What is Geomorphology?
Geomorphology is the scientific study of the origin, evolution, form and distribution of landforms. It examines the processes that shape the surface of the earth, such as erosion, deposition, weathering, tectonics, volcanism and glaciation. Geomorphology also explores the interactions between humans and the environment, such as land use, natural hazards and climate change.
Why is Chota Nagpur Plateau Important?
The Chota Nagpur Plateau is one of the oldest and most diverse geological regions in India. It has been formed by continental uplift from forces acting deep inside the earth. It is part of the Deccan Plateau, which broke free from the southern continent during the Cretaceous period and collided with the Eurasian continent. The plateau has a rich history and culture, as it was home to various ancient kingdoms and tribes, such as the Nagavanshis, who gave it its name.
The plateau is also a storehouse of valuable rocks and minerals of Precambrian origin. It has deposits of coal, iron ore, manganese, bauxite, copper, mica and uranium. It is also known for its forests, wildlife and waterfalls. The plateau has several protected areas, such as Betla National Park, Hazaribagh Wildlife Sanctuary and Dalma Wildlife Sanctuary.

What are the Major Geomorphological Features of Chota Nagpur Plateau?
The Chota Nagpur Plateau can be divided into three steps or regions, based on their elevation and relief. These are:
The highest step is in the western part of the plateau, where the average elevation is 910 to 1,070 metres (3,000 to 3,500 ft) above sea level. This region is also known as the Pat region, and it consists of flat-topped hills or pats that are separated by deep valleys. The highest point of the plateau, Parasnath Hill (1,164 metres or 3,819 ft), is located in this region.
The middle step is in the central part of the plateau, where the average elevation is 610 to 910 metres (2,000 to 3,000 ft) above sea level. This region includes the Ranchi Plateau, the Hazaribagh Plateau and the Koderma Plateau. These plateaus are characterized by undulating terrain and moderate slopes. The Ranchi Plateau is the largest and most populous of these plateaus, and it is drained by the Subarnarekha River and its tributaries.
The lowest step is in the eastern and southern part of the plateau, where the average elevation is 300 to 610 metres (980 to 2,000 ft) above sea level. This region comprises the Damodar trough, the Palamu region and the Manbhum-Singhbhum region. The Damodar trough is a narrow valley that runs along the Damodar River and its tributaries. The Palamu region is a hilly area that lies to the west of the Damodar trough. The Manbhum-Singhbhum region is a rolling plain that lies to the east of the Damodar trough and extends into Odisha. This region is rich in iron ore and other minerals.
What are the Geomorphic Processes that Shaped Chota Nagpur Plateau?
The geomorphic processes that shaped Chota Nagpur Plateau can be classified into two categories: endogenic and exogenic. Endogenic processes are those that originate from within the earth, such as tectonics, volcanism and magmatism. Exogenic processes are those that originate from outside the earth, such as weathering, erosion, deposition and glaciation.
The endogenic processes that influenced Chota Nagpur Plateau include:
The formation of the Deccan Plateau by continental rifting and volcanic eruptions during the Cretaceous period.
The collision of the Indian Plate with the Eurasian Plate during the Tertiary period, which caused uplift and folding of the plateau.
The intrusion of granites and other igneous rocks into the older sedimentary rocks of the plateau during various periods.
The exogenic processes that affected Chota Nagpur Plateau include:
The weathering and erosion of the plateau by various agents such as wind, water and ice over millions of years.
The deposition of sediments by rivers and streams in valleys and basins.
The glaciation of parts of the plateau during the Pleistocene epoch, which left behind moraines and other glacial features.
What are the Geomorphological Significance and Applications of Chota Nagpur Plateau?
The geomorphological significance and applications of Chota Nagpur Plateau are manifold. Some of them are:
The plateau is a natural laboratory for studying the evolution and diversity of landforms and processes in India. It provides insights into the geological history and tectonic movements of the Indian subcontinent.
The plateau is a hotspot of biodiversity and endemism, as it harbors a variety of flora and fauna that are adapted to the different climatic and ecological zones of the plateau. It also hosts several endemic and endangered species, such as the pygmy hog, the Malabar giant squirrel and the sal tree.
The plateau is a source of livelihood and sustenance for millions of people, especially the tribal communities that inhabit the region. The plateau offers a range of natural resources, such as forests, water, minerals and soil, that support agriculture, forestry, mining and tourism.
The plateau is a site of cultural and historical significance, as it reflects the rich and diverse heritage and traditions of the people who have lived in the region for centuries. The plateau has witnessed several historical events and movements, such as the Santhal rebellion, the Kol uprising and the Jharkhand movement.
What are the Geomorphological Challenges and Threats Facing Chota Nagpur Plateau?
The geomorphological challenges and threats facing Chota Nagpur Plateau are numerous. Some of them are:
The degradation and fragmentation of the plateau's natural environment due to human activities, such as deforestation, mining, urbanization and industrialization. These activities have resulted in loss of biodiversity, soil erosion, water pollution, land subsidence and climate change.
The vulnerability and marginalization of the plateau's population due to poverty, illiteracy, malnutrition and lack of basic amenities. These factors have hampered the development and empowerment of the people, especially the tribal communities that depend on the plateau's resources.
The conflicts and disputes over the plateau's resources and identity among various stakeholders, such as the state governments, the central government, the private sector and the civil society. These conflicts have led to violence, displacement and human rights violations.
What are the Geomorphological Opportunities and Solutions for Chota Nagpur Plateau?
The geomorphological opportunities and solutions for Chota Nagpur Plateau are varied. Some of them are:
The conservation and restoration of the plateau's natural environment through sustainable management practices, such as afforestation, reclamation, watershed development and eco-tourism. These practices can enhance the ecological functions and services of the plateau, such as carbon sequestration, water regulation and biodiversity protection.
The development and empowerment of the plateau's population through participatory and inclusive approaches, such as education, health, livelihood and governance. These approaches can improve the quality of life and well-being of the people, especially the tribal communities that have indigenous knowledge and rights over the plateau's resources.
The cooperation and collaboration among the plateau's stakeholders through dialogue and negotiation, such as regional integration, resource sharing and conflict resolution. These mechanisms can foster peace and harmony among the diverse groups and interests that coexist in the region.
In conclusion, the geomorphology of Chota Nagpur Plateau is a complex and dynamic phenomenon that reflects the interplay of various natural and human factors. The plateau is a geomorphological marvel that offers a wealth of opportunities and challenges for its inhabitants and visitors. The plateau is also a geomorphological heritage that deserves to be preserved and promoted for its scientific, ecological, social and cultural values. d282676c82
