What types of beaches are there?

There are many different types of beaches in the world. There are sandy beaches, rocky and pebbly beaches, sloping or flat beaches, and concrete or man-made beaches. Since there are many different kinds of beaches, there is no way to categorize them all.

Why does sand heat up so quickly?

While many people assume sand warms up quickly because it generates heat from its grains, the true reason for its heating properties is because sunshine not only heats 12 inches down in the top of the beach, it also heats all that is underneath. The sands surface temperature may get as high as 160 degrees Fahrenheit.

The reason sand doesn’t cool off at night in contrast to a concrete or asphalt surface is that heat radiates to cooler surfaces and travels upwards less effectively through sand.

During noon hours, hot air above us rises due to thermal convection and this creates an area of lower pressure called a bowl where winds rush in to fill it- perfect conditions for speeding up heat diffusion. Hot air over sunbathers on hot sandy beaches rises which pulls cooler air from the water and up over the beach.

What can you see on a beach?

There is no way to know what one may encounter when taking a walk along this natural phenomenon known as “the shore.”
