Frequently Asked Questions...

explain the process by which sand is heated?

Best Answer...


A process of selective absorption of solar radiation.
As you might know the spectrum of the sun's energy encompasses ultraviolet skin damaging ionizing radiation,
visible light and infrared wavelengths. A sandy beach looks
quite dazzling on a sunny day, so we may conclude that sand
reflects light back. However the silicate minerals that make
up sand are constantly vibrating at the scale of nano meter crystal units, according to temperature of the air. These are
the right scale to be affected by infrared rays that strike the
near surface. These crystal units vibrate much more strongly
and conduct (transfer) their enhanced motion both to the air molecules that strike them and sand grains further down.
So eventually under the unrelenting gaze of Mr Sun. the beach
gets quite hot
