Question

The Karewas of Kashmir refers to which among the following types of deposits?
A) Aeolian and Glacial
B) Fluvial
C) Lacustrine
D) Volcanic

Answer 1

Hint: Karewa means “elevated table land”. Thick deposits of glacial clay and other materials flooded with moraines are called Karewas. These are loose lacustrine deposits. Lacustrine means “associated with lakes”.

Complete answer:
Let us analyze the given options:
Option A) Landforms shaped by wind are called Aeolian. These processes create a number of different features, through both deposition of sediment and erosion, including sand dunes, loess deposits, ventifact etc. Geologic agents, such as rivers, glaciers, and waves are the main supplier for this aeolian to form. On the other hand, glaciers are the moving body of ice and have the potential to construct an entire landscape. Hence this option is incorrect

Option B) Fluvial Systems sculpt the landscape by depositing the sediments to create the new landforms. Human civilization is totally dependent on this type of landform. These systems are dominated by streams and rivers. Hence this option is incorrect

Option C) The Plain that came into being due to the past existence of a lake and its
accompanying deposits collection is called Lacustrine. Glacial drainage, differential uplift, and inland lake creation and drainage can be the various reasons for the formation of these plains. Hence this option is correct

Option D) The volcanic eruptions release a lot of materials like rocks and gases which results in the volcanic deposits after they cool down. Volcanic deposits contribute to the formation of new landforms, a diverse variety of new rocks and richer soil for farming. Hence this option is incorrect

Therefore the correct answer is option ‘C’.

Note: The Karewa deposits consist of sand, silt, clay, shale, mud, lignite, gravel, and loess sediments. Therefore, it is of great importance for the agricultural and horticultural practice in the valley. The world-famous saffron variety, known locally as Zafron, is grown in these sediments. It also helps grow almonds, walnuts, apples, and orchards.
