Q312. Which of the following pairs of sugar-producing crops and their climatic preference is incorrectly matched?
Explanation
Sugarcane is a tropical and subtropical crop that is highly sensitive to frost; even a short freeze can damage the plant and reduce its sugar content. In contrast, sugar beet is well-adapted to cool temperate climates and is a major source of sugar in those regions. Statement three is incorrect because frost-prone continental climates are unsuitable for sugarcane growing needs.
Q313. Given below are two statements regarding tea cultivation:
Statement I: Tea bushes require an acidic, well-drained soil and high rainfall evenly distributed throughout the year.
Statement II: Stagnant water around the roots of the tea plant is highly beneficial for the growth of tender leaves.
Which of the following is correct?
Statement I: Tea bushes require an acidic, well-drained soil and high rainfall evenly distributed throughout the year.
Statement II: Stagnant water around the roots of the tea plant is highly beneficial for the growth of tender leaves.
Which of the following is correct?
Explanation
Tea bushes require acidic, well-drained soil and high rainfall that is evenly distributed throughout the year to promote continuous growth of tender leaves. However, stagnant water is highly damaging as it can cause root rot; therefore, tea is often grown on hill slopes to ensure natural drainage. Statement two is incorrect because the plant cannot tolerate waterlogging in its roots.
Q314. Which of the following statements about the distribution and production of Jute is incorrect?
Explanation
Jute is a tropical fiber crop that requires high temperatures and heavy rainfall throughout its growth cycle. It thrives in humid conditions and fertile alluvial soils, particularly in the delta regions of India and Bangladesh. The claim that it requires a cool and dry climate is incorrect, as such conditions would stunt the plant’s growth. Harvesting jute requires significant manual labor.
Q315. Which of the following farming systems is the odd one out in terms of its primary reliance on chemical fertilizers and advanced mechanization?
Explanation
Primitive subsistence agriculture relies on traditional tools, manual labor, and natural soil fertility rather than modern industrial inputs. In contrast, commercial grain farming, dairy farming, and modern mixed farming are characterized by high levels of mechanization and the application of chemical fertilizers. This fundamental difference in technological intensity separates primitive farming from the advanced, profit-oriented agricultural systems that dominate global trade.
Q316. Regarding plantation agriculture, which of the following is NOT typically considered a plantation crop?
Explanation
Plantation agriculture is a specialized commercial system focusing on the large-scale production of a single cash crop, such as rubber, coffee, tea, or sugarcane, primarily for export. These crops are usually grown on large estates in tropical regions. Wheat, however, is a cereal grain typically grown in extensive commercial grain farming or subsistence systems. It is not managed under plantations.
Q317. What is the main effect of inadequate drainage in heavily irrigated farming regions, such as parts of the Indira Gandhi Canal command area in Rajasthan?
Explanation
In heavily irrigated regions with poor drainage, the water table can rise to the surface, causing waterlogging. This inhibits plant growth by depriving roots of oxygen. Additionally, as water evaporates from the soil surface, it leaves behind dissolved salts, leading to secondary salinization. This process degrades soil quality and can eventually render the land unproductive, as seen in parts of northwestern Rajasthan.
Q318. Which cereal crop ranks first in the world in terms of total geographical area under cultivation and acts as a staple food for a large portion of the global population, especially in temperate zones?
Explanation
Wheat is the world’s most widely cultivated cereal crop in terms of total geographical area. It serves as a primary staple food for a large portion of the global population, particularly in the temperate regions of Europe, North America, and Asia. Its versatility and ability to grow in varied environments make it a cornerstone of global food security and international agricultural trade.
Q319. Which of the following agricultural practices is the most appropriate and sustainable approach for maintaining soil fertility in mixed farming systems?
Explanation
The most sustainable way to maintain soil fertility in mixed farming is through crop rotation that incorporates leguminous plants like clover or alfalfa. These crops naturally enrich the soil with nitrogen. This practice, combined with the application of animal manure from livestock, reduces the need for synthetic fertilizers. It ensures long-term agricultural productivity while supporting the livestock component of the farm system.
Q320. Which of the following factors is considered the most critical for determining the location of an industry that uses a highly weight-losing raw material?
Explanation
Weight-losing raw materials significantly reduce in bulk or weight during the manufacturing process, making transportation of the finished product much cheaper than the raw material itself. To minimize total transportation costs and enhance economic efficiency, industries like iron smelting or sugar manufacturing are strategically located near the sources of these heavy and bulky materials to reduce haulage expenses.Answer key for these questions

Key facts from World Geography
- The RPSC syllabus for world geography lists mountains, plateaus, plains and deserts, major rivers and lakes, natural vegetation, agriculture, industrial regions, transport and environmental issues.
- Questions ask for the location of a feature: where a range lies, where a river ends, which country has an industrial region.
- Statement and sequence questions are common, for example the order of mountain ranges or of vegetation layers.
- Environmental issues are asked through treaties and dates, such as the Montreal Protocol, the IPCC and the Paris Agreement.
- Indian and Rajasthan geography are on their own pages, each with its own chapters.
Frequently asked questions
How many RAS Prelims practice MCQs are there on World Geography?
This page has 553 practice MCQs on World Geography. Each has the correct answer, and most have an explanation.
Which chapters does the world geography set cover?
Seven chapters: physical landforms (mountains, plateaus, plains and deserts), major rivers and lakes, natural vegetation and biomes, world agriculture, major industrial regions, the world transport network, and environmental issues including desertification, deforestation, climate change and ozone depletion.
Is world geography part of the RAS Prelims syllabus?
Yes. The RPSC syllabus has a Geography of World and India section that lists physical aspects, rivers and lakes, natural vegetation, agriculture, industrial regions, transport and environmental issues for the world, followed by India and Rajasthan.
How can I revise world geography quickly?
Use an atlas alongside the questions. Attempt each chapter, read the explanation for every miss and mark the place on the map. Make short lists of ranges, rivers and industrial regions with their countries, and revise them over several days.
