The ocean, air, and land heat up at different rates.
Water has a high specific heat capacity (4.18 J/gK)
Sand is lower (0.58 - 1.04 J/gK)
Air is 1.01 J/gK

Multiple Choice
If the specific heat capacity of water is about 4 times larger than sand, then...

Multiple Choice
7
Daytime Beach
Water has a higher specific heat than sand, it heats up slower. The sand has a lower heat capacity and heats up fast
8
Beach at Night
At night, the water cools off slower. The sand cools off faster. This is why the ocean may be warmer than the beach at night!
Try swimming at night... if you dare!
