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?
1_Wizard
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.

Certainly, I had not considered that. I would imagine it is quite high on beaches who see very little foot traffic. May explain the different colors of coastal sand as well.

The data regarding beaches also includes certain areas some may not even consider beaches because they are so small while most are larger geological units.

I can see that being the case. Who would consider a small patch of sand at the edge of a forrest a 'beach'? Could lead to some interesting studies though.
