How they are connected: The Connected States of America graphic shows three layers: The United States of America experience an increase in urbanization which is shown in the lowest layer representing the population density per square mile. The center layer shows the mobile connections between the people, where a link represents reciprocal phone calls and the color assigns the respective community which in turn are shown in the communities layer. The height of the link represents call volume between any two counties.
How they are not connected: The contiguous United States (also known as the United States Mainland) does not include Alaska, Hawaii, or any other territories under the control of the United States. ... However, Alaska is not part of the "Contiguous United States", because it is not attached directly to the lower 48 states.
(I am not that sure tbh :/ )
Hope you the best with your studying
