  1. Where the delta of river begins

  2. Where two or more rivers meet

  3. Land between two separate river systems

  4. Land between two tributaries of a river

Show answer
Correct Option: D
Explanation:

Land between two tributaries of a river means 'Doab'. The place where two small streams join together and results in the formation of a big river is called a DOAB. The small streams might be the tributaries of a river also.


Doab. Doab is a term used in South Asia for the "tongue," or tract of land lying between two converging, or confluent, rivers. McGregor defines it as "(Persian do-āb: a region lying between and reaching to the confluence of two rivers.

Factors affecting work of river are ____________.

geography rivers rivers and their work exogenic forces exogenic processes part-1

  1. Velocity of water

  2. Volume of water

  3. Load

  4. All of these

Show answer
Correct Option: D
Explanation:

Factors affecting work of river are Velocity of water, Volume of water and Load.
The flow velocity, or speed of flow, can influence the shape and rate of erosion of a river system. The cross-sectional shape of a river dictates how much friction will impact the flow of water within a river. Finally, the sediment load, or the amount of rocks and soil in the river, impacts its flow velocity and shape.

A river enters the sea or disappears before joining the sea is called its _________.

  1. mouth

  2. source

  3. course

  4. none of these

Show answer
Correct Option: A
Explanation:

The last past of the river when it reaches the end of its journey, it is called an old river or the old stage. The end of the river is called the mouth. At the mouth, there is often a river delta, a large, silty area where the river splits into many different slow-flowing channels that have muddy banks. At this stage deposition is the only work of the river.

Erosion, transportation and deposition are factors of _________.

geography rivers rivers and their work exogenic forces exogenic processes part-1

  1. River

  2. Soil

  3. Both a and b

  4. None of these

Show answer
Correct Option: C
Explanation:

Erosion is the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it away to another location. The particulate breakdown of rock or soil into clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by its dissolving into a solvent, followed by the flow away of that solution. Eroded sediment or solutes may be transported just a few millimeters, or for thousands of kilometers.

Natural rates of erosion are controlled by the action of geomorphic drivers, such as rainfall or bedrock wear in rivers or coastal erosion by the sea and waves or glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows.
