Which state is not part of the contiguous United States?

Alaska is not part of the contiguous United States because it is separated from the other 48 states by Canada. The contiguous United States consists of the states that are located on the North American continent and share borders with one another, which means they are all connected. Alaska, however, is located to the northwest of Canada and is not physically connected to any of the other states.

Understanding this distinction is important in geography and citizenship discussions since it highlights the vastness of the U.S. and its territories, as well as the unique geographical characteristics of Alaska compared to the mainland states.
