Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the disadvantage of a map compared to a globe?
A
A map distorts properties like distance.
B
A map shows little detail.
C
A map indicates actual distances.
D
A map is very large.
Explanation: 

Detailed explanation-1: -Accurate representation: A globe accurately represents the Earth’s curved surface without any distortions in area, shape, distance, direction, or scale. Maps, on the other hand, always introduce some level of distortion due to the process of projecting a three-dimensional surface onto a two-dimensional plane.

Detailed explanation-2: -"On the globe, parallels are equally spaced, but to get the special property of great circles and straight lines, Mercator’s projection exponentially increases the separation of parallels as one moves poleward. On the map, therefore, there is increasing vertical stretching as one moves poleward."

Detailed explanation-3: -There are four main types of distortion that come from map projections: distance, direction, shape and area. The Mercator projection, for example, distorts Greenland because of its high latitude, in the sense that its shape and size are not the same as those on a globe.

Detailed explanation-4: -Because you can’t display 3D surfaces perfectly in two dimensions, distortions always occur. For example, map projections distort distance, direction, scale, and area.
