The map shows the major rivers, mountain ranges, desert regions, and population densities in China. Mapping the distribution of a population is a geographer’s first step to understanding where people settle and why some areas have greater population densities than other areas. A. Identify what each point symbol on the map represents.
B. Identify TWO topographic features shown on the map.
C. Describe TWO ways that topography affects the spatial pattern of population distribution shown on the map.
D. Describe ONE way that the availability of natural resources may affect population distribution.

The topography of an area has an effect on the area, and, can either increase or reduce the population of the area.

a. Point symbols on a map are used in drawing the features, layout and scenes on a map.  

b. Topographic features on a map are used in showing pipelines, buildings, contours, boundary lines, and the elevation on a map.

c. Topography has an effect on the population of an area. For example, a rugged topography means there's an uneven surface and the surface is rocky. Therefore, this will lead to the reduction of the population as people won't want to settle there.

Furthermore, an undulating topography also leads to a reduction in population.

d. The availability of natural resources in a particular area will bring about a higher population density. This will encourage people to settle in the area and utilize the resources.
