Paper 1 - UK Physical Landscape Flashcards

1
Q

Describe the formation of Sedimentary Rocks

A
  • Formed in layers called ‘Sediments’

* Formed from small particles that have been eroded and transported and the grains pushed together

CASE STUDY: Chalk Escarpment - North and South Downs) 1) Which area of the UK is it in?

A

Lowland

19
Q

CASE STUDY: Chalk Escarpment - North and South Downs) 2) What rock is it made up of?

A

Sedimentary; Chalk

20
Q

CASE STUDY: Chalk Escarpment - North and South Downs) 3) What was it’s other name?

A

‘Weald-Artois Anticline’

21
Q

CASE STUDY: Chalk Escarpment - North and South Downs) 4) What is it’s shape?

A
  • The top has gentle, rolling hills

* The bottom has a steep scarp slope and dip slope

22
Q

CASE STUDY: Chalk Escarpment - North and South Downs) 4) How was it formed?

A

Giant earth movement caused layers of sediment to be forced upwards forming a chalk dome

23
Q

CASE STUDY: Chalk Escarpment - North and South Downs) 5) How and why has it changed?

A
  • Chemical and Mechanical weathering

* Caused by the last ice age

24
Q

CASE STUDY: Chalk Escarpment - North and South Downs) 6) What did the erosion and weathering form?

A
  • V-shaped valleys
  • Hilltops
  • Ridges
25
Q

What are joints?

A

Vertices cracks

26

27
Q

How do humans use landscapes for agriculture?

A
  • Animal feeding

* Growing food

28
Q

What types of grassland is good for grazing sheep and cows? Why?

A
  • Chalk grassland is good for sheep 》grass is short and full of nutrients
  • Clay grassland is good for cows 》grass is longer
29
Q

Why are lower slopes good for arable framing? Give examples of what can be grown

A
  • They have deeper soil

* Wheat, barley & vine

30
Q

What impacts has farming has on wildlife? (2 good points, 2 bad points)

A

+ Hedgerows provide habitats for bird species
+ Hedgerows form wildlife corridors for bats
- Overfarming
- Chemical farming
