Very Short Question and Answers - Introduction

The term drainage describes the river system of an area.

The area drained by a single river system is called a drainage basin.

A water divide is an elevated area, such as a mountain or upland, that separates two drainage basins.

The drainage systems of India are mainly controlled by the broad relief features of the subcontinent.

The two major groups of rivers in India are the Himalayan rivers and the Peninsular rivers.

Most Himalayan rivers are perennial, meaning they have water throughout the year.

The Indus and the Brahmaputra originate from the north of the mountain ranges.

In the middle and lower courses, Himalayan rivers form meanders, oxbow lakes, and various depositional features in their floodplains.

Many peninsular rivers are seasonal, as their flow is dependent on rainfall.

The Peninsular rivers have shorter and shallower courses compared to the Himalayan rivers.

During the dry season, even large rivers in the peninsular region have reduced flow of water in their channels.

Most of the rivers of peninsular India originate in the Western Ghats and flow towards the Bay of Bengal.

Himalayan rivers perform intensive erosional activity in their upper courses and carry huge loads of silt and sand.

Some examples of large rivers in India include the Ganges, Yamuna, Indus, and Brahmaputra.

Rivers in their lower courses often develop well-developed deltas.

The two major Himalayan rivers mentioned are the Indus and the Brahmaputra.

During the monsoon season, Peninsular rivers experience increased flow due to rainfall.

An elevated area, or water divide, separates two drainage basins.

The Himalayas serve as a source of perennial rivers, affecting their flow and geophysical characteristics.

Himalayan rivers have long courses because they originate in the mountains and flow down to the sea, cutting through the topography.
