Among the following pairs of mineral and district, which one is correc...
Correctly matched pair: Limestone - Kaimur
Explanation:
- Limestone is a sedimentary rock composed mostly of calcium carbonate (CaCO3) in the form of the mineral calcite. It is commonly used as a building material and in the production of cement.
- Kaimur is a district in Bihar, India. It is known for its abundant limestone deposits.
- Therefore, the pair "Limestone - Kaimur" is correctly matched as Kaimur district in Bihar is known for its limestone deposits.
Let's look at the other options and why they are incorrect:
Mica - Bhagalpur:
- Mica is a group of minerals that are highly valued for their electrical and heat insulation properties. It is used in various industries, including electronics, cosmetics, and construction.
- Bhagalpur is a city in Bihar, India. It is not known for its mica deposits.
- Therefore, the pair "Mica - Bhagalpur" is incorrectly matched.
Quartzite - Madhubani:
- Quartzite is a metamorphic rock that is formed from sandstone. It is composed primarily of quartz, and it is known for its hardness and durability.
- Madhubani is a district in Bihar, India. It is not known for its quartzite deposits.
- Therefore, the pair "Quartzite - Madhubani" is incorrectly matched.
Lead-zinc - Gaya:
- Lead and zinc are metallic elements that often occur together in nature. They are commonly used in various industries, including construction, batteries, and alloys.
- Gaya is a district in Bihar, India. While there are some occurrences of lead and zinc in Bihar, Gaya is not specifically known for its lead-zinc deposits.
- Therefore, the pair "Lead-zinc - Gaya" is incorrectly matched.
In conclusion, among the given options, the only correctly matched pair of mineral and district is "Limestone - Kaimur".
