Ans : (i)The person will prefer to travel from the western coastal plains because the Lakshd'.veep islands are situated in Arabian Sea which distance is lowest from this coast. Therefore, it will take the least time to reach the Lakshadweep.


(ii) The cold desert in India is located in the north eastern part of the Kashmir Himalayas, which lies between the Greater Himalayas and the Karakoram ranges.


(iii) The western coastal plains are narrow and have steep slope. The rivers flow rapidly in one part and hence they don't form any deltas. Therefore, the western coastal plain is devoid of any delta. 

Ans : (i)





(ii) The river valley plains are formed by the alluvial deposits brought by the rivers. The important geomorphological features found in the river valley plains are:
Bhabar is a narrow belt ranging beüeen 8-10 km parallel to the Shüualik foothills at the break-up of the slope.
Terai: South of the Bhabar is the Terai belt, with an approximate width of 10-20 km where most of the streams and rivers re-emerge without having any properly demarcated channel, thereby, creating marshy and swampy conditions known as the Tarai.This has a luxurious growth of natural vegetation and houses a varied wildlife.

Bhangar: It is composed of old alluvium. These areas are less prone to flooding and less fertile as well.
Khadar: It is composed of new alluvial deposits. These areas are prone to flooding and are very fertile.
Delta: A river delta is a landform that occurs at the mouth of a river near where the river flows into the ocean. For example, the famous Sunderbans delta.



(iii) Badrinath is situated along Ganga river. The Sunderban delta is on the mouth of Ganga and Brahmaputra in Bay of Bengal. If we are moving from Badrinath to Sunderbans delta along the course of the river Ganga, we will come across various of geomorphological features. As we start moving we will come across gorges, V-shaped valleys, rapids, waterfalls, etc. 
We will also see places where tributaries meet main river Ganga After sometime, we will enter into northern plains. We will see various erosional and depositional landforms such as sand bars, meanders, oxbow lakes and braided channels. At last, we will reach our destination, swampy and marshy area known as Sunderbans delta
formed by the Ganga and Brahmaputra river.
