A partly enclosed coastal body of water in which river water is mixed with seawater is called an estuary. An estuary is thus defined by salinity rather than geography. Many coastal features designated by other names are in fact estuaries (for instance, Chesapeake Bay). Some of the oldest continuous civilizations have flourished in estuarine environments (for example, the Tigris and Euphrates rivers, the Nile delta, and the Ganges delta).
âFederal crimesâ refer specifically to offenses that violate U.S. federal laws. They are investigated by federal law enforcement and prosecuted by United States attorneys in federal courts with federal judges.
Difference between charged with a State and a Federal crime. The differences between federal and state crimes can be complicated. Many different laws overlap in the criminal arena, and doubts and questions are created as to what criminal court should prosecute the crime. If the crime happens in one state, it is typically a state crime, unless it is an expressly named federal crime.
