Flashcards in The UK's evolving physical landscape Deck (12):
1

What is igneous rock made from ?

magma (granite)

2

What is sedimentary rock made from ?

compressed sediment (e.g. clay, chalk, limestone)

3

What is metamorphic rock ?

igneous or sedimentary rock changed by heat or pressure (e.g. shale into slate)

4

What is the main rock type in the upland landscapes (top half) ?

igneous and metamorphic rock

5

What is the main rock type in the lowlands (bottom half) ?

sedimentary rock

6

What are the characteristics of chalk ?

- strong

- permeable

- only found in lowland Britain

- forms cliffs at coastlines

7

What are the characteristics of clay ?

- weak

- impermeable

- found everywhere in Britain

- clay landscapes are typically wide, flat plains with lots of lakes, streams and rivers

8

What are the characteristics of granite ?

- hard

- resistant to erosion

- impermeable

- landscapes are badly drained

9

What are the characteristics of metamorphic rocks ?

- very strong

- resistant to erosion and weathering

10

What is slate formed from ?

clay - layers in the clay for weak planes in the slate

11

What is the cause of the differences in upland and lowland areas ?

different physical processes working together

The UK's landscape has been heavily influenced by human activities, name three of them

AGRICULTURE :
- drainage ditches have been built to drain water away from low-lying agriculture to allow crops to grow

FORESTRY :
- uplands have been planted with trees, often for timber production

SETTLEMENT :
- as settlements grew they took over the landscape
- in big cities many rivers/streams run underground
