Geography of India: Location and Physiographic Units

Study Notes

Location and Extent

India is located in South Asia, situated between the Himalayas in the north and the Indian Ocean in the south.
It extends from 8°4' North to 37°6' North latitude and 68°7' East to 97°25' East longitude.
India shares land borders with Pakistan, Afghanistan, China, Nepal, Bhutan, Bangladesh, and Myanmar.

Physiographic Divisions

India's diverse topography is divided into several physiographic units:
- The Himalayas: A towering mountain range, including the highest peaks in the world.
- The Northern Plains: A vast fertile plain formed by the alluvial deposits of the Indus, Ganges, and Brahmaputra rivers.
- The Peninsular Plateau: A stable landmass comprising a complex structure of highlands and plateaus.
- The Coastal Plains: Located along the coasts of the Arabian Sea and the Bay of Bengal, characterized by flat terrain and sandy beaches.
- The Islands: Include the Andaman and Nicobar Islands in the Bay of Bengal.

Drainage System

India has a vast network of rivers, many of which originate in the Himalayas.
Major rivers include the Indus, Ganges, Brahmaputra, Godavari, Krishna, Narmada, and Kaveri.
Rivers play a crucial role in irrigation, transportation, and hydroelectric power generation.
The monsoon season significantly impacts river flow patterns.

Climate

India's climate is diverse, influenced by its vast size and complex topography.
A significant portion of the country experiences a tropical monsoon climate.
The climate varies regionally, from the hot and arid deserts of Rajasthan to the sub-tropical highlands of the Himalayas.
The monsoon season is crucial for agriculture, and its variations can cause floods or droughts.

Natural Resources

India possesses a wide range of natural resources, including minerals (iron ore, coal, manganese), forests, and water resources.
Availability and distribution vary across different regions.
The exploitation of these resources impacts the environment and needs careful management.

Biodiversity

India's diverse ecosystems support a rich variety of flora and fauna.
Different habitats like forests, grasslands, and wetlands house a large number of species.
Conservation efforts are crucial due to increasing threats to biodiversity.

Soils

India has various soil types, influencing agricultural productivity.
Alluvial soils are predominant in the northern plains, while black soils are found in the Deccan Plateau, known for their fertility.
Soil erosion and degradation are significant concerns in several regions.

Population Distribution

India has a large and diverse population, concentrated primarily in the northern plains.
Population density varies significantly across different regions.
Urbanization is increasing, leading to changes in population distribution and resource demands.

Important Features

The Thar Desert is a significant arid region.
The Western Ghats are a range of hills running along India's western coast.
The Eastern Ghats are a range of hills running along India's eastern coast.
The Deccan Plateau is a large plateau region.
The Himalayas provide a significant water source.

Political Divisions

India is divided into states and union territories.
Political boundaries influence development and resource allocation.
Interactions and relationships between states and regions are important aspects of geography.
