I love going to beaches that consist of loose particles.
Loose particles? Do you mean sand?
Yep, sand is typically made from rock, such as sand, gravel, shingle, pebbles
Interesting. It must take a long time for rocks to turn into such small pieces.
Yes centuries actually. Thats why beaches are known for untouched beauty and preserved nature.
They are definitely beautiful. It's sad that so many are poorly maintained and end up with litter everywhere.
I agree,  man-made infrastructure, such as lifeguard posts, have ruined the natural look of beaches.
That's true. However, I think preventing drowning is more important than maintaining the natural look.
