Question 7

What is the source of a river

Answer 7

The start of the river

Question 8

What are the tributaries

Answer 8

Small streams or rivers coming off main river

Question 9

What is the mouth of a river

Answer 9

The end

Question 10

What is the confluence?

Answer 10

The point where a tributary joins the main channel

Question 11

What does the upper course of the river surrounding look like

Answer 11

High and steep

Question 12

What way does it erode in the upper course

Answer 12

Vertically

Question 13

Is the river channel deep and wide in the upper course

Answer 13

No it is shallow and deep in the upper course as there isn’t much water

Question 14

What are the landforms in the upper course

Answer 14

Interlocking spurs, waterfalls, gorges and u shaped valleys

Question 15

What is river velocity

Answer 15

The speed of the water

Question 16

What is river discharge

Answer 16

The amount of water in the river channel

Question 17

What is the gradient of the landscape in the middle course

Answer 17

Much less steep

Question 18

How does the river erode in the middle course

Answer 18

Vertically making the river channel deeper

Question 19

Does the river begin to widen in the middle course

Answer 19

Yes by lateral erosion as the river discharge is higher

Question 20

Does the velocity increase in the middle course

Answer 20

As less water is making contact with r the bed and banks the water velocity increases

Question 21

What landforms are made at the middle course

Answer 21

Meanders and oxbow lakes

Question 22

What is the gradient of land in the lower course

Answer 22

Very low / flat

Question 23

Is the channel wide or narrow at the lower course

Answer 23

The channel is widest and deepest in the lower course as discharge and velocity is at its highest

Question 24

What landforms are at the lower course

Answer 24

Meanders, oxbow lakes, flood plains, levees and u shaped valleys

Question 25

What is a cross profile

Answer 25

An imaginary slice across a river channel and it’s valley at a particular point

Question 26

What are the 4 types of erosion

Answer 26

Hydraulic action, attrition, abrasion and solution

Question 27

what are the 4 types of transportation

Answer 27

Suspension(fine sediment), traction(large sediment), saltation(smaller sediment),
solution(smaller sediment)

Question 28

What is a floodplain

Answer 28

Wide flat area of marshy land either side of a river

Question 29

What is a levee

Answer 29

raised banks have n either side of the river in the lower course

Question 30

What is lag time

Answer 30

Time between peak rainfall and peak discharge

Question 31

What is rising limb

Answer 31

The amount of water in river increasing

Question 32

What is falling limb

Answer 32

Yeh amount of water in the river decreasing

Question 33

What shows there is more risk of flooding

Answer 33

A shorter lag time and steeper rising limb
