Sill is a type of Volcanic Landform. The lava that is released during volcanic eruptions on cooling develops into igneous rocks. The cooling may take place either on reaching the surface or also while the lava is still in the crustal portion. Depending on the location of the cooling of the lava, igneous rocks are classified as volcanic rocks (cooling at the surface) and plutonic rocks (cooling in the crust).
The lava that cools within the crustal portions assumes different forms. These forms are called intrusive forms. The near horizontal bodies of the intrusive igneous rocks are called sill or sheet, depending on the thickness of the material. The thinner ones are called sheets, while the thick horizontal deposits are called sills. Arete is a type of Glacial landform. Horns form through headward erosion of the cirque walls. If three or more radiating glaciers cut headward until their cirques meet, high, sharp, pointed and steep-sided peaks called horns form.
The divides between cirque side walls or head walls get narrow because of progressive erosion and turn into serrated or saw-toothed ridges, sometimes referred to as Aretes, with very sharp crests and a zig-zag outline. An inselberg is an isolated hill, ridge, or small mountain that abruptly protrudes out from a virtually level surrounding plain. The word inselberg translates to "Island Mountain" in German. A massive inselberg is referred to as a Bernhardt, which manifests as dome-topped, bare, and steep-sided. A Bernhardt mostly occurs in arid and semi-arid regions. Stalactiteis a depositional landform.
The most common stalactites are speleothems, which occur in limestone caves. Stalactites hang as icicles of different diameters. Normally they are broad at their bases and taper towards the free ends showing up in a variety of forms. Stalagmites rise up from the floor of the caves. In fact, stalagmites form due to dripping water from the surface or through the thin pipe, of the stalactite, immediately below it. So, Option (b) is correct.

Match the following pairs : Landform Agent/Region1. Sill - Desert (A)2...
Explanation:
1. Sill - Desert (A)
- A sill is a tabular sheet of igneous rock that has been intruded between older layers of sedimentary rock.
- Deserts are regions characterized by low precipitation and often have flat, exposed landforms.
- Therefore, the correct match for sill would be Desert.
2. Arete - Limestone (B)
- An arete is a narrow ridge of rock that separates two valleys.
- Limestone is a type of sedimentary rock that is often associated with karst landscapes.
- The match between arete and limestone is a common occurrence in mountainous regions.
3. Inselberg - Volcano (C)
- An inselberg is an isolated hill or mountain that rises abruptly from a plain or relatively flat terrain.
- Volcanoes are landforms created by the eruption of magma from beneath the Earth's crust.
- The match between inselberg and volcano does not accurately represent the formation processes of these landforms.
4. Stalactite - Glacier (D)
- A stalactite is a type of mineral formation that hangs from the ceiling of caves, often formed by the dripping of mineral-rich water.
- Glaciers are large bodies of ice that move slowly over land surfaces.
- The match between stalactite and glacier does not accurately represent the formation processes of these landforms.
Therefore, the correct match among the given pairs is:
1-C, 2-D, 3-A, 4-B (Option B)
1. Sill - Desert (A)
- A sill is a tabular sheet of igneous rock that has been intruded between older layers of sedimentary rock.

- Limestone is a type of sedimentary rock that is often associated with karst landscapes.
- The match between arete and limestone is a common occurrence in mountainous regions.
3. Inselberg - Volcano (C)
- An inselberg is an isolated hill or mountain that rises abruptly from a plain or relatively flat terrain.
- Volcanoes are landforms created by the eruption of magma from beneath the Earth's crust.
- The match between inselberg and volcano does not accurately represent the formation processes of these landforms.
4. Stalactite - Glacier (D)
- A stalactite is a type of mineral formation that hangs from the ceiling of caves, often formed by the dripping of mineral-rich water.
- Glaciers are large bodies of ice that move slowly over land surfaces.
- The match between stalactite and glacier does not accurately represent the formation processes of these landforms.
Therefore, the correct match among the given pairs is:
1-C, 2-D, 3-A, 4-B (Option B)
