Geography of Jharkhand

Overview

Jharkhand, carved out of Bihar on 15 November 2000, occupies a distinctive position in India's physical geography. The state is dominated by the **Chota Nagpur Plateau**, one of the oldest geological formations on Earth, which gives Jharkhand its characteristic undulating terrain, mineral wealth, and unique drainage patterns. For JTET Paper I (EVS), this topic connects directly to the NCF emphasis on "local environment" — students should understand their immediate geographical surroundings before expanding to national and global contexts.

Exam questions typically test factual recall (names of rivers, plateau divisions, forest types) and application-based understanding (why Jharkhand has mineral wealth, how rivers affect tribal settlements). Mastery requires knowing the physical features, the major river systems, and the forest cover that shapes the state's ecology and livelihoods.

Key Concepts

• **Chota Nagpur Plateau** is a continental plateau (Gondwana landmass remnant), covering most of Jharkhand. It is NOT a volcanic or coastal plateau — this distinction matters for understanding soil and mineral formation.

• The plateau is divided into **four sub-regions**: Ranchi Plateau (central, highest), Hazaribagh Plateau (north), Rajmahal Hills (northeast, basaltic), and the Kolhan region (southwest, lower elevation).
