1) t or f: a greater food surplus allowed for cities to grow in population 2) t or f: concentric zone theory states that an urban area may have many development centers that meet different needs 3) which of the following is a reason why sunbelt cities are increasing in population? a. the sunbelt cities industrialized before northern cities b. sunbelt cities offer fewer tax incentives to businesses c. there are more job opportunities in the sunbelt now d. all of the above

I don't understand the first question     I think 2 is true       3 is all of the above       I'm not sure I'm just answering questions sorry

True. That is one cause of the growth in cities population. By having more food it allowed to feed a major occupancy of citizens.True. The concentric zone theory explains the distribution of social groups within urban areas. Each ring concentrates different land uses. The Central Business District in the middle, then the industrial zone, after that the transition zone which includes residential and commercial uses and so on.C. There are more job opportunities in the Sunbelt now. The sunbelt region is located all across the Southeast and Southwest of the United States. The population began to grow in the late 1960s with people who were seeking a warm and sunny climate. Industries started to settled down there later than other regions and they also have tourism all the year because of the great weather conditions.

  I hope these answers help you.

I'm pretty sure that's called a volcano
