Final answer:
Most rivers in Texas flow through the Eastern Region due to the wetter climate influenced by the Gulf of Mexico, which contrasts with the drier Western Region.
Step-by-step explanation:
The Texas rivers are an integral part of the state's geography, with most flowing through the Eastern Region. This region benefits from the moisture brought by the Gulf of Mexico, giving rise to a wetter climate favorable for river flow. In contrast, the Western Region of Texas, along with New Mexico and Arizona, experiences arid conditions more suited to cattle ranching. As a result of these arid conditions, fewer rivers flow through the Western Region, and those that do often rely on irrigation to support farming operations.
The Dallas-Fort Worth-Arlington metro area in Eastern Texas is part of the Southwest's Sun Belt, driving growth and urbanization. Access to water resources, such as rivers, has undoubtedly contributed to this growth. Rivers provide necessary water supplies for the region's population and industries, despite the varying climatic conditions across the broader Southwest.
