Detailed Solution: Question 1

The Textile Industry is an Example of Agro-based Industry:
Agro-based industries are those industries that use agricultural products as raw materials for manufacturing various products. The textile industry specifically fits into this category because it heavily relies on natural fibers produced by crops such as cotton, jute, silk, and wool. Here is a detailed explanation of why the textile industry is considered an agro-based industry:
1. Definition of Agro-based Industry:
- Agro-based industries are those industries that process raw materials derived from agriculture to produce finished goods.
- These industries add value to the primary agricultural products and contribute to the overall economy.
2. Raw Materials Used in the Textile Industry:
- The textile industry primarily uses natural fibers such as cotton, jute, silk, and wool.
- Cotton is one of the most widely used fibers in textile manufacturing, and it is obtained from the cotton plant.
- Jute is another important fiber used in the production of sacks, bags, and other packaging materials.
- Silk is derived from the silkworm cocoon and is known for its luxurious feel and appearance.
- Wool is obtained from sheep and is commonly used in the production of warm clothing and textiles.
3. Processing of Raw Materials:
- After the raw materials are harvested or obtained, they undergo several processes to transform them into usable fibers.
- The cotton fibers are separated from the cotton seeds through a process called ginning.
- Jute fibers are extracted from the jute plants through retting and stripping.
- Silk fibers are obtained by unraveling the silk cocoons and spinning the fine threads.
- Wool fibers are sheared from sheep and then processed to remove impurities.
4. Manufacturing Process:
- Once the raw materials are processed into fibers, they are further processed to make yarns and fabrics.
- Yarns are produced by spinning the fibers together, which can be done through various techniques.
- Fabrics are created by weaving or knitting the yarns together to form textiles.
5. Final Products:
- The textile industry produces a wide range of products, including clothing, home textiles, industrial textiles, and technical textiles.
- Clothing includes garments such as shirts, dresses, pants, and jackets.
- Home textiles include bed sheets, curtains, towels, and upholstery fabrics.
- Industrial textiles are used in sectors like automotive, aviation, and construction.
- Technical textiles are specialized fabrics used for purposes like filtration, protection, and medical applications.
In conclusion, the textile industry is an example of an agro-based industry because it uses agricultural raw materials like cotton, jute, silk, and wool to produce a wide range of textiles and finished goods. This industry plays a significant role in the economy, utilizing natural fibers derived from crops and adding value to the agricultural sector.

What is the major cause of thermal pollution?

Detailed Solution: Question 9

Explanation:
Thermal pollution mainly occurs when industries—especially nuclear and thermal power plants—discharge hot water or steam into nearby water bodies. This sudden temperature rise reduces oxygen levels, affecting aquatic life. Therefore, wastes (heated effluents) from power plants are the major cause of thermal pollution.

  • Thermal pollution = an increase in the temperature of water bodies
  • Major contributor = Power plants (especially nuclear and thermal)
  • Other options cause different types of pollution (chemical, air, or biological), not thermal.
