Multiple Select

Which part of the meander experience the fastest flow?

• the outside part of the bend

• the inside part of the bend

• at the oxbow lake

• the lower course of the river

Multiple Choice

Which feature is formed by the erosion on the meanders?

• deposition

• river cliffs

• delta

• slip-off slope

Fill in the Blanks

The slip-off slope (the river beach) is a result of continuous ... of the river due to the low velocity.

Multiple Select

At the meander, the sides of the river are undercut by these processes.

• vertical erosion

• lateral erosion

• sideways erosion

• depositional

Fill in the Blanks

On a flat land, the river begins to flow in bends called meanders. The development of these bends are dominated by the ... erosion which wears away the sides of the valley, making it wider.

Fill in the Blanks

The fastest flow and the most energy at the river meanders are directed towards the outside of bends, forming

Fill in the Blanks

On the inside of the river bends, the water flow is slowed down by friction in shallower water and deposits material there to form

Multiple Choice

Which of the following has created flood plains?

• overflowing and flooding by the river

• lateral and vertical erosion

• movement of the plate tectonics

• fast-flowing water over hard rocks

Multiple Choice

What is the cause of deposition of fine materials at the river mouth?

• the reduced speed of the river due to its high velocity

• the reduced speed of the river because of the lateral erosion

• the slowing down velocity of the river when a tributary joins the main river channel

• the speed of the river is slowing down when meeting the sea

Multiple Choice

The followings are the things that make huge areas of deposition at the delta of MIssissippi, Nile and Ganges rivers, except ....

• high rate of deposition by the river

• low velocity of the river at the river mouth

• strong current of the sea at the point where fresh and saltwater meet

• slow current of the sea at the river mouth

Fill in the Blanks

In their lower course, the rivers split into numerous channels due to the deposition of silt. These are called the

One of the main hazards which leads to losing property is

Open Ended

What are three opportunities offered by the river?

Draw

The river runs to northwest direction. Mark the part where it has the fastest velocity.
