Texas is the second largest state in the United States by both land area and population. It is located in the south central region of the country with Mexico and the Gulf of Mexico along its southern border. The physical geography of the state encompasses plains, forests, and mountains with climates ranging from wet coastal areas to dry and barren deserts. The state has significant reserves of oil and natural gas, both on dry land and in the Gulf of Mexico. The GDP of Texas is over $1 trillion, a figure larger than that of most developed nations. Texas is the leading U.S. producer of oil and natural gas. Many of the state’s manufacturing companies are located along the Gulf Coast in close proximity to gas and oil resources. Texas leads the country in cattle and cotton production and is home to more farmland, sheep, and lambs than any other state.
