Consider the following statements regarding the Aravali range: 1. It is one of the oldest fold mountain systems in the world. 2. It has grown significantly in height due to recent deposition. 3. It has worn down due to the process of erosion. Which of the statements given above is/are correct?

Correct Option The correct option is (c) 1 and 3 only. Explanation The Aravali range is a classic example of Old Fold Mountains. Unlike Young Fold Mountains (e.g., the Himalayas), which are tectonically active and rising, Old Fold Mountains have undergone extensive denudation over geological time scales, resulting in Relict or Residual Mountains. Statement-wise Analysis - Statement 1 is Correct: The Aravali range is one of the oldest fold mountain systems in the world. Its geological origin dates back to the Proterozoic era (Pre-Cambrian period), making it significantly older than the Himalayas. - Statement 2 is Incorrect: The Aravali range has not grown in height due to recent deposition. Deposition is a process that typically fills low-lying areas (aggradation). Mountains grow primarily through tectonic uplift (endogenic forces). Conversely, the Aravalis have been subjected to degradation for millions of years, reducing their height. - Statement 3 is Correct: Over millions of years, the Aravali range has been worn down by exogenic forces such as weathering and erosion. Consequently, they now exist as eroded stubs or "relict" mountains, significantly lower in elevation than their original structure. Key Takeaway Relict Mountains (or Mountains of Accumulation/Denudation) represent the remnants of ancient mountain systems that have been lowered and sculpted by prolonged erosion.

Solution

Correct Option

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

Explanation

The Aravali range is a classic example of Old Fold Mountains. Unlike Young Fold Mountains (e.g., the Himalayas), which are tectonically active and rising, Old Fold Mountains have undergone extensive denudation over geological time scales, resulting in Relict or Residual Mountains.

Statement-wise Analysis

Statement 1 is Correct: The Aravali range is one of the oldest fold mountain systems in the world. Its geological origin dates back to the Proterozoic era (Pre-Cambrian period), making it significantly older than the Himalayas.
Statement 2 is Incorrect: The Aravali range has not grown in height due to recent deposition. Deposition is a process that typically fills low-lying areas (aggradation). Mountains grow primarily through tectonic uplift (endogenic forces). Conversely, the Aravalis have been subjected to degradation for millions of years, reducing their height.
Statement 3 is Correct: Over millions of years, the Aravali range has been worn down by exogenic forces such as weathering and erosion. Consequently, they now exist as eroded stubs or "relict" mountains, significantly lower in elevation than their original structure.

Key Takeaway

Relict Mountains (or Mountains of Accumulation/Denudation) represent the remnants of ancient mountain systems that have been lowered and sculpted by prolonged erosion.

Consider the following statements regarding the geomorphic processes acting on the Earth: 1. The internal process leads to the continuous wearing down and rebuilding of the land surface. 2. The internal process results in the upliftment and sinking of the earth’s surface. 3. The wearing away of the earth’s surface is termed as erosion, while rebuilding happens through deposition.
