Final answer:
The majority of water used in Texas comes from multiple sources, such as surface water and groundwater.
Step-by-step explanation:
The majority of water used in Texas comes from multiple sources. One significant source is surface water, such as lakes, rivers, and reservoirs. This water is obtained from the state's extensive network of rivers and reservoirs, including the Rio Grande, the Colorado River, and Lake Texoma. Another important source is groundwater, which is extracted from underground aquifers. Texas has several major aquifers, including the Edwards Aquifer, the Carrizo-Wilcox Aquifer, and the Ogallala Aquifer.
