Industries

Step 1: The assertion is correct: Mumbai’s humid climate is ideal for the cotton textile industry, as humidity prevents cotton threads from drying out and breaking during spinning and weaving.
Step 2: The reason is correct: Mumbai’s coastal location near the Arabian Sea results in a humid climate.
The reason explains the assertion, as the proximity to the sea directly contributes to the humidity that supports the textile industry.

Step 1: The assertion is correct: Geographical location is necessary to define an area, as it determines its coordinates, climate, and resources, shaping its identity.
Step 2: The reason is incorrect: Geographical location significantly affects regional development by influencing climate, resource availability, trade routes, and economic activities (e.
g.
, coastal ports vs.
inland deserts).
Since the reason is false, it cannot explain the assertion.

Step 1: The cotton textile industry in Mumbai thrives due to specific conditions.
- (b) Humid climate: Prevents thread breakage during spinning/weaving.
- (c) Market: Large local and export markets support demand.
- (d) Supply of labour: Abundant skilled/unskilled labor in Mumbai.
Step 2: Mineral (a) is incorrect, as the cotton textile industry relies on cotton (an agricultural product), not minerals, unlike industries like steel.

Agro-based industries are those that rely mainly on agricultural products as raw materials. An example of such an industry is the sugar industry, which processes sugarcane or sugar beets. In contrast, industries like iron and steel, chemicals, and cement are based on non-agricultural raw materials.

Step 1: Understand footloose industries.
Footloose industries are industries that are not dependent on specific locations or resources. They can be set up anywhere because they do not rely on local resources like raw materials or power. Step 2: Analyze each option.
- Option (a): Cement industries are usually location-bound due to the need for raw materials like limestone. - Option (b): Clock-making industries typically require skilled labor but are not completely footloose. - Option (c): Diamond cutting industries are a perfect example of footloose industries, as they can be established anywhere, mainly due to the high value of the product and the low weight-to-value ratio. - Option (d): Hairpin making industries may require labor but do not depend on a specific location or resource. Final Answer: The correct answer is (c) Diamond cutting industries.

Concept: The location of industries is influenced by several physical factors related to natural resources and environmental conditions. These factors help industries operate efficiently by ensuring the availability of essential resources.
Step 1:Availability of raw materials.
Industries are often located near sources of raw materials to reduce transportation costs and ensure a continuous supply. For example, iron and steel industries are usually located near iron ore and coal deposits.
Step 2:Availability of water.
Many industries require large quantities of water for processing, cooling, and cleaning. Therefore, industries are commonly located near rivers, lakes, or other reliable water sources.
Step 3:Climate conditions.
Certain industries require specific climatic conditions for efficient production. For example, textile industries benefit from humid climates, which help prevent the breaking of threads.
Step 4:Availability of land.
Industries need adequate land for setting up factories, storage facilities, and infrastructure. Flat and accessible land is generally preferred for industrial development.
