Explanations:The Hazaribagh and Ranchi plateaus are two significant geographical features located in the state of Jharkhand, India. These plateaus are part of the larger Chota Nagpur Plateau, which is a hilly region in eastern India. The Chota Nagpur Plateau is known for its rich mineral resources and diverse topography.
The Hazaribagh plateau is located in the northern part of Jharkhand, while the Ranchi plateau is situated in the central part of the state. These plateaus are separated by the Damodar River, which is a major tributary of the Hugli River. The Damodar River is approximately 541 kilometers long and flows through the states of Jharkhand and West Bengal. It is known for its historical and ecological significance, as well as its role in the industrial development of the region.
The Damodar River is an important geographical feature that not only separates the Hazaribagh and Ranchi plateaus but also plays a crucial role in the hydrology and agriculture of the region. The river is fed by numerous tributaries and is known for its seasonal flooding, which has been managed through various dam and reservoir projects.
Understanding the geographical layout of Jharkhand, including the locations of its major plateaus and rivers, is essential for comprehending the region's topography and natural resources. The Damodar River, in particular, is a key feature that helps to define the landscape and the ecological and economic activities of the area.
It is important to note that the other options provided in the question are not relevant to the geographical context of Jharkhand. The Narmada River, for example, is located in central India and does not flow through Jharkhand. Similarly, the Mahanadi River is located in eastern India, primarily in Odisha, and does not separate the Hazaribagh and Ranchi plateaus. The option "But" is not a river name and is likely included as a distractor to test the student's knowledge of the region's geography.
In summary, the Damodar River is the correct answer as it is the river that separates the Hazaribagh and Ranchi plateaus in Jharkhand. Understanding the geographical features and river systems of a region is crucial for comprehending its topography and natural resources.
