Indian Geography: Physical Features and Climate

The Bhabar is a narrow belt of land at the foot of the Shivalik hills in the Himalayan piedmont zone. It is composed of pebbles and gravel brought down by rivers, making it highly porous so that small streams often disappear underground.

From south to north, the sequence of these ranges is: Dhauladhar (Lesser Himalayas), Zanskar (Trans-Himalayas), Ladakh (Trans-Himalayas), and Karakoram (the northernmost range).

The Himalayas are formed by the ongoing collision between the Indian Plate and the Eurasian Plate. This plate tectonic activity causes significant seismic stress, leading to frequent earthquakes along the mountain range and its foothills.

The Kathiawar Peninsula in Gujarat is characterized by features like raised beaches and inland sea cliffs, which indicate that the land has risen relative to the sea level, making it an example of an emerged shoreline.

In the Eastern Himalayas, the altitudinal zone between 1000 and 2000 meters is typically occupied by sub-tropical broad-leaved forests. Below this zone are tropical evergreen forests, and above it are temperate forests.

Harlan Barrows is known for the concept of Human Ecology. Griffith Taylor introduced Neo-determinism (Stop-and-Go determinism). Carl Ritter was a major figure in Environmental Determinism, and Eduard Ullman is associated with spatial interaction and cultural geography.

The National Waterway 1 (NW-1) is the longest navigable stretch of the Ganga river system, running from Allahabad (Prayagraj) in Uttar Pradesh to Haldia in West Bengal.

Jawaharlal Nehru Port, also known as Nhava Sheva, was commissioned in 1989 as India's first highly automated and technologically advanced port. It was designed to handle large container traffic and relieve the congestion at the Mumbai Port.

The Nilgiri Hills, located at the junction of Tamil Nadu, Karnataka, and Kerala, serve as the meeting point for the Eastern Ghats and the Western Ghats. This mountainous region is a significant biodiversity hotspot in South India.

Bhima is a major tributary of the Krishna river. Tista is a tributary of the Brahmaputra, Indravati flows into the Godavari, and the Chambal is a primary tributary of the Yamuna.

Western disturbances are extra-tropical storms originating in the Mediterranean region that bring winter rainfall to the northwestern parts of India. This moisture is vital for the growth of Rabi crops like wheat.

Gahirmatha beach in Odisha is famous as the world's largest nesting rookery for Olive Ridley sea turtles. Thousands of these endangered turtles migrate to this coast annually for mass nesting, known as arribada. Sagarmatha refers to Mount Everest in Nepal.

Extensive gully erosion is the defining characteristic of the Chambal River basin, which creates 'badlands'. The Ganga is characterized by its braided nature, sandbars, and massive sediment load, but not by extensive gully erosion.

The Rigvedic names for the rivers of the Punjab region are: Asikni (Chenab), Parushni (Ravi), Sutudri (Sutlej), and Vitasta (Jhelum).

Latur experienced a massive earthquake rather than riverine flooding. Nashri, known for the Chenani-Nashri tunnel area, frequently faces landslides, and Kandla is a major port in Gujarat frequently affected by cyclones. Therefore, pairs 2 and 3 are correctly matched.

The Gondwana system contains nearly all of India's coal. Bhanger refers to older, higher alluvial plains. The Indravati river flows through the Dandakaranya region, and Uttar Pradesh contains the longest stretch of National Waterway 1.

The 'Rally for the Valley' was a protest movement organized by the Narmada Bachao Andolan. It aimed to highlight the social and environmental costs of large dams, specifically focusing on the inadequate resettlement of displaced tribal and rural populations.

Among all Indian states, Gujarat has the longest coastline. However, among the options provided, Andhra Pradesh has the longest coastline (approx. 974 km), followed by Tamil Nadu.

Shifting cultivation (Jhum) involves clearing forest patches for farming and then abandoning them. Due to population pressure, the fallow periods have shortened, preventing forest regeneration and leading to barren hills in Nagaland.

Udaipur is known as the 'City of Lakes'. Kakinada is a major port on the coast of Andhra Pradesh. Faizabad (near Ayodhya) is on the banks of the Saryu river, and Jammu is located in the Shivalik foothills.

Tropical moist deciduous forests in India typically develop in regions that receive an annual rainfall between 100 cm and 200 cm. These forests are found in the wetter parts of the peninsular plateau and along the foothills of the Himalayas. Rainfall ranges define the major forest types of India.

Devaprayag is the sacred confluence where the Alaknanda and Bhagirathi rivers meet. From this point on, the river is officially called the Ganga.

West Bengal has the largest mangrove coverage in India due to the Sundarbans. In ascending order of the given states, Goa has the least, followed by Andhra Pradesh, then Odisha, and finally West Bengal with the most.

The Gulf of Khambhat and the Gulf of Kutch in Gujarat have very high tidal ranges, making them the most suitable locations for generating tidal energy in India.

Namdapha is in Arunachal Pradesh, Periyar is in Kerala, Bandipur is in Karnataka, and Keibul Lamjao is in Manipur. The correct matching sequence is A-2, B-4, C-1, D-3.

James Hutton, the father of modern geology, introduced the concept of uniformitarianism. It posits that geological processes occurring today are the same as those that shaped the Earth in the past.

Among the listed cities, Delhi has the lowest average elevation at approximately 215 meters above mean sea level. Jodhpur (230m), Kota (270m), and Nagpur (~310m) are all situated at higher altitudes.
