Explanation: Purvanchal is a geographical term that refers to a region in eastern India, comprising a series of hills and plateaus. This region is distinct from the major mountain ranges of India, such as the Himalayas and the Aravalli range, and is not associated with the Indian Desert.
The Purvanchal region includes several important hill ranges and plateaus:
1. **Patki Hills**: These hills are located in the northeastern part of India, primarily in the state of Assam. They form part of the eastern Himalayan range and are characterized by their dense forests and rich biodiversity.
2. **Naga Hills**: The Naga hills are located in the northeastern state of Nagaland. They are part of the Patkai range and are known for their rugged terrain and diverse flora and fauna.
3. **Manipur Hills**: These hills are located in the state of Manipur and form part of the eastern Himalayan range. They are known for their scenic beauty and cultural significance.
4. **Mizo Hills**: The Mizo hills are located in the state of Mizoram and are part of the eastern Himalayan range. They are characterized by their dense forests and are home to various indigenous communities.
The term "Purvanchal" is derived from the Sanskrit word "Purva," which means "east." This term accurately reflects the eastern location of these hills and plateaus. The Purvanchal region is distinct from the Himalayas, which are located in the northern part of India, and the Aravalli range, which is located in the western part of the country. The Indian Desert, also known as the Thar Desert, is located in the western part of India and is not associated with the hills and plateaus of the Purvanchal region.
Understanding the geographical distribution of these hills and plateaus is crucial for comprehending the physiography of eastern India. The Purvanchal region plays a significant role in the ecological and cultural landscape of the northeastern states of India.
