which part of earth takes longer to heat up and cool down the land or the oceans

The oceans take longer to heat up and cool down compared to land. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a relatively high specific heat capacity compared to other substances, which means it can absorb and retain more heat energy before its temperature increases. Consequently, it takes a longer time for the oceans to heat up and cool down compared to land.
