Consider the following statements regarding the elevation of plains: 1. They are generally not more than 200 metres above mean sea level. 2. All plains are extremely level without any rolling features. 3. Plains are generally formed at low elevations relative to sea level. Which of the statements given above is/are correct?

The correct option is (c) 1 and 3 only. Explanation Plains are extensive stretches of flat or gently rolling land. They are one of the major landforms on Earth, alongside mountains and plateaus. While they are often associated with lowlands, their formation can be attributed to various geomorphic processes, including deposition by rivers, wind, and glaciers, or erosion of elevated lands. Statement-wise Analysis: - Statement 1 is Correct: Generally, plains are defined as low-lying flat lands with an elevation of not more than 200 metres above mean sea level. However, this is a general classification, and exceptions exist (e.g., interior plains or high plains). - Statement 2 is Incorrect: It is factually incorrect to state that all plains are extremely level. While some plains are extremely flat (level), many others possess a rolling or undulating topography. For instance, glacial plains often exhibit uneven surfaces due to depositional features like drumlins or moraines. - Statement 3 is Correct: Plains are generally characterized by their low elevation relative to sea level and surrounding areas. Most of the world's major plains are formed by rivers and their tributaries in low-lying basins. Key Takeaway: Plains are generally low-lying landforms (usually <200m above MSL) but are not always perfectly level; they can be rolling or undulating depending on their geomorphic origin (erosional or depositional).

Solution

The correct option is (c) 1 and 3 only.

Explanation

Plains are extensive stretches of flat or gently rolling land. They are one of the major landforms on Earth, alongside mountains and plateaus. While they are often associated with lowlands, their formation can be attributed to various geomorphic processes, including deposition by rivers, wind, and glaciers, or erosion of elevated lands.

Statement-wise Analysis:

Statement 1 is Correct: Generally, plains are defined as low-lying flat lands with an elevation of not more than 200 metres above mean sea level. However, this is a general classification, and exceptions exist (e.g., interior plains or high plains).
Statement 2 is Incorrect: It is factually incorrect to state that all plains are extremely level. While some plains are extremely flat (level), many others possess a rolling or undulating topography. For instance, glacial plains often exhibit uneven surfaces due to depositional features like drumlins or moraines.
Statement 3 is Correct: Plains are generally characterized by their low elevation relative to sea level and surrounding areas. Most of the world's major plains are formed by rivers and their tributaries in low-lying basins.

Key Takeaway:

Plains are generally low-lying landforms (usually <200m above MSL) but are not always perfectly level; they can be rolling or undulating depending on their geomorphic origin (erosional or depositional).
