California's diverse geography ranges from the Pacific Coast in the west to the Sierra Nevada mountain range in the east; and from the redwood–Douglas fir forests in the northwest to the Mojave Desert in the southeast. The Central Valley, a major agricultural area, dominates the state's center. Though California is well-known for its warm Mediterranean climate, the large size of the state results in climates that vary from moist temperate rainforest in the north, to arid desert in the interior, as well as snowy alpine in the mountains.
Houston is the most populous city in Texas and the fourth largest in the U.S., while San Antonio is the second most populous in the state and seventh largest in the U.S. Dallas–Fort Worth and Greater Houston are the fourth and fifth largest metropolitan statistical areas in the country, respectively. Other major cities include Austin, the second most populous state capital in the U.S., and El Paso. Texas is nicknamed "The Lone Star State" to signify its former status as an independent republic, and as a reminder of the state's struggle for independence from Mexico. The "Lone Star" can be found on the Texas state flag and on the Texan state seal. The origin of Texas's name is from the word "Tejas," which means "friends" in the Caddo language.
