Indian Geography MCQs with Answers & AI Explanation

The best soil for cotton in India is Regur soil, also known as black cotton soil. It is rich in lime and clay, expanding when wet and cracking on drying, which helps retain moisture and provides a durable moisture supply for cotton fibers. This soil is common in the Deccan region and supports deep, vigorous cotton growth when irrigation and drainage are managed. Red and Laterite soils are generally poor for cotton due to low moisture retention and nutrient content; Alluvial soil is suitable for many crops but Regur soil is especially favorable for cotton cultivation.

Trans-humance refers to the seasonal movement of people with their livestock between fixed summer (highland) and winter (lowland) pastures. It contrasts with simple pastoralism, which may be more sedentary or nomadic without fixed seasonal routes. In the Himalayan context, herders move to highlands in summer to graze young grasses and descend to lower lands in winter when high pastures are less available. The key idea is the systematic, recurring transfer between two sets of grazing grounds. Nomadism implies continuous movement without fixed seasonal destinations, while ranching is typically large-scale, enclosed cattle farming. Hence, trans-humance best fits the described practice.

The Himalayas were formed due to the collision of the Indian Plate with the Eurasian Plate, a tectonic event that began in the Caenozoic era. This era followed the Mesozoic and is known for significant mountain-building activities in the region. Options A (Palaeozoic) and B (Mesozoic) refer to earlier geologic times when major orogenies did not produce the Himalayas, and D (Azoic) is an invalid era indicating no life. Hence, the correct era for the major folding and uplift of the Himalayas is the Caenozoic (Option C).

Correct option is B. Kakrapar Atomic Power Project is in Gujarat, not Tamil Nadu. Kalpakkam is in Tamil Nadu, not Karnataka. Narora Nuclear Power Station is located in Uttar Pradesh. Therefore, only (iii) is correctly matched. The question tests knowledge of the location of major nuclear power plants and avoids incorrect pairings by state. Understanding the actual state locations helps avoid confusion with similarly named places.

The Tungabhadra river is part of the Krishna river basin. It joins the Krishna, whose waters ultimately reach the Bay of Bengal, not the Arabian Sea. In contrast, Sabarmati, Mandovi, and Narmada drain into the Arabian Sea. Thus, Tungabhadra is the one that does not flow into the Arabian Sea.

The Satpura Range is a central Indian hill range. Its highest peak is Dhupgarh, located near Pachmarhi in Madhya Pradesh, with an elevation around 1,359 meters. Gurushikhar is in the Aravalli Range, Pachmarhi is a town in the Satpura region, and Mahendragiri is a peak in the southern peninsula region. Thus, Dhupgarh (Option B) is the correct highest point in the Satpura Range.

The Tropic of Cancer is the northernmost latitude where the sun can be directly overhead, located at about 23.5°N. In India, this circle of latitude passes through several states from west to east. Among the given options, the states that lie along this line are Rajasthan, Jharkhand, West Bengal, and Mizoram. This helps identify the correct group when tracing the path of the Tropic of Cancer across the map. Other options include states that lie either north of or south of this latitude or lie off the Tropic’s path, so they are not correct.
