Explanation / Answer
Ans.
Part 1 - Matching the location on a bend of a meandering stream to its properties
1.Erosion - outside of meander bend.
2.Deposition - Inside of meander bend.
3.Water moves faster - Outside of meander.
4.Water moves slower - Inside of meander.
5.Deeper - Inside of meander bend.
6.Shallow - Outside of meander bend.
Explanation- A meandering stream migrates laterally by sediment erosion on the outside of the meander, and deposition on the inside (helicoidal flow, deceleration, channel lag, point bar sequence, fining upwards). Adjacent to the channel levee deposits build up, and gradually raise up the river over the floodplain.
Part -2
1.Mineral dissolved in water - called Solution(A).
2.Particles held up by running water - Suspension(B).
3.Particles bounced along a stream - Bed load(C).
Explanation- The suspended load of a flow of fluid, such as a river, its evolved sediment uplifted by the fluid's flow in the process of sediment transportation.Flowing water dissolves materials from the channel contributing to stream's dissolved or, solution load.Whereas Bed load is that which is moved across the bed of the channel. Bed load is transported in two ways, traction, which is a scooting and rolling of particles along the bed. The second is saltation, a bouncing-like movement.
Part -3 How does urbanization cause flooding -
Ans.(A) Faster runoff slower infiltration.
Explanation- urbanisation,increasing flood risk because towns and cities have more impermeable surfaces. deforestation, because removing trees reduces the amount of water intercepted and increases run-off.
