Explanation / Answer

7. The largest size particle that a stream can carry is (d) Dependent on stream velocity

Explanation : The greater is the velocity of the fluid carrying the sediment particles , the more larger size particles the stream can carry.

8. As the velocity of flow decreases, (d) All of the above

Explanation: (a) option is correct as flow becomes kaminar with decrease in velocity while flow becomes turbulent with increase in flow velocity,

(b) Option is correct as below a certain velocity streams sop eroding and start depositing. As the velocity falls down first the coarser sediments are deposited followed by finder sediments which are suspended sediments

(c) Option is correct as the maximum velocity of flow decreases with decrease in flow

Hence ALL OF THE ABOVE

9.(d) Streams require a high velocity to erode silt.

Explanation : From the graph we see that silt requires a higher velocity than sand to get eroded. The reasin why silt requires higher velocity than sand even though being less in particle size is because due to the small size of the particles there may exist some cohesive foreces aming the small particles.

10.(a) It takes a very large velocity to transport pebbles

Explanation: From the diagram it is clear that Large particles like pebble require hiigh velocity of the fluid so that the particle can be transported,

11. The flat lying area surrounding a river channel is termed the (c)floodplain
