The question asks to classify transport, which provides mobility, into one of the economic activity sectors. Understanding the characteristics of each sector (primary, secondary, tertiary, quaternary) is key to correctly identifying where transport services fit.
Correct Option: C) A tertiary activity
Transport is a classic example of a tertiary activity because it provides a service (mobility) rather than producing a tangible good or extracting raw materials. It supports the movement of goods from primary and secondary sectors and allows people to access various services and workplaces.
The question asks to identify the three principal modes of transportation as classified in human geography. This requires knowledge of the fundamental categories used to describe how people and goods move across different environments.
B) Land, water and air are the three principal modes of transportation. Land transport includes roads and railways, water transport includes oceans, rivers, and canals, and air transport involves aircraft. These are the most fundamental and comprehensive categories.
The question asks about the primary use case for ropeways and cableways, especially for moving goods like minerals. The key is to identify the terrain where these transport systems offer a significant advantage over conventional methods.
A) Steep mountain slopes and mining areas unsuitable for ordinary road construction. This option perfectly aligns with the advantages of ropeways and cableways. They can traverse difficult terrain, cross valleys, and climb steep slopes where constructing roads or railways would be prohibitively expensive, technically challenging, or environmentally damaging. This makes them highly suitable for transporting bulk materials like minerals from mines located in mountainous or rugged regions.
The question asks to identify the mode of transport that is most economical for short distances and offers door-to-door service, which is a key advantage for freight movement. We need to evaluate each option based on these two criteria.
Correct Option: A) Road transport is generally the most economical for short distances due to its flexibility and lower initial setup costs for individual routes. Its primary advantage in freight movement is its ability to provide door-to-door service, eliminating the need for trans-shipment at intermediate points.
The question asks for the best description of "metalled roads" as distinguished from "unmetalled roads". This requires understanding the common definitions and characteristics of different types of roads used in geography and infrastructure studies.
D) All-weather roads built with a hard surface that remain serviceable in almost every season
This option accurately describes metalled roads. The term "metalled" implies a constructed, hard surface (like tar, concrete, or compacted stone) that allows the road to withstand various weather conditions, making it an all-weather road. Unmetalled roads, conversely, are typically kachcha (dirt) roads that become unusable during rainy seasons.
The question asks to identify the country with the highest density of railway network among the given major countries. Railway network density is typically calculated as the total length of railway lines divided by the country's land area. We need to compare the railway infrastructure of the listed countries.
D) United States of America — The United States has one of the most extensive and dense railway networks among the world's major countries, especially when considering its large land area. Its railway system is crucial for freight transport and plays a significant role in its economy.
