  3. Universe

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A 3-dimensional model of the Earth is called globe. We cannot see the Earth all of it at once as it is so large. So, globe helps us to see what the whole Earth looks like. A globe is better representation of earth in comparison to a flat map. As the Earth spins on its axis, globe also has an axis and we can rotate it. The globe is tilted to one side because the Earth itself is tilted. So, a globe helps in properly studying the Earth.
