Which phrase describes a feature of a Mercator projection Is least commonly used sizes most features to scale present longitude
Komok [63]

Answer:

The correct answers are:

- is most commonly used;

Despite being a projection that is not the best representation, nor the most accurate one, still this map seems to be the most practical one for usage, so it is still the most popular one.

- presents longitude lines as parallel;

This projection is a cylindrical one, so all of the longitude lines are presented are lines that are parallel to one another.

- distorts land size as it moves away from the Equator;

The biggest problem with this projection is the distortion. The distortion becomes bigger and bigger with the increase in latitude, so it depicts the places around the poles as much larger than they actually are.
