The Mercator projection is

  • A.conformal and cylindrical
  • B.equal-area and cylindrical
  • C.conformal and conic
  • D.equal-area and azimuthal

Answer: A

Correct answer: conformal and cylindrical

Mercator is the conformal cylindrical projection, and the two properties are linked in its construction: the parallel spacing is stretched northwards by exactly the amount needed to match the east-west stretching, so that shape is preserved locally. The price is area, which grows without limit towards the poles - a projection can be conformal or equal-area, never both.
