In which part of Himalayas 'Doons' and 'Dwars' are found ?

Question

Accepted Answer

'Doons' and 'Dwars' are found in the Shiwalik Ranges. Here's why:

*   **Shiwalik Ranges:** 'Doons' are longitudinal valleys formed between the Lesser Himalayas (Middle Himalayas) and the Shiwalik Ranges. They are depositional valleys filled with gravel and alluvium. Examples include Dehradun and Kotli Dun. 'Dwars' are similar plains found in the eastern part of the Shiwaliks, particularly in West Bengal and Assam. They are also alluvial plains formed by the depositional activity of rivers. Therefore, the presence of both 'Doons' and 'Dwars' is characteristic of the Shiwalik region.

Now, let's explain why the other options are incorrect:

*   **Trans Himalayas:** The Trans Himalayas are located north of the Greater Himalayas and consist of ranges like the Karakoram, Ladakh, and Zaskar. This region is characterized by high altitudes, cold deserts, and different geological formations. 'Doons' and 'Dwars' are not features typically associated with the Trans Himalayas.

*   **Greater Himalayas:** The Greater Himalayas are the highest and most continuous range of the Himalayas. They are characterized by high peaks, glaciers, and rugged terrain. 'Doons' and 'Dwars' are not found in this region because the steep slopes and glacial activity do not favor the formation of such depositional valleys and plains.

*   **Middle Himalayas:** While the 'Doons' are located *between* the Middle Himalayas and the Shiwaliks, they are *part* of the Shiwalik region. The Middle Himalayas themselves are characterized by hill stations and forests, but not the specific depositional features of 'Doons' and 'Dwars'. The Dwars are not associated with the Middle Himalayas at all.
