Pea gravel is mined from river and stream beds.  Crushed-stone gravel comes from quarries.  The latter type is commonly used in concrete (pea gravel is sometimes used in a surface layer).  I am not an engineer, but I do live near a gravel pit.

Gravel/sand/clay come from river beds, generally. Quarries are when
you blast half a hill away.

But I'm not an engineer...
