1.) Describe the model of urban structure most often observed in megacities in developing countries. Explain how this model differs from common urban structure in North America. 2.) Describe at least two factors leading to the growth of megacities in developing or least-developed countries.

3.) Identify and explain two factors that led to the formation of squatter settlements in megacities in developing countries.

A. The model of urban structure most often observed in megacities in developing countries is the concentric zone model, the sector model, and the multiple nuclei model. How the models are different is by having different shapes and different columns.

B. The two factors that lead to the  growth of megacities in developing or least-developed countries is migration from rural areas, high fertility rates, and widening of the city's boundaries.

C. The two factors that led to the formation of squatter settlements in megacities in the developing countries is lack of jobs and expensive housing.  Rural to Urban migration is very influential in most megacities settlements and this will lead to squatter settlements. Rural to Urban migration is very common in this part and the more the population the more pressure for the Government to build infrastructure for employment so in that process there will be lack of jobs and even for them to afford normal apartment will be difficult therefore it will lead to squatter settlement for them.

Sorry if it isn't complete

Explanation:

1. Urban structures in developing countries tend to develop into a few megacities while in NA, urban cities stop growing at some points as people move out to surrounding sub-urban areas.

2. One factor is economy of scale in megacities - it requires less infrastructure to satisfy demand when compared to the more spread-out sub-urban. another factor is there are more job opportunities in megacities while in NA, jobs are available outside the urban cities.

3. As megacities grow, there are less space available to build home. That drives up home prices which leads to people staying in squatter areas. Developing countries also have less planning control and are less likely to demolish squatter settlements once they are built.
