What does it mean when a state is not touching any other state of the US?

When a state is not touching any other state in the U.S., it is referred to as being "non-contiguous." This typically applies to states like Alaska and Hawaii, which are separated from the mainland United States. Non-contiguous states may have unique geographic, cultural, and logistical characteristics that distinguish them from contiguous states. Their isolation can impact travel, commerce, and governance.
