Question 1

where are the uk’s upland

Answer 1

Most of our upland habitats are found in Scotland, Wales and Northern England

Question 2

where are the uk’s lowland

Answer 2

Lowland areas are mostly found in the south and east of the UK. Lowland areas are close to sea level and lie below around 200m. An example is the Fens in East Anglia.

Question 8

tyne river course

Answer 8

Primary source is the South Tyne
which is located in Alston Moor, Cumbria, England
the mouth of river is inTynemouth
which is located in South Shields

Question 9

drainage basin

Answer 9

is the area of land drained by the river and its tributaries

Question 10

source

Answer 10

the start of a river

Question 11

watershed

Answer 11

the edge of a river basin

Question 12

mouth

Answer 12

the end of a river usually where a river joins the sea

Question 13

tributary

Answer 13

a small steam or river that joins the larger one

Question 14

long profile

Answer 14

shows how river gradient changes as the river moves from upper to lower course

Question 15

cross profile

Answer 15

shows the valley shape changes as the river moves from upper to lower course

Question 16

what can be a source

Answer 16

a spring, lake or puddle where rain is collected

Question 17

what happens to a river

Answer 17

the river gets wider from source to mouth and carries more water

Question 18

waterfall

Answer 18

a place where the river flows over a steep side of a valley

Question 19

fluvial processes

Answer 19

a river carries water from land to the sea . a journey that a river makes is called a long profile. fluvial processes such as erosion, transportation and deposition occur. these processes help to shape the valley.

Question 20

erosion

Answer 20

is the wearing away of rocks by natural processes of the river. this can be vertically which makes the river deep or lateral which makes it wide

Question 21

solution

Answer 21

the river carried bits of rocks e.g limestone which dissolves in the river until you cannot see them

Question 22

abrasion

Answer 22

rocks carried along by the river scrape along the river bed and banks like sand paper

Question 23

attrition

Answer 23

rocks smash together and break into smaller rocks

Question 24

hydraulic action

Answer 24

the river water moves fast past the riversides which forces air to be trapped in the soils which weakens the river banks

Question 25

traction

Answer 25

large particles like boulders are pushed along the river bed by the force of water

Question 26

suspension

Answer 26

small particles like clay & silt are carried along by the water

Question 27

solution

Answer 27

soluble material dissolves in the water are carried along

Question 28

saltations

Answer 28

pebble-sized particles are bounced along the river bed by the force of the water

Question 29

depositions

Answer 29

is when a river drops the eroded materials its transporting
it happens when a river slows down
-the volume of water decreases
-the amount of transported eroded material increases
-the water is shallower e.g. on the inside of a bend
- river reached the mouth

Question 30

How much of the UK is moorland

Answer 30

1/4

Question 31

Fluvial processes of the upper course

Answer 31

Hydraulic action
V shaped valleys
Waterfalls
Gorges

Question 32

Fluvial processes of middle course

Answer 32

Lateral erosion
Meanders
Ox bow lake
Floodplains

Question 33

Fluvial processes of lower course

Answer 33

Estuaries
Lateral erosion
Levees

Question 34

Upper course features

Answer 34

Marshy boggy land murky water due to suspension upland large bed load narrow shallow cross profile
Fasts and narrow lots of erosion and high turbulence

Question 35

Middle course features

Answer 35

Farmland environment flatter land and floodplains broad and wide river fragments get smaller because of erosion

Question 36

Lower course features

Answer 36

Wide straighter river cab only transport fine materials

Many factories and industries are built e.g. oil petroleum iron steel nuclear

Question 37

Vertical erosion

Answer 37

This deepens the river valley making it v shaped it is dominant in the v shaped high turbulence causes angular particles to be scraped along the river bed causing downward erosion

Question 38

Lateral erosion

Answer 38

Widens river valley during the formation of Meanders

Lower and middle course

Question 39

Discharge

Answer 39

The volume of water flowing in to a river channel

Question 40
