Detailed Explanation of Matches
Granite: Bridges
Granite is a hard, granular, igneous rock composed primarily of quartz, feldspar, and mica. Its exceptional strength, durability, and resistance to weathering make it an ideal material for heavy-duty applications. Consequently, granite is frequently used in constructing bridges, particularly for foundations, pillars, and decking, where structural integrity is paramount.
Limestone: Production of Cement
Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). Its primary industrial use is in the production of cement. When limestone is heated to high temperatures, it undergoes a chemical process to create lime, a fundamental component of cement. It's also used as a building material and aggregate.
Marble: Ornamental Work
Marble is a metamorphic rock formed from recrystallized carbonate minerals, most commonly calcite. It is celebrated for its beauty, often displaying intricate patterns and colours. Because of its aesthetic qualities, marble is widely employed in ornamental work, including sculptures, decorative elements in buildings, countertops, and luxurious flooring.
Slate: Flooring
Slate is a fine-grained metamorphic rock formed from shale or mudstone. It possesses the unique characteristic of being able to split easily into thin, durable sheets. This property makes slate a popular choice for roofing, but it is also highly valued for creating attractive and long-lasting flooring options in both residential and commercial spaces.
Summary of Stone Matches
| Stone (List 1) | Use (List 2) | Correct Match |
|---|---|---|
| A. Granite | Bridges | A-ii |
| B. Limestone | Production of cement | B-iii |
| C. Marble | Ornamental work | C-i |
| D. Slate | Flooring | D-iv |
The correct pairings derived from the properties and uses of these stones are: Granite for Bridges, Limestone for Cement Production, Marble for Ornamental Work, and Slate for Flooring.
Therefore, the correct option representing these matches is A-ii, B-iii, C-i, D-iv.
