number of people per unit of area
29
Define sparsely populated
an area with low population density
30
Define densely populated
an area with high population density
31
What are physical factors that influence a sparse population
Harsh areas; mountainous or uneven relief Extreme/harsh climates and bad weather High risk of flooding Infertile soil Locations with frequent natural disasters No water supplies
32
What are physical factors factors that influence a dense population
Flat relief Favorable climates and good weather Availability of natural resources for industry and manufacturing. Fertile land for crops No or few natural disasters Good water supply
33

Describe a dispersed settlement
An isolated, building or a group of two or three buildings, separated from the next by 2 or 3 km
40
Describe a linear settlement
Buildings are strung along a line of communication, for example a main road, a river valley, or canal
41
Describe a nucleated settlement
Buildings are grouped together, initially for defence, or a common resource.
42
What is a site
Describes the physical nature of where a settlement is located – the actual piece of land
43
What is a situation
Describes settlement in relation to other settlements and physical features around it this determines whether the situation will grow into a large city or remain a small town or village
44
What are the factors influencing settlements
Wet point site: this has a good water supply Dry point site: this has less risk of flooding Building material: availability of stone, wood, clay etc. Defensive site: in a river meander or on a hill with steep sided and commanding views Fuel supply: for heating and cooking Food supplies: land suitable for farming Nodal points: where routes converge Bridging point: river shallow enough to build a bridge Aspect: settlements often on sunny side of a valley Shelter: from cold prevailing winds and rain Climate: Good climate attracts more people. Fertile land: brings in more farmers. Location: access for trades and raw materials.
45
Hierarchy
A hierarchy is when settlements are ordered and classifies based on: Population size. Number of services provided. Number of settlements
46
Sphere of influence
An area served by a settlement
47
Services
Facilities that are offered to people e.g. supermarket. Services have a threshold population, which helps explain why bigger settlements have more services.
48
Range
The distance that people are prepared to travel to use a service
49
Threshold population
The minimum amount of people required for a service to be offered and remain open.
50
High Order Goods (Comparison)
Goods that people buy less frequently. They tend to be more expensive and people will normally compare quality and price before purchasing e.g. a car
51
Low Order Goods (Convenience)
Goods that people buy every day. They don't usually cost much money and people would not normally travel far to buy them
52
Rural areas
Tend to have a lot less functions than urban areas. The main purpose of settlements in rural areas is normally agriculture & low-order services. This is because rural areas have less people, poorer transport, poorer communication, less technology, & the land is better used for other purposes.
53
Urban area
tend to have a lot more functions ranging from shopping functions, to educational functions, to transport functions, to administrative functions and residential functions; more middle and high order services.
54
Urban sprawl
The spread or growth of an urban area into the rural-urban fringe; provides mostly middle – order services
55
The CBD
Centre point of the city and has highest land prices Most accessible point in the city High-rise buildings and skyscrapers
56
Land uses in the CBD
Leisure and recreation - may include open land Residential - High/multi-story buildings. Transport - road and rail networks, train stations and airports Business and commerce - offices, shops, and banks Industry - factories, warehouses, and small production centers
57
Why is the CBD in the centre
A central location for road/railways to converge The most accessible location for workers Accessible to most people for shops and businesses
58
Problems that CBD face
congestion, pollution, and lack of space
59
Older inner-city area
Typically found next to CBD Has mainly terraced houses in a grid like pattern
60
Suburbia
Urban sprawl and owning cars led to construction of well-planned and spacious houses Larger than inner city terraces & most have a garden Typically, detached or semidetached Roads are arranged in cul-de-sacs and wide avenues Land prices cheaper than in CBD and inner city Demand can make some areas expensive
61
Outer-city estate
Located on the fringes of cities with varied housing People relocated here when inner city was being redeveloped
62
Rural urban fringe
This is found at the edge of a town or city Mixture of land uses e.g. housing, golf courses, allotments, businesses, parks and airports.
63
Urban Growth/Sprawl
rapid urbanisation, due to building in the rural-urban fringe and land reclamation Problems of urban growth in urban area
