Q. Consider the following statements:

1. Block mountains are formed by the lifting up of land between faults or by the sinking of land outside the faults.
2. A mountain range is produced at the plate boundaries due to Continental-continental collision.

Which of the above statements is / are correct?
Answer: Both 1 and 2 are correct
Notes: Block mountains arise when faulting uplifts or drops sections of the Earth's crust, as seen in horsts and grabens. Additionally, when two continental plates collide at a plate boundary, intense pressure results in orogeny, forming mountain systems like the Himalayas. Therefore, both statements accurately describe processes of mountain formation.
