<u>Answer:</u>
A method of transferring certain portions of the globe to a flat map is a projection is true.
<u>Explanation:
</u>
- In order to protrude down a part seen on the globe on a flat sheet of paper, it is mandatory to make certain adjustments in order to keep the angular and linear measurements intact and undisturbed.
- This process of taking down a part of the globe on a flat sheet of paper is referred to as 'projection'.
- For this projection to be accurate, it is primarily necessary to provide for the differences in angles and distances that may possibly occur depending on which part of the globe is to be projected.
