GEOL 1120 In-Class Activity – Population Pyramids1. a. Describe the shape of the global population pyramid from 1955 (shown below).The shape shows a pyramid, which means that the population Increasing since there are more younger people than Older people.b. What does the shape of this population pyramid tell you about the population’s growth rate?The growth rate is increasing (positive) since there are more young people.2. a. Describe the shape of the global population pyramid from 2020 (shown below).The shape is positive, however is more stagnant since the Pyramid is steeper and does not increase as much at the Bottom as the previous example does.b. What does the shape of this population pyramid tell you about the population’s growth rate?The growth rate is increasing (positive), but at a slower rate.3. Now examine all the global population pyramids shown below. The years shown are 1955, 1970, 1985, 2000,and 2020.a. How have the shapes of the population pyramids changed over time?The shape gets narrower as time goes on, which can be seen by how there are less and less young people as time goes onb. How has the population’s growth rate changed over time (from 1955 to 2020)?The growth rate has decreased over time, which can be shown by less and less young
