The amazing beauty of sand

Sand is a granular material (diameter 0.07 ~ 2 mm), formed from broken lava, washed away by rainwater, eroded, or created by humans crushing rocks.

There are many types of sand, including: river sand, sea sand, yellow sand, natural mineral sand... The main component of river sand is Silicon Dioxide (also known as Silica SiO2).

Dr. Gary Greenberg, put sand grains (Hawaiian sea) into a microscope - magnified 300 times, took pictures that surprised and delighted us.

Don't look at the small grain of sand and underestimate the hidden beauty. Aren't we all just small grains of sand?
