Geo Pg 103 Flashcards
How were the Himalayan fold mountains formed?
The Tethys Sea floor was compressed, folded, and uplifted to form the Himalayan fold mountains.
What processes led to the formation of the Northern Plains?
The denudation (wearing down) of the Himalayan Range and Peninsular India, along with further deposition of sediments by rivers, led to the formation of the Northern Plains.
What regions together form a well-knit geographical unit in India?
The Northern Mountains, Northern Plains, and Peninsular Plateau form a well-knit geographical unit.
How are the Northern Mountains, Northern Plains, and Peninsular Plateau mutually interdependent?
These regions are interdependent in many respects such as in climate, agriculture, and resources.
How did the Northern Mountains affect historical invasions and the climate of India?
The Northern Mountains acted as a physical barrier that prevented invasions in the past and are responsible for heavy monsoon rainfall over the subcontinent because winds are forced to ascend their slopes.
What is the significance of glaciers in the Northern Mountains?
The melting of glaciers in the Northern Mountains makes the Himalayan rivers perennial (flowing throughout the year).
What are some key resources found in the Northern Mountain region?
The mountain region has rich forest resources and potential for hydroelectric power.
What are the characteristics of the Northern Plains?
The Northern Plains have fertile alluvial soils, an abundant water supply from rivers, and produce foodgrains like rice and wheat.
What crops are commonly grown in the Northern Plains?
The Northern Plains produce foodgrains, and jute and sugar cane are grown here, forming the basis of agro-based industries.
What mineral resources are found in the Peninsular Plateau?
The Peninsular Plateau has rich mineral resources such as coal, iron ore, manganese, limestone, mica, copper, and bauxite.
What crops are grown in the Peninsular Plateau?
The Peninsular Plateau is known for cotton and sugar cane cultivation, along with rain-fed crops such as millets, pulses, and oilseeds.
Why are the Coastal Plains important in India?
The Coastal Plains are rich agricultural regions, home to all major trading ports, large cities, and major tourist attractions, including beaches and islands.
