A geographical grid has : 1. Lines that run east to west around the globe to mark latitude 2. Lines that run north to south from north pole to south pole indicate longitude Which of the statements given above is/are correct?
- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
Correct answer
Explanation
The correct answer is C, Both 1 and 2. The geographical grid is the network of parallels of latitude, running east to west, and meridians of longitude, running from the North Pole to the South Pole.
Parallels of latitude are circles drawn parallel to the Equator (0°); they measure angular distance north or south, up to 90° at each pole, and become smaller towards the poles. Meridians of longitude are half-circles joining the two poles; they measure angular distance east or west of the Prime Meridian (0°) through Greenwich, up to 180°. Where a parallel and a meridian cross, they fix the exact position of any place on Earth.
A is wrong because statement 2 is also correct.
B is wrong because statement 1 is also correct.
D is wrong because both statements correctly describe the grid.
Exam tip: latitude lines run east–west but measure north–south; longitude lines run north–south but measure east–west.
