UK in the 21st Century Flashcards
what is a demographic transition model?
change in population from high birth and death rate to low birth and death rates
define growth corridor
a region of economic growth, often following lines of transport between major cities e.g. M4 corridor
explain lowland UK
low, flatter land with rolling hills with mostly younger sedimentary geology (south and east)
explain upland uk
higher, steeper land with hills and mountains, mostly older volcanic geology (north and west like wales and scotland)
what are lowland areas used for?
settlements, roads and railways- densely populated
what are upland areas used for?
few roads and settlements but beautiful scenery- sparsely populated
describe the pattern of UK rainfall
- highest in north and west (2500mm)
- lowest in south and east (500-625mm)
explain the problems of water stress
- most rainfall occurs in north and west but least rainfall in south and east
- south and east therefore have high demands
- these demands include domestic, industrial and agricultural uses
explain how UK relief rainfall works
- most UK rainfall is caused from prevailing wind blowing from the southwestwhere moist warm air from the atlantic ocean evaporates
- when air carrying moisture reaches upland areas, it is forced up to produce relief rainfall when it condenses into clouds
- the other side of the upland area has little moisture, this is called the rain shadow
describe UK mountain areas
(scotland) have rough pastures and moorlands. the climate is harsh and soil is poor for crops
describe grasslands
(west) ideal for cattle and sheep because of the mild and wet climate
describe arable farmland
dominates majority of uk because of the warm, sunny and dry climate. crops such as cereals and vegetables are found in the south and east
describe coniferous woodland
(northern england scotland and wales) poor soils and remote
describe urban areas
growing/ outwardly sprawling urban development which is caused by population growth
how does population affect life in the UK?
- housing shortages- population rising but only half the houses needed are built a year
- ageing population- high healthcare costs, shortage of places in carehomes/ more expensive, the grey pound- old people join clubs and spend on travel boosting the economy
