1 Mark Each | Total: 10 Marks | Choose the correct option
Section B: Short Answer Questions
2 Marks Each | Total: 20 Marks | Write 2-3 sentences with examples
- Weather = Short-term, changeable
- Climate = Long-term, stable
- Same elements but different time scales
- Seasonal wind reversal
- Winter: dry northeast winds
- Summer: wet southwest winds
- Extreme temperatures far from sea
- Sea moderates temperature
- No moderation = Extreme weather
- Not continuous rainfall
- Alternating wet & dry spells
- Unpredictable farming impact
- Clear, dry, cool season
- Temperature gradient S to N
- Important mahawat rainfall
- Hot, dry summer wind
- Northern India
- Dangerous effects
1. Latitude: Tropic of Cancer divides India into tropical (south) and subtropical (north) zones
2. Altitude: Himalayas are 6,000m high and much cooler; coastal areas are flat
3. Distance from Sea: Interior areas have extreme temperatures; coastal areas are moderate
4. Relief Features: Mountains block winds and force precipitation
- Any two with explanation
- Must relate to India's climate
- Blocks cold winds
- Moderate winters
- Forces rainfall
- Creates rain shadow
- Winter rainfall in north
- Small amount but crucial
- Grows rabi crops (wheat, gram)
Rajasthan: Receives less than 60 cm rainfall annually (one of driest regions); receives scanty rainfall during monsoon; lies in rain shadow area of Western Ghats.
Reason: Western coast faces monsoon winds directly; Rajasthan is far from monsoon influence and in rain shadow.
Section C: Long Answer Questions
5 Marks Each | Total: 30 Marks | Write 150-200 words
1. LATITUDE: Distance from Equator. Places closer receive more direct solar energy (hot), poles receive slanted rays (cold).
2. ALTITUDE: Height above sea level. Increases in altitude = decreases in temperature (~6.5°C per 1000m). Himalayas (6,000m) much cooler than plains.
3. PRESSURE & WIND SYSTEMS: Determine wind direction and rainfall patterns. Control pressure belts and wind systems.
4. DISTANCE FROM SEA: Sea moderates temperature due to high heat capacity. Interior areas far from sea experience extreme temperatures. Coastal areas remain moderate year-round.
5. OCEAN CURRENTS: Warm currents heat coastal areas; cold currents cool them.
6. RELIEF FEATURES: Mountains block winds, force precipitation on windward slopes. Leeward side remains dry (rain shadow).
How they work together: These controls interact to create climate. India's example: Its latitude creates tropical-subtropical climate. Himalayas (altitude + relief) block cold winds and force monsoon rains. Sea moderates coastal areas. Together = unique monsoon climate with regional variations.
Step-by-step (By early June):
1. LOW-PRESSURE: Forms over interior Asia and NW India due to intense heating
2. HIGH-PRESSURE OVER OCEAN: Exists over cool southern Indian Ocean
3. PRESSURE GRADIENT: Creates air movement from high to low pressure
4. WIND DEFLECTION: Earth's rotation deflects winds right (northern hemisphere) = southwesterly direction
5. MOISTURE: Winds blow over warm Indian Ocean, gather abundant moisture
6. RAINFALL: Moisture-laden winds hit landmass bringing widespread rainfall
Rainfall Distribution:
• Western Ghats windward: 250+ cm
• Northeast: Highest rainfall
• Ganga Valley: Moderate
• Rajasthan: Scanty (rain shadow)
Brings 90% of annual rainfall in 4 months. Unpredictable "breaks" cause wet-dry spells. Crucial for agriculture and water cycle.
1. AGRICULTURAL CALENDAR: Every farmer from north to south plans agricultural year around monsoon. Sowing June-July, harvesting after. From Punjab to Tamil Nadu—all follow monsoon pattern.
2. WATER RESOURCES: Monsoon fills rivers (Godavari, Krishna, Ganges) and reservoirs providing water for 1.4 billion people. Without monsoon, entire water cycle fails.
3. ANIMAL & PLANT LIFE: Animals dormant before monsoon; plants bloom when rains come. Entire ecosystems revolve around monsoon.
4. FESTIVALS: Most Indian festivals tied to seasonal cycles controlled by monsoon. Pongal (TN), Onam (Kerala), harvest festivals—all celebrate monsoon-dependent crops.
5. CULTURAL LIFE: Monsoon influences what people wear, eat, and do. Creates shared seasonal experiences across diverse regions.
REMARKABLE: From Kashmir to Kanyakumari—people eagerly await same monsoon that brings hope and prosperity to entire nation. It's the lifeline binding diverse India into one.
Extreme Highs: Rajasthan 50°C (hottest), Gujarat 42-45°C
Extreme Lows: Drass -45°C (coldest), Leh below freezing, Kashmir snowfall
Moderate: Thiruvananthapuram 22-27°C year-round, coastal areas moderate
Diurnal: Thar Desert 50°C day → 15°C night (35° difference!)
RAINFALL VARIATIONS:
Wettest: Mawsynram 400+ cm (world's highest), Western Ghats 250+ cm, Northeast 200+ cm
Driest: Rajasthan <60 cm, Ladakh <10 cm
Seasonal: North 90% in monsoon; Tamil Nadu maximum in retreating monsoon
REASONS:
• Latitude: Tropical south, subtropical north
• Altitude: Himalayas cold, plains warm
• Distance from Sea: Interior hot, coastal moderate
• Wind Patterns: Monsoon brings rain to windward slopes
• Relief: Mountains create rain shadow
India's climate incredibly diverse—from wettest (Mawsynram) to driest (Ladakh), coldest (Drass) to hottest (Rajasthan)—yet monsoon provides underlying unity.
Duration: 4 months | Wind: Southwest, consistent | Rainfall: Heavy, 90% annual
Characteristics: Strong winds (30 km/hr), high humidity, overcast, cool temps, covers country in ~1 month
Distribution: Western Ghats 250+ cm, Northeast highest, Central moderate, Rajasthan scanty
Features: "Breaks" (wet-dry spells), unpredictable, can cause floods
RETREATING MONSOON (October-November):
Duration: 2 months | Wind: Weakening southwest | Rainfall: Cyclonic, mainly east coast
Characteristics: Weakening winds, still humid but drying, transition season, warming, clear skies gradually return
Distribution: Coromandel coast maximum, eastern deltas heavy, rest becomes dry
Features: Tropical cyclones and depressions, destructive, causes floods in deltas
SIMILARITIES: Both monsoon system parts | Bring significant rainfall | Can cause natural disasters | Affect agriculture
DIFFERENCES: Duration different | Rainfall distribution: advancing widespread, retreating coastal | Weather: advancing cool/wet, retreating warm/drying | Advancing main rain phase, retreating transition phase
Low Rainfall: Rajasthan <60 cm, Ladakh <10 cm, leeward slopes
Monsoon Failure: Prolonged dry spells cause zero rainfall
Variability: High rainfall variability in dry regions
Consequences: Crop failure, groundwater depletion, drinking water scarcity
FLOOD-PRONE AREAS:
High Rainfall: Western Ghats 250+ cm, Northeast 200+ cm
Monsoon Intensity: Strong continuous rainfall causes flooding
River Overflow: Heavy monsoon causes rivers to exceed capacity
Consequences: Damage to crops and life, property destruction
HOW MONSOON CONTRIBUTES:
1. SPATIAL UNEVEN DISTRIBUTION: Excess rain to coasts (floods), minimal to interior (droughts)
2. MONSOON TROUGH: Position shift causes floods in one area, droughts in another
3. "BREAKS" IN MONSOON: Dry spells = drought stress; heavy rain bursts = floods
4. VARIABILITY: Strong one year (floods), weak another (droughts)
5. RAINFALL TIMING: Late arrival = drought; early onset = extended floods
REMARKABLE PARADOX: India experiences both floods AND droughts simultaneously—floods in coastal/western regions while droughts in interior/eastern plateau areas during same period!
Section D: Analysis & Map Questions
5 Marks Each | Total: 10 Marks
Temperature Range: 50°C to -45°C = 95°C difference! (Rajasthan to Drass)
CLIMATE CONTROLS RESPONSIBLE:
1. LATITUDE DIFFERENCE:
Rajasthan 26-27°N receives more direct sun rays
Thiruvananthapuram 8°N (closer to equator) gets constant heat
→ Thiruvananthapuram warmer in winter
2. ALTITUDE VARIATION:
Pahalgam: High altitude (mountain valley) → Lower temperature
Drass: 3,500m altitude (ultra-high) → Coldest place
Thiruvananthapuram: Sea level → Moderate temperature
→ Temperature decreases ~6.5°C per 1000m
3. DISTANCE FROM SEA (CONTINENTALITY):
Rajasthan: Interior, far from sea → Extreme temperatures (50°C no moderation)
Thiruvananthapuram: Coastal → Sea moderates year-round (22-27°C)
Pahalgam: Kashmir Valley → Some sea influence
4. HIMALAYAN BARRIER:
Drass & Pahalgam: Behind Himalayas
Himalayas block cold winds but ultra-high altitude dominates
Drass extreme cold due to altitude
5. WIND PATTERNS:
Thiruvananthapuram: Tropical winds, warm ocean breezes
Rajasthan: Dry winds, no ocean moderation
CONCLUSION: India shows world's extreme temperature ranges within one country! All 5 climate controls work together to create this 95°C difference.
