Formation of different physical features, plate tectonics and the major physiographic divisions of India.
Introduction to CBSE Class 9 Social Science Geography Chapter "Physical Features of India"
“Physical Features of India” is a chapter that lays out the varied geographical features of India, from the towering Himalayas in the north to the coastal plains in the south. It outlines the six major physical divisions: the Himalayan Mountains, the Northern Plains, the Peninsular Plateau, the Indian Desert, the Coastal Plains, and the Islands.
The chapter emphasizes the processes that led to the formation of these features, such as the tectonic plate movements that created the Himalayas. It also discusses the rich river systems that fertilize the Northern Plains, the ancient igneous and metamorphic rocks that constitute the Peninsular Plateau, the arid Thar Desert, and the lush greenery of India’s coastal regions and islands.
Students learn about the ecological significance of each region, the climatic conditions that prevail, and how these physical features influence the culture, agriculture, and economy of the country. The chapter also provides insight into the conservation efforts required to maintain the delicate balance of these diverse ecosystems.

Questions and Answers for CBSE Class 9 Social Science Geography Chapter "Physical Features of India"
- Q1: What are the major physical divisions of India?
ANS: The major physical divisions of India are the Himalayan Mountains, the Northern Plains, the Peninsular Plateau, the Indian Desert, the Coastal Plains, and the Islands. - Q2: How were the Himalayas formed?
ANS: The Himalayas were formed by the tectonic collision of the Indian plate with the Eurasian plate, which led to the upliftment of the Himalayan ranges. - Q3: What is the significance of the Northern Plains to India?
ANS: The Northern Plains are significant due to their fertile alluvial soil, which supports intensive agriculture and is the densely populated region of India, contributing significantly to the country’s food security. - Q4: Describe the Indian Desert and its location.
ANS: The Indian Desert, also known as the Thar Desert, is located in the northwestern part of the Indian subcontinent, and is characterized by arid conditions, sandy terrain, and sparse vegetation. - Q5: How do physical features affect the climate of India?
ANS: Physical features like the Himalayas act as a barrier to cold winds, protecting India from severe cold, while the coastal location influences the monsoon winds, affecting the rainfall patterns in the country. - Q6: Why is the Peninsular Plateau known for its mineral wealth?
ANS: The Peninsular Plateau is known for its mineral wealth because it is made up of ancient crystalline igneous and metamorphic rocks, which contain rich deposits of various minerals. - Q7: What types of soils are found in the Coastal Plains of India?
ANS: The Coastal Plains of India generally have sandy soil in the west and alluvial and loamy soil in the east, which support diverse agricultural practices. - Q8: Why is biodiversity conservation important in the Islands of India?
ANS: Biodiversity conservation is important in the Islands of India to protect the unique ecosystems that host a wide range of flora and fauna, some of which are endemic to these regions. - Q9: How do the physical features of India influence its economy?
ANS: India’s physical features influence its economy by determining agricultural potential, mineral resources, tourism opportunities, and influencing trade through its extensive coastline. - Q10: What are some challenges in conserving India’s physical features?
ANS: Challenges in conserving India’s physical features include rapid industrialization, urbanization, deforestation, pollution, and the increasing pressure of population growth on natural resources.
