Describe what might happen in rural areas when there is more and more people migrate to urban areas?​

Answers

Answer:

The rural area will be less modern and more run-down.

Explanation:

Think of it like this: City A was once a town with 100 people in it, and requires at least 50 people to maintain it. City B is a city with 500 people in it. Slowly, people from City A move to City B. City A's population may eventually drop down to something below 50. This means that they need more workforce than the citizens can provide. A long period of time with this shortage and the town becomes run-down. Another thing to note is that as the urban areas modernize, City A will take longer to become modernized as there isn't as much demand. This means that City B will advance a lot faster technology-wise while City A may be left behind.

D is not correct because none of the two plates is an oceanic plate.
