Consider the following statements:(i) Block Mountains are created when...
The correct option is Option C.
Block Mountains: When large areas are broken and displaced vertically, Block Mountains are formed. In this case, the uplifted blocks are called horsts. On the other hand, the lowered blocks are called graben.
The Vosges Mountains in France and Black Forest in Germany are examples of horsts, as are the Table, Jura, the Dole mountains and the Rila - Rhodope Massif including the well defined horsts of Belasitsa (linear horst), Rila mountain (vaulted domed shaped horst) and Pirin mountain - a horst forming a massive anticline.

Block Mountains and Horst
Block Mountains and Horst are geological features that are formed due to different processes. Let's analyze each statement to determine their correctness.
Statement (i): Block Mountains are created when large areas are broken and displaced vertically.
- Block Mountains are formed when large areas of the Earth's crust are uplifted and tilted, resulting in the formation of steep mountain ranges.
- The uplift and tilting occur due to tectonic forces such as faulting and folding.
- Examples of Block Mountains include the Sierra Nevada in the United States and the Harz Mountains in Germany.
Statement (ii): The Vosges Mountain in Europe is an example of Horst
- A Horst is a raised block of the Earth's crust bounded by normal faults.
- The Vosges Mountains in Europe are indeed an example of a Horst, as they are a series of parallel mountain ranges separated by down-dropped fault blocks.
Conclusion
- Both statements are correct. Block Mountains are indeed created when large areas are broken and displaced vertically, and the Vosges Mountains in Europe represent an example of a Horst.
