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.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
