Test: The Physical Divisions of India - Class 4 MCQ

Wheat is one of the main crops cultivated in the Satluj Basin, along with rice, pulses, cotton, and oilseeds. The fertile alluvial soil of this basin, enriched by river systems, supports extensive agricultural activities.

The Himalayas play a vital role in the Indian monsoon system by acting as a barrier that traps moisture-laden winds, facilitating rainfall across much of India. This phenomenon is essential for agriculture and the ecosystem in the region.

The Eastern Coastal Plains are broader than the Western Coastal Plains. This region is known for its fertile soil which is conducive to agriculture, making it a significant area for farming and fishing activities.

The Sundarbans, formed at the confluence of the Brahmaputra and Ganga rivers before they drain into the Bay of Bengal, is the largest delta in the world. It is known for its rich biodiversity, including the famous Bengal tiger.

The Northern Plains are often referred to as the "Food bowl of India" due to their fertile soil and abundant water supply from rivers, making agriculture, particularly the cultivation of crops like rice and wheat, the primary activity in this region.

The Himalayas, translating to "home of snow" in Sanskrit, are renowned for their towering heights and perennial snow cover, making them a critical water source for many rivers in India.

A perennial river has a continuous flow of water throughout the year, primarily sourced from melted glaciers and rainfall. This characteristic is vital for supporting ecosystems and human activities in the regions they flow through.

The Great Indian Desert, also known as the Thar Desert, is characterized by sand dunes that shift shape and size due to strong winds. These dunes create a unique landscape typical of arid environments, contrasting sharply with other geographical features in India.

The glaciers in the Himalayas are critical for northern Indian rivers as they melt and contribute water throughout the year, ensuring a continuous supply that supports agriculture and drinking water needs.

Non-perennial rivers, which primarily receive water from rainfall and can dry up in summer, are predominantly found in peninsular India. Rivers like the Mahanadi, Godavari, and Krishna are examples of this category.

The Shiwalik range is known for its large flat valleys, referred to as Duns, such as Dehra Dun and Patli Dun. It is the lowest range among the Himalayas, with elevations between 900 and 1100 meters, and is rich in forests and wildlife.

The Kashmir Valley is located within the Himachal range of the Himalayas. Known for its stunning landscapes, it is also a significant tourist destination due to its natural beauty and cultural heritage.

The Andaman and Nicobar Islands house the only active volcano in India, located on Barren Island. This geographical feature contributes to the volcanic landscape and biodiversity of the islands, making them unique.

The Peninsular Plateau lies directly to the south of the Northern Plains. This region is characterized by its triangular shape and rocky terrain, consisting of several smaller plateaus, including the Malwa, Chota Nagpur, and Deccan Plateaus.

The Great Indian Desert has a hot and dry climate, characterized by extreme temperature fluctuations between day and night, with scarce rainfall. This arid environment supports limited vegetation, mainly adapted to dry conditions.

The Peninsular Plateau is abundant in minerals like iron, coal, manganese, and bauxite, which are crucial for the country's industry. Its rugged terrain and diverse geology make it a key resource area.

The Himadri, also known as the Greater Himalayas, is the highest range in the Himalayas, featuring peaks that exceed 6000 meters, including Mount Everest, which stands at 8848 meters. This range is characterized by its perpetual snow cover and significant glaciers like Gangotri and Siachen that contribute to major rivers.

The Ganga is a perennial river, meaning it has water throughout the year, sourced from glaciers and rainfall. This characteristic makes it crucial for agriculture and water supply in northern India, unlike non-perennial rivers that can dry up in summer.

The Brahmaputra does not belong to the Ganga Basin; it forms its own basin and flows through the northeastern part of India. The Ganga Basin includes rivers such as the Yamuna and its tributaries, which are vital for agriculture in the region.

The Western Coastal Plains are renowned for their fishing industry, where local communities engage in fishing activities and export seafood. The proximity to the Arabian Sea facilitates this important economic activity.
