When at the beach, why is the sand much warmer than the water?

• The water has a larger specific heat when compared to the sand.

• The sand has a larger specific heat when compared to the water.

• The sun doesn't hit the water so it does not warm up.

Answer explanation

The water has a larger specific heat compared to sand, meaning it requires more energy to increase its temperature. Therefore, while both are exposed to the sun, the sand heats up more quickly than the water.
