Describe the role of map scale and projections in making maps
|
Map scales and projections are important because they decipher what the map will look like in the end. Map scale shows the feature's size to how it is on the map and projections determine what type of a map it will be
|

|
What type of projection would be best for a world map of population densities? Why?
|
The equal area projection because land masses are the same as in reality. This is useful because it can show the population per square mile accurately across a map
