Answer: Option A. -> have lesser water volume and carry less run-off silt
Answer: (a)
Most of the Western flowing rivers travel a lesser distance than eastern flowing rivers before getting into the sea. On way to the West coast through hard rocks and over a higher gradient, they couldn’t collect a large amount of Slit and flow with very high speed compared to East flowing rivers. Eastern rivers flow through broken hills and mountain ranges.
So, they are widened and flow with lesser velocity before entering into sea. So, they deposit sediments and silt before entering into the sea and can form a Delta.

Answer: Option D. -> Lateral Corrosion
Answer: (d)
Sideways form of erosion is called lateral erosion. In lateral erosion, the river erodes away at its banks and widens the river channel. Together, vertical and lateral erosion create the distinctive V-shaped valley that is found in rivers in their upper course.
As the river gets closer to the sea, there is more lateral erosion than vertical erosion and the V flattens out into a much wider shape.

Answer: Option A. -> Brahmaputra
Answer: (a)
The Yarlung Tsangpo is a watercourse that originates at Tamlung Tso lake in western Tibet, southeast of Mount Kailash and Lake Mansarovar. It later forms the South Tibet Valley and Yarlung Tsangpo Grand Canyon, before passing through the state of Arunachal Pradesh, India, where it is known as the Dihang.
Downstream from Arunachal Pradesh, the river becomes wider and at this point is called the Brahmaputra River. From Assam (India) the river enters Bangladesh at Ramnabazar.
