Geography of Maharashtra

Geography of Maharashtra

Overview

Maharashtra is India's third-largest state by area (307,713 sq km) and second-largest by population. For MAHA TET Paper II Social Studies, questions on Maharashtra's geography test your knowledge of its physical divisions, major rivers, climate patterns, and natural resources. This topic connects directly to Environmental Studies themes and often appears alongside questions on Maharashtra's economy and culture.

Candidates must visualise Maharashtra's location (western India, bounded by Gujarat, Madhya Pradesh, Chhattisgarh, Telangana, Karnataka, Goa, and the Arabian Sea) and understand how its physical features influence agriculture, settlement, and livelihoods.

Key Concepts

• Three major physical divisions: Maharashtra is divided into the Konkan coastal plain (west), the Sahyadri mountain range (Western Ghats), and the Deccan Plateau (east). Each has distinct landforms, soil, and climate.
• Western Ghats (Sahyadri): A continuous mountain range running north-south along the western edge; average height 1,000–1,200 m. Key peaks include Kalsubai (1,646 m, highest in Maharashtra), Salher, Harishchandragad, and Mahabaleshwar.
• Deccan Plateau: Covers most of eastern Maharashtra; composed of Deccan Trap basalt from ancient lava flows. Characterised by flat-topped hills, black (regur) soil ideal for cotton, and low rainfall.
• Konkan Coast: Narrow coastal strip between the Arabian Sea and Sahyadris; width 30–60 km. Receives heavy monsoon rainfall; rice, coconut, and mango are major crops.
• River systems: Most rivers originate in the Western Ghats and flow eastward into the Bay of Bengal. The Godavari ("Dakshin Ganga") and Krishna are the two longest. Westward-flowing rivers are short and swift.
• Monsoon climate: Maharashtra has a tropical monsoon climate. The southwest monsoon (June–September) brings 80% of annual rainfall; the Konkan receives over 2,500 mm while Vidarbha receives only 800–1,000 mm.
• Soil types: Black soil (regur) dominates the plateau; laterite soil in the Konkan and Sahyadri foothills; alluvial soil along river valleys.
• Natural resources: Rich in coal (Chandrapur, Nagpur), manganese (Bhandara, Nagpur), bauxite (Kolhapur, Ratnagiri), iron ore, and limestone. Forests cover about 17% of the state area.

Formulas / Key Facts

Worked Examples

Example 1 — Physical Divisions

Question: Name the three physical divisions of Maharashtra from west to east.

Solution:

1. Konkan Coastal Plain — low-lying, narrow strip along Arabian Sea
2. Sahyadri Range (Western Ghats) — mountain barrier running north-south
3. Deccan Plateau — vast interior tableland covering Marathwada and Vidarbha

Example 2 — River Direction

Question: Why do most rivers of Maharashtra flow eastward?

Solution:

• The Western Ghats form the main watershed near the western coast.
• The general slope of the Deccan Plateau is from west to east.
• Therefore, rivers like Godavari, Bhima, and Krishna originate in the Sahyadris and flow eastward toward the Bay of Bengal.
• Only small, swift streams flow westward into the Arabian Sea because the distance to the sea is short.

Example 3 — Rainfall Distribution

Question: Explain why Vidarbha receives less rainfall than Konkan.

Solution:

• The southwest monsoon winds first strike the Konkan coast and Sahyadri range.
• The mountains force the moist air to rise, causing heavy orographic rainfall on the windward (western) side.
• By the time the winds cross the Sahyadris, they have lost most moisture.
• Vidarbha lies in the rain-shadow region on the leeward (eastern) side, receiving only 800–1,000 mm annually compared to 2,500–6,000 mm in Konkan.

Common Mistakes

• Confusing Godavari with westward rivers → Godavari is the longest river in peninsular India and flows eastward, not westward. Remember: "Godavari goes to the Bay of Bengal."
• Thinking Kalsubai is in the Konkan → Kalsubai is in the Sahyadri range in Ahmednagar district, not on the coastal plain.
• Assuming uniform rainfall across Maharashtra → Rainfall varies dramatically: over 5,000 mm at Mahabaleshwar versus under 500 mm in parts of Solapur. Always mention the rain-shadow effect.
• Mixing up soil types → Black soil (regur) is found on the Deccan Plateau (cotton belt); laterite soil is in the Konkan and hilly areas (not suitable for most crops without treatment).
• Forgetting Vidarbha's resources → Vidarbha (Nagpur, Chandrapur, Bhandara) is the main mineral belt of Maharashtra — coal, manganese, and iron ore. Don't associate all resources with western Maharashtra.

Quick Reference

• Three divisions: Konkan → Sahyadri → Deccan Plateau (west to east)
• Highest point: Kalsubai, 1,646 m, Ahmednagar
• Major rivers east: Godavari, Krishna, Bhima, Wardha, Wainganga
• Major rivers west: Ulhas, Vashishti, Savitri (short and swift)
• Rainfall: Konkan 2,500+ mm; Vidarbha ~900 mm; rain-shadow effect east of Sahyadris
• Key minerals: Coal (Chandrapur), manganese (Bhandara), bauxite (Kolhapur/Ratnagiri)
