Explanation
The classification of landforms based on their formation processes, specifically distinguishing between tectonic features (Block Mountains) and exogenic agents (Glaciers).
- A. Horsts (Matches 2): These are associated with Block Mountains formed by faulting. When the earth's crust fractures, the block of land that is uplifted or remains stationary relative to subsided blocks is called a Horst.
- B. Graben (Matches 1): This refers to the lowered or subsided block of land located between two parallel faults. A Graben typically forms a rift valley or a trench.
- C. Glaciers (Matches 3): Glaciers are massive bodies of dense ice that move under their own weight. They are geographically defined as permanently frozen rivers of ice found in high altitudes or latitudes.
- D. Range (Matches 4): A mountain range is a geographic feature consisting of a series of mountains or hills arranged in a continuous line or chain.
Key Takeaway: In the context of faulting, Horsts represent the uplifted blocks (ridges), while Grabens represent the subsided blocks (valleys). Glaciers act as geomorphic agents of erosion and deposition.
