Suburbanisation: The growth of towns & cities to include (engulf) surrounding villages/ rural areas.
Urban Sprawl: Unplanned & uncontrolled spread/growth of a city into the surrounding rural area.
Counter-urbanisation: The movement of population away from inner urban areas to a new town, a new estate, a commuter town or a village on the edge or just beyond the city limits/rural–urban fringe.

Land Use Models
Concentric Ring Model: Burgess, based on Chicago
You should be able to explain the pattern shown in the model and identify its weaknesses.
Sector Model: Hoyt
This model introduced the idea that lines of transportation would have a significant impact on land-use zoning. Industry is likely to locate along routes of transportation (road and rail) to receive raw materials and to deliver the final product.
Workers in these industries were likely to live close the industries (lack of transport and perhaps accomodation provided by the industries).
