Introduction to Geography

Chapter: 1

FIRST UNIT : GEOGRAPHY AS AN ACADEMIC SUBJECT

IMPORTANT QUESTION AND ANSWER

Answer The Following Questions:

1. What is meant by Geography?

Ans: Geography is the systematic study of the physical, biological, and human-created cultural environments that result from the relationship among the earth’s rotating structure, its form, and its processes.

2. What is meant by the Ancient Period?

Ans: The period from the time of Eratosthenes to around 1250 A.D., spanning nearly one and a half thousand years, when the main objective of geographical studies was to identify and locate natural features that created problems or opportunities for humans, is called the Ancient Period.

3. What are the main components of the atmosphere?

Ans: The main components of the atmosphere are nitrogen and oxygen.

4. What are the branches of Geography?

Ans: The branches of Geography are:

(i) Soil Science.

(ii) Climatology.

(iii) Hydrology.

(iv) Regional Geography.

(v) Social Geography.

5. What does Population and Settlement Geography study?

Ans: Population and Settlement Geography studies birth, death, and growth rates of human beings, migration, the distribution, expansion, and density of rural and urban areas, and the interrelation among these groups.

6. What is the second branch of Geography?

Ans: The second branch of Geography is Human Geography.

7. What are the main approaches of geographical study?

Ans: The main approaches of geographical study are:

(i) Systematic Approach.

(ii) Regional Approach.

8. What is the Biosphere?

Ans: Apart from the non-living elements of nature, the totality of living organisms and their interactions form the Biosphere.

9. From which two Greek words is the English term Geography derived?

Ans: The English term Geography is derived from the Greek words Ge (meaning Earth) and Graphos (meaning Description).

Long Question & Answer:

1. Explain the origin, definition, and field of study of the term “Geography.”

Ans: The word “Geography” is derived from two Sanskrit roots—“Bhu” (Earth) and “Gol” (Spherical). The English term Geography originates from the Greek words geo (‘Earth’) and graphos (‘Description’). It was first used by Eratosthenes (276–194 B.C.). In essence, Geography is the systematic study of the formation, functioning, interrelationship, and outcomes of the physical (mountains, rivers, climate), biological (flora and fauna), and human-made cultural (population, urbanization, economy) environments of the rotating Earth. It seeks to answer the three central questions: “Where?”, “What?”, and “How?”. Thus, it explains spatial diversity by analyzing location, pattern, and cause–effect relationships. Geography integrates natural sciences (Physics, Chemistry, Biology, Geology) with social sciences (Sociology, Economics, Political Science), making it an interdisciplinary and integrative subject often referred to as the “science of synthesis.”

2. What do you mean by the Post-Modern Period?

Ans: The Post-Modern Period in geographical study began around 1950. While retaining all features of the Modern Period, it introduced new methodologies, branches, ideologies, and theories. During this era, the focus shifted toward cause-and-effect analysis and problem-solving. The stages such as problem identification, hypothesis formulation, testing, synthesis, and suggestions gained importance, reflecting the scientific and analytical nature of post-modern geography.

3. What is an Ocean Current? Discuss the causes of its formation.

Ans: An ocean current is a definite and continuous movement of seawater flowing regularly in a specific direction.

Causes of Formation:

(i) Direction and speed of wind.

(ii) Solar heat differences.

(iii) Variation in salinity.

(iv) Coriolis force due to Earth’s rotation.

(v) Tides and gravitational pull.

Because of Earth’s rotation, currents flow clockwise in the Northern Hemisphere and anticlockwise in the Southern Hemisphere. Differences in temperature and salinity create density variations that drive these movements.

4. Differentiate between warm and cold ocean currents with examples.

Ans: Ocean currents are broadly divided into two types:

(i) Warm Currents: These originate from equatorial warm regions and flow toward higher latitudes. They raise the temperature of coastal areas. Example: Kuroshio Current (North Pacific Ocean).

(ii) Cold Currents: These flow from polar regions toward lower latitudes, bringing cold water and reducing coastal temperatures. Example: California Current (flows southward from Alaska).

These currents significantly affect coastal climate, marine life, and navigation.

5. How do ocean currents affect human life and climate?

Ans: Ocean currents have a deep impact on the Earth’s climate, fisheries, navigation, and overall human life.

(i) They regulate the global distribution of heat, balancing temperatures between warm and cold regions.

(ii) Warm currents increase coastal temperatures, while cold currents decrease them.

(iii) They influence rainfall patterns and marine biodiversity.

(iv) Upwelling of nutrient-rich cold water enhances fish production, promoting the fishing industry.

(v) Knowledge of ocean currents helps in planning efficient shipping routes, reducing fuel consumption, and boosting trade.
