Geography as a Discipline: Assertions & Reason Type Questions

Read the case study given below and answer any three questions that follow.
All the branches of physical geography have interface with natural sciences. The traditional physical geography is linked with geology, meteorology, hydrology and pedology; thus, geomorphology, climatology, oceanography and  soil geography, respectively, have very close link with the natural sciences as they derive their data from these sciences. Bio-geography is closely related to botany and zoology as well as ecology as human beings are located in different locational niche. A geographer should have some proficiency in mathematics and art, particularly in drawing maps. Geography is very much linked with the study of astronomical locations and deals with latitudes and longitudes. The shape of the earth is geoid, but the basic tool of a geographer is a map that is a two-dimensional representation of the earth. The problem of converting geoids into two dimensions can be tackled by projections constructed graphically or mathematically. The cartographic and quantitative techniques require sufficient proficiency in mathematics, statistics and econometrics. Maps are prepared through artistic imagination. Making sketches, mental maps and cartographic work requires proficiency in arts. 

Question 1: Making sketches, mental maps and cartographic work requires proficiency in _________.
(a) geography
(b) english
(c) arts
(d) subject

Ans: (c)

Explanation: Cartographic work, sketches and mental maps need artistic skills such as accurate drawing, use of symbols, colour, shading, sense of proportion and spatial imagination. These skills fall under the arts, which help geographers to represent three-dimensional features on two-dimensional maps clearly and effectively.

Question 2: The problem of converting geoids into two dimensions can be tackled by projections constructed:
(a) graphically
(b) mathematically
(c) Both (a) and (b)
(d) mentally

Ans: (c)

Explanation: Converting the curved shape of the Earth (geoid) to a flat map is achieved through map projections. These projections may be constructed graphically or mathematically. Graphical methods use geometric drawing techniques, while mathematical methods use formulae to transform spherical coordinates into a plane; both approaches aim to manage and distribute distortion in a controlled way.

Question 3: Which science is closely related to botany and zoology as well as ecology?
(a) Climatology
(b) Bio-geography
(c) Oceanography
(d) None of the above

Ans: (b)

Explanation: Bio-geography studies the distribution of plants and animals across space and time and their relationships with the environment. It therefore draws directly on botany (the study of plants), zoology (the study of animals) and ecology (the study of organisms and their interactions). For example, botanical knowledge helps classify vegetation types that bio-geographers map and analyse.

Question 4: All the branches of physical geography have interface with:
(a) natural sciences
(b) physical sciences
(c) social sciences
(d) political sciences

Ans: (a)

Explanation: Traditional branches of physical geography such as geomorphology, climatology, oceanography and soil geography rely on data and principles from the natural sciences - for example, geology, meteorology, hydrology and pedology. These links show that physical geography interfaces closely with the natural sciences to study Earth's processes and forms.

Read the case study given below and answer any three questions that follow.
Physical geography includes the study of lithosphere (landforms, drainage, relief and physiography), atmosphere (its composition, structure, elements and controls of weather and climate; temperature, pressure, winds, precipitation, climatic types, etc.), hydrosphere (oceans, seas, lakes and associated features with water realm) and biosphere (life forms including human beings and macro-organisms and their sustaining mechanism, viz. food chain, ecological parameters and ecological balance). Soils are formed through the process of pedogenesis and depend upon the parent rocks, climate, biological activity and time. Time provides maturity to soils and helps in the development of soil profiles. Each element is important for human beings. 
Landforms provide the base on which human activities are located. The plains are utilised for agriculture. Plateaus provide forests and minerals. Mountains provide pastures, forests and tourist spots and are sources of rivers providing water to lowlands. Climate influences our house types, clothing and food habits. The climate has a profound effect on vegetation, cropping pattern, livestock farming and some industries, etc. Human beings have developed technologies that modify climatic elements in a restricted space such as air conditioners and coolers. Temperature and precipitation ensure the density of forests and quality of grasslands. In India, monsoonal rainfall sets the agriculture rhythm in motion. Precipitation recharges the ground water aquifers, which later provides water for agriculture and domestic use.          

Question 5: What has a profound effect on vegetation, cropping pattern, livestock farming and some industries?
(a) Politics
(b) Climate
(c) Population
(d) Economy

Ans: (b)

Explanation: Climate - especially temperature and rainfall patterns - strongly influences vegetation types, the choice of crops, the kind of livestock that can be reared, and some industries (for example, those reliant on water or particular climatic conditions). In India, monsoonal rainfall largely determines agricultural cycles; changes in climate or extreme events can therefore affect food production and livelihoods.

Question 6: Landform provides the base on which human activities are located.
(a) True
(b) False
(c) Somewhat true
(d) None of the above 

Ans: True

Explanation: Landforms determine where people settle and what activities they pursue. For example, plains are favoured for agriculture and transport because of flat terrain, plateaus may supply minerals and forests, and mountains provide pastures, forests, tourism sites and sources of rivers. Thus landforms form the physical base for many human activities.

Question 7: What recharges the ground aquifers, which later later provides water for agriculture and domestic use?
(a) Dams
(b) Borewells
(c) Precipitation
(d) Humidity

Ans: (c)

Explanation: Precipitation (rain and snowmelt) is the main natural source that recharges groundwater aquifers. Surface water from rivers and lakes can also contribute. Human actions that reduce infiltration - such as soil erosion or extensive sealing of the ground - reduce recharge and increase surface runoff.

Question 8: What ensures the density of forests and quality of grasslands?
(a) Temperature and climate
(b) Precipitation and moisture
(c) Moisture and temperature
(d) Temperature and precipitation 

Ans: (d)

Explanation: Both temperature and precipitation together determine the type and density of vegetation. Adequate rainfall and suitable temperatures support dense forests, while different combinations of these factors produce grasslands of varying quality. Thus the interaction of temperature and precipitation shapes vegetation patterns.

Geography is an interdisciplinary subject of study. The study of every subject is done according to some approach. The major approaches to study geography have been (i) Systematic and (ii) Regional. The systematic geography approach is the same as that of general geography. This approach was introduced by Alexander Von Humboldt, a German geographer (1769-1859) while the regional geography approach was developed by another German geographer and a contemporary of Humboldt, Karl Ritter (1779- 1859). In the systematic approach, a phenomenon is studied world over as a whole, and then the identification of typologies or spatial patterns is done. For example, if one is interested in studying about natural vegetation, the study will be done at the world level as a first step. The typologies such as equatorial rainforests or softwood conical forests or monsoon forests, etc. will be identified, discussed and delimited. In the regional approach, the world is divided into regions at different hierarchical levels, and then all the geographical phenomena in a particular region are studied. These regions may be natural, political or designated regions. The phenomena in a region are studied in a holistic manner searching for unity in diversity.  

Question 9: The phenomena in a region are studied in a ________ manner searching for unity in diversity.
(a) proper
(b) holistic
(c) systematic
(d) None of the above  

Ans: (b)

Explanation: In the regional approach, all geographical phenomena within a region are studied together in a holistic manner. This means examining physical, biological and human features collectively to understand the unity and diversity of the region.

Question 10: In the regional approach, the world is divided into regions at different hierarchical levels.
(a) True
(b) False
(c) Partially true
(d) Partially false

Ans: True

Explanation: The regional approach organises the world into regions at various hierarchical levels (for example, local, national, continental). These regions may be natural, political or designated, and studying them at different scales helps examine spatial patterns and processes specific to each region.

Question 11: What is geography?
(a) It is an interdisciplinary subject of study.
(b) It is a spatial subject of study.
(c) It is an independent subject of study.
(d) It is a hierarchical subject of study.

Ans: (a)

Explanation: Geography is an interdisciplinary subject that studies the Earth's physical features and atmosphere and how human activities affect and are affected by these features. It covers the distribution of populations, resources and economic and political activities, drawing on many other disciplines for data and methods.

Question 12: The __________ geography approach is the same as that of general geography.
(a) regional
(b) systematic
(c) human
(d) historical

Ans: (b)

Explanation: The systematic geography approach studies individual geographical phenomena (such as climate, vegetation or soils) across the world and is thus the same as general geography. This approach was popularised by Alexander von Humboldt, while the regional approach was developed by Karl Ritter.
