Explanation: The Purvanchal hills are a significant geographical feature in the northeastern part of India. They are a series of hills that form part of the eastern Himalayan range and extend through several northeastern states. The term "Purvanchal" translates to "Eastern Range" in Sanskrit, reflecting their location in the eastern part of the country.
The Purvanchal hills are characterized by their rugged terrain, dense forests, and rich biodiversity. They are home to numerous tribal communities and are known for their cultural and ecological significance. The hills are also important for their role in the region's hydrology, as they are the source of several important rivers.
The states that are part of the Purvanchal hills include Assam, Meghalaya, and Manipur. Assam is a large state located in the northeastern region of India, known for its tea plantations and wildlife reserves. Meghalaya, which means "abode of clouds," is known for its heavy rainfall and lush green landscapes. Manipur, located in the northeastern region, is known for its rich cultural heritage and scenic beauty.
It is important to note that while these states are part of the Purvanchal hills, the region also includes parts of other northeastern states such as Arunachal Pradesh, Nagaland, and Tripura. However, the question specifically asks for the states that are included in the Purvanchal hills, and the correct answer is Assam, Meghalaya, and Manipur.
Understanding the geographical features of India, such as the Purvanchal hills, is crucial for comprehending the country's physiography and the cultural and ecological diversity of its regions. This knowledge is particularly important for students preparing for competitive examinations that test their understanding of Indian geography and physiography.
