Additional Practice Questions
Explain the role of plate tectonics in shaping India's physical environment.
mediumAnswer: Plate tectonics have played a crucial role in shaping India's physical environment, as the Indian Plate's movement led to the formation of the Himalayas and other mountain ranges. The northward movement of this plate continues to affect the region's geology and physiography.
Describe the main differences between the Eastern and Western Ghats.
mediumAnswer: The Western Ghats are higher and more continuous than the Eastern Ghats, with numerous peaks like Anaimudi. The Eastern Ghats are eroded by major rivers and are less continuous.
What are the geomorphological processes active in the Indian subcontinent?
mediumAnswer: Geomorphological processes in India include erosion, sediment deposition, and tectonic activities, which result in various landforms like the Himalayas, river valleys, and deltas.
List and describe the distinctive features of the Indian Desert.
mediumAnswer: The Indian Desert, or Thar Desert, features longitudinal dunes, barchans, and extreme arid conditions with low vegetation due to minimal rainfall.
