Questions and Solutions

Multiple Choice Questions

1. In which part of Himalayas do we find the Karewa formation?
  1. North-eastern Himalayas
  2. Himachal-Uttarakhand Himalayas
  3. Eastern Himalayas
  4. Kashmir Himalayas
Solution: The Karewa formations are a unique geological feature characterized by thick, unconsolidated sediments. These formations are predominantly found in the **Kashmir Himalayas**. They are significant for their rich deposits of minerals and fossils, and are often associated with glacial and interglacial periods.
2. In which of the following states is Loktak lake situated?
  1. Kerala
  2. Uttarakhand
  3. Manipur
  4. Rajasthan
Solution: Loktak Lake is the largest freshwater lake in North-East India and is situated in the state of **Manipur**. It is famous for its floating islands, known as 'phumdis', which are a unique ecological feature.
3. Which one of the water bodies separates the Andaman from the Nicobar?
  1. Gulf of Mannar
  2. 11° Channel
  3. 10° Channel
  4. Andaman Sea
Solution: The **10° Channel** is the latitudinal channel that geographically separates the Andaman Islands in the north from the Nicobar Islands in the south. This channel is a significant geographical marker in the Bay of Bengal.
4. On which of the following hill range is the 'Dodabeta' peak situated?
  1. Nilgiri hills
  2. Anaimalai hills
  3. Cardamom hills
  4. Nallamala hills
Solution: The 'Dodabeta' peak, which is the highest peak in the Nilgiri hills, is situated on the **Nilgiri hills**. These hills form part of the Western Ghats in Tamil Nadu and are known for their distinctive topography and biodiversity.

Short Answer Questions (about 30 words)

1. If a person is to travel to Lakshadweep, from which coastal plain does he prefer and why?
Solution: A person travelling to Lakshadweep would prefer the **Kerala coastal plain**. This is because the Kerala coast is geographically closer to the Lakshadweep islands, making travel more convenient and accessible compared to other coastal regions of India.
2. Where in India will you find a cold desert? Name some important ranges of this region.
Solution: A cold desert region is found in the **Leh-Ladakh area** of Jammu and Kashmir. This high-altitude desert is characterized by its arid climate due to the rain shadow effect of the Himalayas. Important mountain ranges surrounding this region include the **Zaskar, Ladakh, and Karakoram ranges**.
3. Why is the western coastal plain devoid of any delta?
Solution: The western coastal plain is generally narrow and bordered by the Western Ghats. Rivers originating from these ghats are relatively short and swift, carrying less sediment. Consequently, they do not have sufficient material to form large deltas before reaching the Arabian Sea.

Long Answer Questions (not more than 125 words)

1. Make a comparison of the island groups of the Arabian Sea and the Bay of Bengal.
Solution: The island groups of the Bay of Bengal, primarily the Andaman and Nicobar Islands, consist of about 572 islands divided into the Andaman (north) and Nicobar (south) groups. These are largely elevated portions of submarine mountains, with some volcanic origins. In contrast, the islands of the Arabian Sea, such as Lakshadweep and Minicoy, are located off the Kerala coast and are composed entirely of coral deposits. Lakshadweep comprises approximately 36 islands, with Minicoy being the largest. These islands often feature storm beaches made of unconsolidated materials.
2. What are the important geomorphological features found in the river valley plains?
Solution: River valley plains exhibit several important geomorphological features. One such feature is the **Bhabar**, a narrow, porous belt of pebble-studded rocks found at the foothills of the Himalayas, extending from the Indus to the Tista rivers. Streams emerging from the mountains deposit their coarser materials here, creating this unique landscape. Other features in river plains can include alluvial fans, meanders, ox-bow lakes, and floodplains, formed by the deposition and erosional activities of the rivers over time.

Common mistakes

  • Confusing the location of geographical features like the Karewa formation or Loktak Lake.
  • Incorrectly identifying the channel separating Andaman and Nicobar.
  • Misplacing the 'Dodabeta' peak on the wrong hill range.
  • Failing to provide adequate reasons for geographical phenomena like the absence of deltas.
  • Incomplete comparison of island groups, missing key distinguishing features.

Revision tips

  • Use maps to pinpoint the locations of all mentioned geographical features like Karewa formation, Loktak Lake, and island groups.
  • Create a table to compare the key characteristics of the Andaman & Nicobar Islands and Lakshadweep.
  • Focus on understanding the 'why' behind geographical explanations, such as the formation of deltas or the presence of cold deserts.
  • Practice drawing simple diagrams to illustrate concepts like the Bhabar region.
  • Review the multiple-choice questions to reinforce factual recall of locations and features.
