The beach is one of my favorite vacation spots. Its a landform alongside a large body of water.
I could spend a great deal of time at the beach. I like how each separate period of the day creates a whole new experience. 
The sand feels so good under your feet. Beaches can also have gravel, pebblies, or rock.
I like when the weather is mild, but there is a strong breeze. The swaying of the waves is quite serene. 
There are also wild beach that are untouched and underdeveloped.
Probably a haven for a great deal of wildlife. 
I definitely agree. Also, sand is actually made from mollusc shells or coralline algae.
I think that explains why it can wreak havoc with glass, because those can be naturally very sharp.
