The Sambhar Salt Lake, India's largest inland Salt Lake, is located 96 km southwest of the city of Jaipur, Rajasthan. One-tenth of total salt production in India comes from Sambhar lake.

D is the correct option.Gold, silver, platinum, and palladium each have an ISO 4217 currency code. The best known “precious metals” are the coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art, jewelry, and coinage.

B is the correct option.In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints. The smaller occurrences are called Veins and the larger is called Lodes. In most cases, they are formed when minerals in liquid/molten and gaseous forms are forced upward through cavities towards the earth's surface.

The water covered surface of the Earth is three-fourth.
Explanation:
- The Earth is primarily composed of water and land.
- The water covered surface of the Earth refers to the area that is covered by water bodies such as oceans, seas, lakes, and rivers.
- To determine the percentage of the water covered surface, we need to compare it to the total surface area of the Earth.
- The Earth has a total surface area of approximately 510 million square kilometers.
- The total area covered by water bodies is estimated to be about 361 million square kilometers.
- To find the percentage, we divide the area covered by water by the total surface area of the Earth and multiply by 100.
- (361 million sq km / 510 million sq km) x 100 = 70.78%
- Therefore, the water covered surface of the Earth is approximately three-fourth or 70.78% of the total surface area.
- This means that only about one-fourth or 29.22% of the Earth's surface is covered by land.
- So the correct answer is B: three-fourth.

In the pre-independence period, most manufacturing units were located in places suitable for overseas trade like Mumbai, Kolkata, Chennai, etc. The reason was to reduce the cost of ​manufacturing (due to low transportation costs to bring-in raw materials) and transportation from manufacturing units to seaport.

Correct Answer :- a

Explanation : Many industries tend to come together to make use of the

advantages offered by the urban centres. Industrialisation and urbanisation go hand in hand. Cities provide markets and also provide services such as banking, insurance, transport, labour, consultants and financial advice, etc. to the industry.

About 97.3% of Earth's total volume of water is found in the ocean. As per the given Options, Option (1) is the most appropriate answer.

Important Points

• The Earth's surface is covered with 71 percent of water due to which it is also known as the blue planet.
• Around 97% of the earth's water is found in the oceans
• But it is too salty for drinking, growing crops, and most industrial uses except cooling
• The water in the ocean contains dissolved salt which is unfit for drinking.
• Most of the salt found in the ocean is sodium chloride.
• The average salinity of the oceans is 35 parts per thousand.

Suppliers of Tools, Implements, Fertilisers, Tractors, etc.

• Industry: The majority of tools, implements, fertilisers, tractors, etc. are supplied by the industry. This includes manufacturers and suppliers who produce and distribute agricultural equipment and inputs.



• Government: In some cases, the government may also provide subsidies or support for the procurement of tools, implements, fertilisers, tractors, etc. to farmers. However, the primary suppliers are usually from the industry.



• People: Farmers themselves may also purchase these items directly from stores or suppliers. While they may not be the primary source of production, individual farmers play a significant role in the supply chain by purchasing and using these tools and inputs on their farms.



• None of these: While the government and individual farmers may play a role in the supply of agricultural tools and inputs, the industry remains the primary source of these items.

By understanding the different suppliers of tools, implements, fertilisers, tractors, etc., farmers can make informed decisions on where to source the necessary equipment for their agricultural activities.

Answer:
The National Highway No.1 is known by the following name:
- Sher Shah Suri Marg
Explanation:
The National Highway No.1 in India is also known as Sher Shah Suri Marg. It is a major north-south highway that stretches from Delhi to Attari in Punjab. This highway is named after Sher Shah Suri, who was the founder of the Sur Empire in North India during the 16th century. Sher Shah Suri Marg is an important road link that connects the capital city of Delhi with various towns and cities in Punjab, including Amritsar. It is a well-maintained and busy highway that facilitates the movement of goods and passengers between Delhi and Punjab.

Deserts soils are usually light coloured with minimal humus content due to which the plant productivity is low. Also, the water-retaining capacity is very less. However, they are rich in minerals- calcium carbonate (caliche), gypsum, and/or salts.

The alluvial soil consists of various proportions of sand, silt and clay. Alluvial soils as a whole are very fertile. Mostly these soils contain an adequate proportion of potash, phosphoric acid and lime.

The correct answer is Option B: 71%. While the vast majority of Earth's surface is covered by water, approximately 71%, only a small fraction of this is freshwater that can be used by humans. This freshwater is crucial for various purposes, including drinking, agriculture, and industrial activities.

Shillong gets very much rain. So, the common practice is rain harvesting in that place.

The correct answer is Option B: 22%. Hydroelectric power contributes about 22% of the total electricity produced in India. This form of energy plays a significant role in meeting the demands of various industries and sectors.

The correct option is Option D.
When iron ore is converted into iron, manganese removes oxygen and sulfur. Also, it is an essential alloy that helps to convert iron into steel. Hence, manganese is an important raw material for the iron and steel industry.
 

Non-ferrous Minerals:
(i) India’s reserves and production of non- ferrous minerals is not very satisfactory. 
(ii) However, these minerals, which include copper, bauxite, lead, zinc and gold play a vital role in a number of metallurgical, engineering and electrical industries.

India is the largest producer as well as consumer of pulses in world. Since pulses are the major source of protein in a vegetarian diet, these are used by most of the Indian population. They need less moisture and survive even in dry conditions.

The major Rabi crop in India is wheat, followed by barley, mustard, sesame, Oats, Grams, Linseed and peas. Hence, D is the correct option.

Explanation:

• Heavy Industries: Industries which require large amounts of raw materials for their production processes are known as heavy industries.


• Examples: Steel, cement, mining, and chemical industries are considered heavy industries because they require significant quantities of raw materials like iron ore, coal, limestone, etc.


• Characteristics: Heavy industries typically involve large-scale production and capital-intensive processes due to the nature of their raw material requirements.


• Light Industries: In contrast, light industries involve the production of consumer goods or small-scale manufacturing that does not require heavy raw material inputs.


• Market: The term "market" does not directly relate to the classification of industries based on raw material usage.


• Answer: The correct choice is option D: none of these, as heavy industries are not referred to as "market" or "light industries."

Explanation:

• Statement A: Oxalic acid (H₂C₂O₄) can be estimated by titrating against either KOH or KMnO₄ solution.


• Statement B: This statement is not mentioned in the correct options, so it is not true.


• Statement C: K₂C₂O_{4> can be estimated by titrating against either HCl or KClO3 and in both analyses equivalent weight of K2C2O4 is 83. (MW of K2C2O4 = 166)}
