Which statement best describes the sequential development of mesas and buttes?
Answer and explanation
Correct answer: A broad flat-topped mesa may become a smaller isolated butte after further erosion
The correct answer is A. In a dry region of horizontally layered rocks, a resistant cap rock protects the softer beds beneath it. The remaining broad, flat-topped plateau is a mesa. As erosion narrows and isolates the protected remnant, it may become a smaller butte. A butte is therefore not a marine spit, a glacial valley, or a karst cave deposit, making B, C, and D incorrect.
