what is the constituion of the united states
United States Constitution The United States Constitution is the supreme law of the United States.[1] The Constitution, originally comprising seven articles, delineates the national frame of government. Its first three articles entrench the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral Congress; the executive, consisting of the President; and the judicial, consisting of the Supreme Court and other federal courts. Articles Four, Five and Six entrench concepts of federalism, describing the rights and responsibilities of state governments and of the states in relationship to the federal government. Article Seven establishes the procedure subsequently used by the thirteen States to ratify it.
United States The United States of America (USA), commonly known as the United States (U.S.) or America (/əˈmɛrɪkə/), is a federal republic[14][15] composed of 50 states, a federal district, five major self-governing territories, and various possessions.[fn 6] At 3.8 million square miles (9.8 million km2)[17] and with over 324 million people, the United States is the world's third- or fourth-largest country by total area[fn 7] and the third-most populous. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The state of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.[22]
