The Shiwaliks Range in the Himalayas is composed of unconsolidated sediments brought down by rivers. Let's understand this in detail:
Shiwaliks Range:
- The Shiwaliks Range is the southernmost range of the Himalayas, also known as the Outer Himalayas.
- It stretches from the Indus River in Pakistan to the Brahmaputra River in India.
- The range is composed of unconsolidated sediments brought down by various rivers such as the Sutlej, Ganga, and Yamuna.
- These sediments consist of sand, gravel, and boulders, which were deposited over millions of years as the rivers flowed through the region.
- The sediments are not consolidated, which means they are not cemented together, making the range prone to erosion and landslides.
Ladakh Range:
- The Ladakh Range is located in the northernmost part of the Himalayas and is composed of hard rocks such as granite, gneiss, and schist.
- The range is not composed of unconsolidated sediments brought down by rivers.
Karakoram Range:
- The Karakoram Range is located to the northwest of the Himalayas and is composed of rocks that were formed by the collision of the Indian and Eurasian plates.
- The range is not composed of unconsolidated sediments brought down by rivers.
Therefore, the correct answer is option 'A' - The Shiwaliks Range in the Himalayas is composed of unconsolidated sediments brought down by rivers.
