temperature, absorbing heat on hot days and releasing it on cool ones.
