Q. Which of the following statements with regard to the Appalachian Plateau is/are correct?
1.It is a highly rugged, deeply dissected plateau that marks the northwestern face of the larger Appalachian mountain system.
2.Unlike a typical flat tableland, its modern mountainous appearance is the result of long-term fluvial erosion cutting deep V-shaped valleys into an uplifted plain.
3.Geographically, it forms an elongated block that stretches from the state of New York down to southern Florida.
Select the correct answer using the code given below:
Answer: A
Notes:
Detailed Explanation:
- Statement 1 is correct: The Appalachian Plateau is the westernmost physiographic province of the Appalachian Mountains, extending from New York southwestward through Pennsylvania, West Virginia, Ohio, Kentucky, and Tennessee, down to Alabama.
- Statement 2 is correct: Though it looks like a mountain range to an observer on the ground, it is geologically a dissected plateau. It consists of a flat, elevated block of sedimentary rock that has been heavily carved into sharp hills and valleys by rivers over millions of years.
- Statement 3 is incorrect: The plateau terminates in northern Alabama, not Florida. Florida is entirely made up of low-lying coastal plains and karstic limestone structures, completely outside the Appalachian system.
