Glaciation and Urbanisation, - Coggle Diagram
Factors affecting the rate of urbanisation
Limited opportunities for well-paid employment
Limited services (electricity schools, health care)
Poor transport infrastructure
issues associated with climate change, such as desertification, soil erosion, floods and drought
Prospect of better paid employment
Better schools and health care provision
Friends and family already living in urban areas encourage others to join them
better public transport facilities and access to services such as water and electricity
large market for goods and services e.g street vendors selling food or providing services
More births than deaths
many people living in towns and cities- mainly new migrants are between the ages 18-35
there is a higher birth rate and a high rate of natural increase
the natural increase is likely to increase as the population structure becomes more youthful
A city with a population over 10,000
Tokyo is the largest city in the world with 38 million people
in 2015 there were 28 mega cities. in 2030 there are expected to be over 40
Urbanisation is the result of migration, as people move from the countryside into cities, and
, as birth rates exceed death rates in large cities.

Olympic Park, London
Waters enters cracks, freezes and expands. This repeats until a bit of rock breaks off and collects as scree.
where a glacier moves over an area of rock. Due to friction, the glacier melts and water seeps into cracks around the rocks below. the water refreezes and the rock effectively becomes part of the glacier and is ripped out when the glacier continues to move forward
rocks carried along the river wear down the river bed and banks
