UK'S evolving human landscape Flashcards
what do upland areas of uk consst of
resistant igneous, metamorphic and some sedimentary rocks.
what do low land areas of uk consist of
younger less resistant sedimentary rocks
over 300 million years say the three tectonic processes that have affected rocks in the pennies
the plate on which the uk sits shifted away from the tropics
convection currents beneath the plate uplifted rocks from below the sea - becoming land
during uplift, some rocks snapped and moved along faults in a series of earthquakes over thousands of years. Each movement disturbed the strata so that they tilted. Sometimes the faults from a steep edge (called a fault scarp) where uplift has raised some parts more than others.
aS THE pennines were uplifted , rivers like the wharfe eroded into them creating v shaped valleys . but the most recent ice age , over 10000 years ago, brought huge glaciers to the pennies. They had two effects:
1) Altering river valleys, making them deeper and widening them into U shaped troughs
2) As they melted, the glaciers left features like Malham Cove with a spectacular waterfall!
rocks that make up the uk were formed in different ways. There are three main type of rock:
Igneous
Sedimentary
Metamorphic
igneous rocks
oldest rocks, formed from lavas and deep magmas. Were once molten then cooled and crystalised. Most igneous rocks and resistant to erosion
sedimentary rocks
formed from sediments eroded and deposited by rivers, seas or sea beds. Some are resistant eg limestone while others crumble easily eg shale
metamorphic rocks
are sedimentary rocks that were heated and compressed during igneous activity. Heating and compression harden them and make them resistant - shale becomes slate and limestone becomes marble
what is relief
landscape
what does relief (landscape ) depend greatly on
rock type
to the north of the line and west are uplands of england wales and scotalnd. Here rocks are older, more resistant igneous and metamorphici eyc
to the south and east of the line are lowlands of central and southern england
what makes the ground rough
fragments known as scree
what does scree consist of
of anguar rock pieces created nu freeze thaw weathering.
what else affects valley sides
slope processes
population density
the average number of people in a given area , expressed as people per km squared. It’s obtained by dividing population by area
where do people in the uk live and why
The UK’s population is unevenly distributed
Areas in the north of the UK are more sparsely populated
This is because:
Upland landscapes (e.g. Scottish Highlands) there are not a lot of people because a) the topography make it hard to build in these areas and b) hard to access, so there is a lack of infrastructure here to support a population and investment.
This links to UK physical landscapes! Be synoptic!
Areas n the south of the UK are more densely populated; this could be because of better climate.
Cornwall is sparsely populated as it is difficult to access
East Anglia is very flat, and therefore good for farming – not a lot of jobs here, so no urban population
Many of the cities is where the built up areas are.

Name some of the most populated cities in the UK
The Uk’s major cities eg Birmingham, Manchester, and Glasgow.
Ppl migrate to these cities and regions for work and to spend mone earned there on housing, goods and services. This creates more jobs called the multiplier effect.
As the multiplier effect develops it spreads beyond the city, which becomes a centre of a core region. Cities merge with towns into Conurbations
Explain what conurbation is with examples
is when cities merge with towns.
These then begin to influence a wider area, eg the region from which people commute to work. People earn money in the city, then take it home and spend it locally, boosting a wider region.
Reasons behind the population distribution
What can this map tell us about the UK’s population distribution?
What is the main pattern, and why is this?
Can you spot any anomalies in the pattern?
Many cities have built up near coal fields, their growth due to the industrial growth in these areas.
London – no coal field – had grown due to trade rather than industrial revolution, as well as the Knowledge Economy.
Aberdeen – Since the discovery ofNorth Sea oilin the 1970s, Aberdeen has been known as the off-shore oil capital of Europe.
South coast – Weather, coastal location and some links into London (esp Brighton)
NOTE: Although the Northern region has seen much de-industrialisation,
the core cities like Manchester, Liverpool, Leeds and Sheffield still
help to drive the economy. This concept has been named The ‘Northern Powerhouse’
Reasons behind the population distribution
ANSWERS
1. What is the main pattern, and why is this?
Most urban areas have built up around coal fields e.g. Leeds, Nottingham, Newcastle, Manchester
This is due to industrialisation and the coal powered the industrial activity in these cities attracting people to live and work there.
- Can you spot any anomalies in the pattern?
London – no coal field; built up due to trade
Aberdeen – no coal field; built up due to North Sea Oil
South coast – no coal field; built up due to tourism
Population Density is measured in?
People per square kilometre
What is a conurbation?
A larger urban area that consists of many settlements that have merged together e.g. Greater London. They will be surrounded by a larger, connected region like Hertfordshire, Essex and Surrey.
Why did many of our settlements grow?
Resources - based upon coalfields - and the industrial growth that occurred.
- Why has London grown?
Growth based upon trade (River Thames), close to the EU, well connected globally and investment from many different industries.
Why are places sparse? Give an example
Poor connections (travel and broadband). Fewer industries, physical geography issues like climate and relief (shape of the land) Central Wales, Northern Scotland
Problems faced by the rural periphery
age
Many young people leave rural areas.
This often leaves an ageing population which puts pressure on local services such as the NHS. Older people often retire to rural areas.
Resultant services/facilities maintained do not attract younger (working) people.
brain
Younger, more upwardly mobile people move away in search of better economic and cultural opportunities. This has a negative impact on rural communities and the economy…
lower income
There are fewer jobs opportunities in rural areas and many rural jobs are seasonal or lower paid such as in tourism and farming.
The quality of living is lower here too as a result (lack of accessible/higher quality heath care, education)
Remote Location
This makes transport and communications difficult so ability to trade and access to services becomes limited.
Businesses are hindered as they can’t efficiently communicate.
Transport costs can be very expensive with long distances involved.
