Explanation: The River Chambal, a tributary of the Yamuna, is well-known for its unique badland topography. Badlands are characterized by deeply dissected and eroded landscapes, often with steep slopes and ravines. This type of topography is a result of intense erosion by the river and its tributaries, which have carved out the landscape over time. The Chambal River flows through the states of Madhya Pradesh, Rajasthan, and Uttar Pradesh, and its basin is a prime example of badland topography.
The River Ghaghara, on the other hand, is a major tributary of the Ganga. It originates in the Himalayas and flows through Nepal before entering India. The Ghaghara is one of the largest tributaries of the Ganga and plays a significant role in the hydrology of the region. However, the statement that it enters the Ganga plain in Champaran district of Bihar is incorrect. The Ghaghara actually enters the Ganga plain in the district of Pilibhit in Uttar Pradesh. This misconception might arise from a lack of detailed knowledge about the river's course and the geography of the region.
Understanding the geography of Indian rivers and their associated topography is crucial for students preparing for competitive examinations such as the UPSC Civil Services, SSC CGL, State PSC Exams, and Bank PO Exams. It is important to be aware of the specific features and courses of major rivers to avoid common misconceptions and to accurately identify the correct information.
In summary, the River Chambal is indeed famous for its badland topography, making the first statement correct. However, the River Ghaghara does not enter the Ganga plain in Champaran district of Bihar, making the second statement incorrect. Therefore, the correct answer is that only the first statement is correct.
