Texas lies in the south-central part of the
United States of America. Texas is considered to form part of the US South and also part of the U.S. Southwest. Some regions of Texas are associated with the South more than the Southwest, (primarily East Texas), while other regions share more similarities with the Southwest than the south (primarily West Texas and South Texas).
Texas has four major physical regions:
1) The
Gulf Coastal Plains, from the Gulf of Mexico inland to the Balcones Fault and the Eastern Cross Timbers;
2) The Interior Lowlands are bounded by the Caprock Escarpment to the west, the
Edwards Plateau to the South, and the Eastern Cross Timbers to the east;
3) The
Great Plains that include the Llano Estacado, the Panhandle, Edwards Plateau, Toyah Basin, and Llano Basin;
4) The Basin and Range Province, in extreme western Texas, west of the
Pecos River beginning with the
Davis Mountains on the east and the Rio Grande to its west and south. This is the only part of Texas regarded as mountainous and includes seven named peaks in elevation greater than 2438 m.
