I just got back from a vacation from Hawaii. It was really fun! The beaches were beautiful with their white sand. Did you know that there are many colored beaches! Many people believe that sand is made through erosion. In some cases that is true, but in the ocean what is there to erode? Coral? Sure, but that can't account for all the sand made. Ever heard of the black sand beach? That sand was made when lava flowed into the water and literally exploded. These small particles became sand. Some of it eroded slightly. Most of the white sand you see is small shells and bits of dead marine life that has washed up on shore. Sometimes though it is made by fish. Parrot fish can produce hundreds of pounds of sand every year. Everything that goes in has to come out right? That stuff becomes sand. Gross! So these beautiful beaches are actually fish poop!
