Which description matches the Central Plains of Texas?

• A. High and Flat, with minerals like limestone and granite.
• B. Very mountainous with high elevations.
• C. Coastal marshes with mangroves.
• D. Desert with sand dunes.

Answer: (A)

The Central Plains in Texas are an inland, broad expanse of flat to gently rolling prairie at a higher elevation than the coast, where sedimentary rocks like limestone are common and granite appears in some uplifted areas. That combination—high, flat land with limestone in the bedrock and some granite outcrops—best describes the Central Plains. The other descriptions point to regions that don’t match: mountainous terrain isn’t part of the Central Plains, coastal marshes with mangroves belong to the Gulf Coastal Plain, and a desert with sand dunes describes far western Texas.
