Question

Akeem is walking on the beach on a hot summer day.

The sand is very hot, so he runs and puts his feet in the
water, which is much cooler. Explain why the water is
cooler than the sand.

Answer 1

The sand is warmer than the water

Step-by-step explanation:

Its because the sand attracts heat to itself and the water doesn't attract as much heat so its cooler than the sand.

Answer 2

Sand in a beach is warmer than the water of the sea.

Step-by-step explanation:

Water absorbs less heat from the sun when compared with sand. Sand is darker and also is less reflective. Because of its darker nature, absorption of heat from the sun will be more. Due to its less reflective nature the sand wouldn’t be able to reflect off the sunlight.

But water is highly reflective and can reflect off a major portion of the sunlight falling on the sea. The sea is also deep and thus the heat spreads through a large volume unlike in the case of sand. Water also has the nature of constant movement unlike sand which is stable.

This factor also heats up sand more than water.
