Physiological Division of India (Physiographic Division)

Physiological Division of India

• Physiography is that branch of geography which study is the present relief features of the earth surface.

Physiological Divisions of India

• India is divided into five physiographic divisions –

1. 1. 1. The Himalayan mountains
      2. The great plains of North India
      3. The peninsular plateau
      4. Coastal plain
      5. The Islands

The Himalayas

• Includes the Himalaya Purvanchal and their extension arakan Yoma canon in Myanmar.
• Himalaya forms and natural border between India and Tibet.
• It is youngest and highly unstable land mass of India tectonic movements are very common

Northern Plains

• Also known as Indo gangetic plain.
• Between peninsular and Himalayan region.
• The plains are divided into four belts namely the bhabar belt, the Terai belt, the Bangar belt and the Khadar belt.
• Most useful monotonous region prone to tectonic activities.
• Many rivers flow through this region and develop the relief of this region.

The Peninsular Plateau

• Include centre South India Central India Aravalli Raj Mahal Meghalaya plateau Kutch Kathiawar region etc.
• It is oldest and most stable part of land mass of India.

The Coastal Plains

• Consist of eastern and western coastal plains
• Formed due to consolidation of sediments bought by rivers.
• Highly stable just like peninsular plateau.

The Indian Islands

• India has two major group of Islands namely Andaman and Nicobar and Lakshadweep.
• Lakshadweep group of atoll occupied by coral reefs. No significant volcanic activities are tectonic activities in recent past but is vulnerable to sea level rise.
• Andaman and Nicobar islands are the continuation of Arakan Yomama of Myanmar it has active volcano and tectonically active.

The Thar Desert

• The Indian desert lies towards the western margins of the Aravalli Hills.
• This region gets scanty rainfall which is less than 150 mm in a year, Hence they climate is arid and vegetation is scanty.

So, this was all about the Physiological Division of India (Physiographic Divisions).
