I grew up right near the beach and I loved it. Do you enjoy the beach?

I love the beach.  Such a beautiful landform that resides alongside bodies of water all over the world.

It really is! We are very lucky in Florida to have so much coastline. I wish all states could enjoy it as well.

Thinking about how the particles of sand can be biological in origin like algae and Mollusc shells goes to show you how so many things are living.

Indeed. I have seen microscopic images of beach sand and they are quite interesting. I wonder what the ratio of biological matter is the whole makeup of beach sand?

That's a good question and I am sure that answer varies based on location.  Some beaches are wild and untouched so the ratio may be quite high.
