Why do two-dimensional maps of earth have distortions? a. earth is three-dimensional, but maps are two-dimensional b. cartography is an inexact science c. cardinal directions do not apply to two-dimensional maps d. they do not include lines of longitude

Option (A)

Explanation: It is because we cannot represent a three-dimensional object in a two-dimensional maps, without distortion. So in order to reduce this distortion various types of projections are being used such as Mercator projection, Interrupted map projection and Azimuthal projection that helps us in reducing distortion and transform a 3-D object to 2-D.

layer 3 is younger than layer 6.
