Geography (PGT) – HTET Level 3 Study Notes

Overview

Geography at the PGT level for HTET covers a comprehensive understanding of Physical, Human, and Economic Geography. This subject is crucial for teaching Classes IX-XII and forms a significant portion of the Level 3 examination. Candidates must demonstrate mastery over both theoretical concepts and their practical applications.

The syllabus integrates global perspectives with Indian and Haryana-specific content. Questions typically test conceptual clarity, map-based knowledge, and the ability to connect geographical phenomena with real-world issues like urbanisation, resource management, and climate change. Strong command over this subject also helps in the Haryana GK section, as state geography overlaps considerably.

Students should focus on understanding processes (not just memorising facts), interpreting diagrams and maps, and connecting physical phenomena to human activities. Around 40-50% of questions come from Physical Geography, 30-35% from Human Geography, and 20-25% from Economic Geography.

Key Concepts

• **Geomorphology** – The study of landforms and processes shaping the Earth's surface. Key agents: running water, glaciers, wind, waves, and groundwater. Each creates distinct erosional and depositional features.

• **Climatology** – Understanding atmospheric processes, pressure belts, wind systems, and climate classification (Koeppen and Thornthwaite). India's monsoon mechanism is a must-know topic.

• **Oceanography** – Ocean floor relief, salinity, temperature distribution, ocean currents, and their influence on climate (El Niño, La Niña effects).

• **Population Geography** – Distribution, density, growth, migration theories (Ravenstein's Laws), demographic transition model, and population policies.

• **Settlement Geography** – Rural vs urban settlements, urban morphology, central place theory (Christaller), and urbanisation trends in India.

• **Economic Activities** – Primary (agriculture, mining), secondary (manufacturing), tertiary (services), quaternary and quinary sectors. Von Thünen's agricultural location theory and Weber's industrial location theory.

• **Resource Geography** – Classification of resources, conservation strategies, and sustainable development. Focus on Indian mineral and energy resources.

• **Regional Planning** – Concept of region, regionalisation, growth pole theory, and planning regions in India.

Formulas / Key Facts

**Physical Geography:**

• Lapse rate of temperature: 6.5°C per 1000 metres (normal lapse rate)
• Coriolis effect deflects winds: right in Northern Hemisphere, left in Southern Hemisphere
• Major ocean currents: Gulf Stream (warm, Atlantic), Labrador (cold), Kuroshio (warm, Pacific)
• India receives 75-90% of annual rainfall from South-West Monsoon (June-September)
• Highest rainfall in India: Mawsynram (Meghalaya) – approx. 11,872 mm annually

**Human Geography:**

• Demographic Transition Model: 4 stages – high stationary, early expanding, late expanding, low stationary
• India's population density (Census 2011): 382 persons per sq km
• Haryana population density (2011): 573 persons per sq km
• Urbanisation in India (2011): 31.16%
• Haryana urbanisation (2011): 34.88%

**Economic Geography:**

• Green Revolution in India: Started 1966-67, focused on wheat and rice
• India's major industrial regions: Mumbai-Pune, Hooghly, Bengaluru-Chennai, Ahmedabad-Vadodara
• Haryana: Part of Delhi-Gurugram-Faridabad industrial corridor
• Coal reserves: Jharkhand (largest), followed by Odisha, Chhattisgarh
• Iron ore: Jharkhand, Odisha, Chhattisgarh, Karnataka

Worked Examples

**Example 1: Landform Identification**

*Question:* Which depositional landform is created by glaciers in mountainous regions?

*Solution:*

• Glaciers erode valleys creating U-shaped valleys
• As glaciers melt, they deposit material called moraine
• Terminal/end moraine forms at the snout of glacier
• Drumlins are elongated hills of glacial deposits
• **Answer:** Moraines (lateral, medial, terminal) and drumlins are glacial depositional features

**Example 2: Calculation of Population Density**

*Question:* A district has an area of 4,500 sq km and population of 18,00,000. Calculate population density.

*Solution:*

• Population Density = Total Population ÷ Total Area
• = 18,00,000 ÷ 4,500
• = 400 persons per sq km

**Example 3: Industrial Location Theory**

*Question:* According to Weber's theory, where should an industry locate if the weight of raw material is greater than the finished product?

*Solution:*

• Weber's Material Index = Weight of localised raw materials ÷ Weight of finished product
• If Material Index > 1, raw material is heavier
• Industry should locate near raw material source to minimise transport costs
• **Answer:** Near the source of raw material (e.g., iron and steel industry near coal/iron ore mines)

Common Mistakes

**Confusing weather with climate** → Weather is short-term atmospheric condition; climate is the average weather over 30+ years. Questions often test this distinction.

**Mixing up ocean currents** → Students confuse warm and cold currents. Remember: currents moving from equator to poles are warm; poles to equator are cold. Gulf Stream is warm, Labrador is cold.

**Ignoring Haryana-specific geography** → HTET specifically includes Haryana geography. Know that Haryana has two physiographic regions (Shivalik foothills and Indo-Gangetic plain), major rivers (Yamuna, Ghaggar), and agro-climatic zones.

**Treating all monsoons as same** → South-West Monsoon (June-September) brings most rain; North-East Monsoon (October-December) affects only Tamil Nadu coast significantly.

**Confusing growth rate with density** → Growth rate is percentage change in population over time; density is persons per unit area. India's growth rate is declining but density continues to increase.

**Misapplying location theories** → Weber's theory applies to manufacturing industry; Von Thünen's theory applies to agricultural land use around a market centre. Don't interchange them.

Quick Reference

• **Three branches of Geography:** Physical (lithosphere, atmosphere, hydrosphere), Human (population, settlement, culture), Economic (resources, industries, trade)

• **India's climate type (Koeppen):** Mainly Aw (tropical savanna) and Cwg (monsoon with dry winter)

• **Haryana rivers:** Yamuna (eastern boundary), Ghaggar (seasonal, northwest), Markanda, Saraswati (extinct)

• **Demographic dividend:** Large working-age population relative to dependents – India currently experiencing this

• **Sustainable Development Goals (SDGs):** 17 goals adopted in 2015; Geography questions increasingly link to SDG themes

• **Map essentials:** Always remember TONDS – Title, Orientation (north arrow), Neat lines, Date, Scale
