Question

Answer 1

Enumerated powers are spelled out in the Constitution - e.g. to coin money at the federal level and the Senate to approve treaties.

Reserved powers are reserved to the States.  In the early days, most power was still at the State level.  Most criminal law is still at the State level - unless you cross a state line.

Implied powers are hard to define but a good example is the interstate highway system.  No where in the Constitution does it say the federal government can build such an expensive and expansive system of roads.  The Commerce Clause states "The Congress shall have power . . . To regulate commerce with foreign nations, and among the several states, and with the Indian tribes" and from that Congress has the implied power to build highways.
