Answer:
A globe
Explanation:
When we use a globe we can very accurately represent the Earth, its curvature, and with a good scale and coordinate system for the geography. This can be done on a map to an extent but in order for us to put a spherical body on a flat surface, we need to make some changes. This is why on maps you see some parts of continents as larger than they really are.
Advantage: Because of your accent, some people may be interested in you. Not in you particularly, but since your accent sounds nice, they may be interested from where you are and the history of that place.
Disadvantage: Some people may find your accent weird and stuff, you may get bullied and made fun of because of it.
