What is the fundamental reason underlying the difference between both civil and criminal cases that can be filed in federal court and those that can be filed in state courts?

state courts deal with only original trials and federal courts deal with only appellate issues.

federal courts deal with issues granted to them by the u. s. constitution and state courts deal with issues granted to them by the constitution.

federal courts are the courts of last resort and state courts are trial courts with limited jurisdiction.

state courts deal with issues of state law and federal courts deal with issues granted to them by the u. s. constitution.

The answer is " State courts deal with issues of state law and federal courts deal with issues granted to them by the U.S. Constitution."

Explanation:

In the USA state courts have jurisdiction over disputes that have a connection with a state´s laws. They usually deal with common laws. They apply laws existing or approved in a state or that are according to the state´s constitution.  The federal courts can only take cases defined in the Constitution of the USA or by federal statutes. The definite level a case may reach is the Supreme Court which is a federal court.
