Bihar is broadly divided into how many physiographic regions?

Bihar is broadly divided into 4 physiographic regions: the Himalayas, the Indo-Gangetic Plain, the Chota Nagpur Plateau, and the Vindhyan Range.

• The Himalayas are the highest mountain range in the world, and they form the northern border of Bihar. The Himalayas are a major source of water for Bihar, and they also provide a barrier against cold weather from the north.
• The Indo-Gangetic Plain is a vast plain that covers most of northern India and Bangladesh. The Indo-Gangetic Plain is a major agricultural region, and it is also home to most of India’s population.
• The Chota Nagpur Plateau is a plateau that covers much of eastern India. The Chota Nagpur Plateau is a major mineral-rich region, and it is also home to a number of tribal groups.
• The Vindhyan Range is a mountain range that runs through central India. The Vindhyan Range is a major watershed, and it separates the Indo-Gangetic Plain from the Deccan Plateau.

Each of these physiographic regions has its own unique climate, vegetation, and wildlife. The Himalayas are cold and dry, while the Indo-Gangetic Plain is hot and humid. The Chota Nagpur Plateau is a tropical savanna, while the Vindhyan Range is a dry deciduous forest.

Bihar is a diverse state with a rich history and culture. The physiographic regions of Bihar have played a major role in shaping the state’s history and culture.
