Question 1

What are the three main types of map projections in NCERT Class 11?

Accepted Answer

The three main types are cylindrical projections (cylinder touches equator), conical projections (cone touches a parallel), and azimuthal or planar projections (plane touches a point, usually a pole).

Question 2

Which map projection preserves both shape and area?

Accepted Answer

No map projection can preserve both shape (conformality) and area (equivalence) simultaneously. This is a fundamental theorem of cartography — preserving one property inevitably distorts the other.

Question 3

What is the best projection for a world map showing accurate country sizes?

Accepted Answer

Equal-area projections like the Peters (Gall-Peters), Mollweide, or Hammer projections are best for comparing country sizes because they preserve area proportions accurately.
