Answer 1

The powers of the congress are given in the constitution.Congress is given the power to regulate commerce or trade with foreign nations and among the several states and with the Indian tribes. This is the commerce clause.The components of the commerce clause are the foreign commerce clause, the interstate commerce clause and the Indian commerce clause.The commerce clause has become restricted to matters of trade.Thus the  commerce clause shows  the 3 most important powers delegated to the congress by the constitution.

The commerce clause gives power to the US over navigable waters.So navigable waters are the public property of the nation.The power to control navigation is a big power granted to US.So federal rights in navigable waters is the significance of the commerce clause.So the constitution gives power to congress the power to regulate trade.
