Here's the breakdown:
* Water heats up and cools down slower than land: This means that if you have equal amounts of land and water exposed to the same amount of sunlight, the water will generally be cooler during the day and warmer at night. This is because water has a higher specific heat capacity, meaning it takes more energy to raise its temperature.
* Land can reach higher temperatures: While water heats up slower, it also reaches a lower maximum temperature. Land, on the other hand, can become significantly hotter in the sun. This is why deserts, which are mostly land, can experience extreme temperatures.
So, which is hotter?
* It depends on the context.
* During the day: Land will usually be hotter than water.
* At night: Water will usually be warmer than land.
* Overall: Water has a higher specific heat capacity, so it generally takes more energy to change its temperature, but land can reach higher peak temperatures.
