This page covers SSC CGL Climate & Soils of India with complete concept notes, 27 graded practice MCQs, key points and exam-specific tips. Free to study.
Core ConceptRead this first — the foundation of the topic
India has eight major soil types
Alluvial, Black (Regur), Red and Yellow, Laterite, Arid/Desert, Saline, Peaty/Marshy, and Forest soils. Each soil type develops due to specific climate conditions
Key Climate-Soil Relationships
Alluvial soils form in river valleys with moderate rainfall (Ganga-Brahmaputra plains). Black soils develop in Deccan plateau with 50-100cm rainfall, perfect for cotton. Red soils form in areas with 50-150cm rainfall and high temperature. Laterite soils develop in heavy rainfall regions (150cm+) like Western Ghats.
Exam PatternsWhat examiners ask — read before attempting PYQs
SSC CGL typically asks 2-3 questions on this topic. Common question types include: soil-crop matching, climate zone identification, monsoon-related facts, and soil distribution maps. Questions often test cause-effect relationships between climate and soil formation.

- ALRLS Method:
A - Alluvial (Rivers, Rice-Wheat)
L - Laterite (Heavy rain, Cashew-Spices)
R - Red (Moderate rain, Millets)
L - Less rain (Arid soils, Cactus)
S - Saline (Coastal, Salt-resistant crops)
Worked ExampleSolve this step-by-step before moving on
1
Step 1
Identify cotton's soil requirement - deep, moisture-retentive, rich in lime and potash
2
Step 2
Match with soil types - Black soil (Regur) has these properties
3
Step 3
Explain climate connection - Black soil forms in Deccan plateau with 50-100cm rainfall
4
Step 4
Add location - Maharashtra, Gujarat, Madhya Pradesh
Answer: Black soil (Regur) is most suitable for cotton because it retains moisture, is rich in lime and potash, and develops in moderate rainfall areas of Deccan plateau.
Exam TrapsCommon mistakes students make — avoid these
Students often confuse laterite soil formation. Remember: Laterite forms due to LEACHING in heavy rainfall areas, making it infertile despite high rainfall. The heavy rain washes away nutrients, leaving only iron and aluminum oxides.
Another frequent error is mixing up alluvial soil types.
Old alluvial (Bangar) is found in higher areas and is less fertile than new alluvial (Khadar) found in flood plains.
For exam success, focus on soil-crop combinations, formation processes, and geographical distribution. Practice map-based questions regularly as they appear frequently in SSC CGL.
