Q. Consider the following statements:
- Block mountains are formed by the lifting up of land between faults or by the sinking of land outside the faults.
- A mountain range is produced at the plate boundaries due to Continental-continental collision
Which among the above statements is / are correct?
Answer:
Both 1 & 2 are correct
Notes: Block mountains are a type of mountain range characterized by large blocks of uplifted rock separated by faults or grabens. They form when the Earth's crust is stretched and cracked, causing blocks of rock to rise and drop along fault lines. This creates a series of raised plateaus and deep valleys, giving the mountain range a distinctive block-like appearance. Examples of block mountains include the Basin and Range Province in the Western United States and the Horst and Graben structures in the European Alps.
A mountain range can be produced at the plate boundaries due to continental-continental collision. When two continents collide, the resulting pressure can cause the Earth's crust to buckle and form high peaks and ranges. This process is known as orogeny, and can result in the formation of large and complex mountain systems, such as the Himalayas and the Alps.
