how many states share a border with oklahoma
Oklahoma Oklahoma is the 20th-largest state in the United States, covering an area of 69,898 square miles (181,035 km2), with 68,667 square miles (177,847 km2) of land and 1,281 square miles (3,188 km2) of water.[20] It lies partly in the Great Plains near the geographical center of the 48 contiguous states. It is bounded on the east by Arkansas and Missouri, on the north by Kansas, on the northwest by Colorado, on the far west by New Mexico, and on the south and near-west by Texas. Much of its border with Texas lies along the Southern Oklahoma Aulacogen, a failed continental rift. The geologic figure defines the placement of the Red River.
Territorial evolution of the United States Regarding internal borders, while territories could shift wildly in size, once established a state has commonly remained within its borders, barring small changes due to river shifts. Only four states – Maine, Kentucky, Vermont, and West Virginia – have been created from land claimed by another state; all of the others were created from territories or directly from acquisitions. The last state of the contiguous United States, commonly called the "lower 48," was admitted in 1912; the fiftieth and most recent state was admitted in 1959.
