Match List-I with List-II and select the correct answer using the code given below the Lists : List-I (Weathering type) A. Chemical weathering B. Mechanical weathering C. Glacial deposits D. Deposition by ground- List-II (Landform/ Process) 1. Till 2. Oxidation 3. Plant roots 4. Stalactite Code :

The matching of weather types and landforms is as follows: Chemical weathering includes oxidation, a process where minerals react with oxygen, often leading to rock weakening and color changes. Mechanical weathering involves physical disintegration; plant roots contribute to this by exerting pressure in rock crevices, a process known as root pry [2]. Glacial deposits are characterized by till, which is unassorted coarse and fine debris dropped by melting glaciers [3]. Deposition by groundwater leads to the formation of stalactites, which are icicle-shaped mineral deposits hanging from the ceilings of caves. While biological weathering can be both mechanical and chemical, plant roots are a primary example of biological-mechanical action [2]. Therefore, the correct sequence for A-B-C-D is 2-3-1-4, matching Option 1.
