What distinguishes old fold mountains like the Aravallis from new fold mountains such as the Andes and the Rockies?
  • a)
    Old fold mountains have higher elevations and pointed peaks, while new fold mountains have rounded peaks and gradual slopes.
  • b)
    Old fold mountains are formed by volcanic activity, while new fold mountains result from erosion and weathering processes.
  • c)
    Old fold mountains are characterized by deep valleys, while new fold mountains have shallow depressions.
  • d)
    Old fold mountains are shorter and have rounded peaks, while new fold mountains are continuously rising due to plate movements.
Correct answer is option 'D'. Can you explain this answer?

Old fold mountains like the Aravallis are characterized by rounded peaks, gradual slopes, and shorter heights, having been formed millions of years ago through horizontal plate movements. On the other hand, new fold mountains such as the Andes and the Rockies are continuously rising due to ongoing horizontal plate movements, resulting in higher elevations, pointed peaks, and deep valleys.

Distinction Between Old and New Fold Mountains
Old fold mountains and new fold mountains exhibit distinct characteristics primarily due to their geological formation processes and age.
Characteristics of Old Fold Mountains
- Old fold mountains, such as the Aravallis, are typically formed millions of years ago.
- They have undergone extensive erosion, resulting in shorter heights.
- Their peaks are often rounded due to the weathering processes over time.
- Examples include the Aravalli Range in India and the Appalachian Mountains in North America.
Characteristics of New Fold Mountains
- New fold mountains, like the Andes and Rockies, are relatively young in geological terms.
- They are still actively rising due to tectonic plate movements.
- These mountains feature pointed peaks and steep slopes, as they have not yet been significantly eroded.
- Their formation is often associated with volcanic activity and the convergence of tectonic plates.
Continued Geological Activity
- New fold mountains are characterized by ongoing geological activity, including earthquakes and volcanic eruptions.
- The continuous rise of these mountains contributes to their rugged terrain and jagged features.
Conclusion
In summary, the primary distinction lies in the age and condition of these mountains. Old fold mountains are shorter with rounded peaks due to erosion, while new fold mountains are taller, with pointed peaks and are still rising. This difference reflects the dynamic nature of Earth’s geology.
