24
Q
How does ‘age’ affect urban land use?
A
Land uses can change in response to wider socio-economic changes
For example, industrial areas like Battersea Power Station have been regenerated into mixed-use areas.
25
Explain why land value varies across an urban area.
Land has different uses, areas in the city center are more expensive due to accessibility, and the value generally decreases with distance from the center
## Footnote
Limited availability of land in central areas contributes to higher prices.
26
What is the bid rent theory?
The amount of money someone would pay to locate in a given area
## Footnote
It explains why land values are highest in the Central Business District (CBD) due to accessibility.
27
How does the bid rent theory explain the concentric ring model?
The sector that can make the most profit from a location will be closest to the CBD
## Footnote
This results in higher land values in central areas.
28
Summarize how an urban area changes from core to edge in terms of building type, height, and density.
In the core: extremely tall buildings, packed close together; as we move to the edge: buildings become younger, density decreases, height decreases, accessibility decreases, and land becomes cheaper
## Footnote
Environmental quality tends to increase towards the edges.
29
What is the primary characteristic of the CBD?
It is the highest value land populated by retail stores and offices
## Footnote
The CBD has a low residential population due to high bid rent and is accessible via various public transport routes.
30
What can be found in the CBD regarding building height and cost?
In tall buildings, the higher you go, the more expensive it is due to better views
## Footnote
This is a common trend in urban areas where views can significantly increase property value.

34
Why did the working class live close to their workplaces?
Many did not have cars and needed to get to work on foot or by bike
## Footnote
This historical factor contributed to the location of residential areas.
35
How does the density of the Middle Class zone (Zone 4) compare to the Working Class zone?
It is slightly less dense
## Footnote
Middle class residents can afford to live further out from their workplaces.
36
What transportation options do Middle Class residents typically have?
Improved private transport opportunities
## Footnote
This reduces their reliance on public transport accessibility.
37
What are the characteristics of the High Class or Commuter zone (Zone 5a/b)?

42
How does ethnicity contribute to residential segregation?

## Footnote
This can be exacerbated by discrimination and barriers to employment, leading ethnic minorities to have lower income and live in cheaper housing.
43
