Answer 1

Answer:

Different types of map projections are needed because they all have advantages and disadvantages, so none of them is perfect and they can complement each other.

Explanation:

There are numerous different types of map projections in usage. Each of them has its own set of unique characteristics, and each of them has some advantages, but also some disadvantages. This practially means that none of the maps is perfect and is not able to satisfy everything that is needed of it.

Some map projections have distortion around the Equator, some have distortions around the poles, some don't have distortions but they have shapes that are not suitable for practical usage. This leads to the usage of multiple map projections in order to get all information as objectively as possible instead of using one. If only one map projection is used then everyone will face a problem with wrong information about certain things and having a wrong perception of the world.
