Texas is the 2nd largest state in the United States and the 28th to be admitted to the Union. Texas was admitted to the Union on December 29, 1845. Texas was previously known as the Republic of Texas.

Texas is situated in the n the south-central part of the United States of America. Three of its borders are defined by rivers. The Rio Grande river forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south. The Red River forms a natural border with Oklahoma and Arkansas to the north. The Sabine River forms a natural border with Louisiana to the east. The Texas Panhandle has an eastern border with Oklahoma at 100° W, a northern border with Oklahoma at 36°30' N and a western border with New Mexico at 103° W. El Paso lies on the state's western tip at 32° N and the Rio Grande.

The large size of Texas and its location at the intersection of multiple climate zones gives the state highly variable weather. The Panhandle of the state has colder winters than North Texas, while the Gulf Coast has mild winters. Texas has wide variations in precipitation patterns. El Paso, on the western end of the state, averages as little as 8 inches (200 mm) of annual rainfall while Houston, on the southeast Texas averages as much as 54 inches (1,400 mm) per year. Dallas in the North Central region averages a more moderate 37 inches (940 mm) per year.

Snow falls multiple times each winter in the Panhandle and mountainous areas of West Texas, once or twice a year in North Texas, and once every few years in Central and East Texas. Snow rarely falls south of San Antonio or on the coast except in rare circumstances. Of note is the 2004 Christmas Eve Snowstorm was the first recorded White Christmas in Houston where 6 inches (150 mm) of snow fell as far south as Kingsville, where the average high temperature in December is 65° F.

Maximum temperatures in the summer months average from the 80s °F (26 °C) in the mountains of West Texas and on Galveston Island to around 100 °F (38 °C) in the Rio Grande Valley, but most areas of Texas see consistent summer high temperatures in the 90 °F (32 °C) range.

Thunderstorms strike Texas often, especially the eastern and northern portions of the state. Tornado Alley covers the northern section of Texas. The state experiences the most tornadoes in the United States, an average of 139 a year. These strike most frequently in North Texas and the Panhandle.] Tornadoes in Texas generally occur in the months of April, May, and June.

Texas is home to Big Bend National Park and Guadaloupe Mountains National Park. It is also home to the second largest canyon in the country, Palo Duro Canyon.
