Answer 1

Answer:

Option B: Only (iv).

Explanation:

(i) True, because, they are parallel to the equator and run in long circles horizontally. When they come to the end of the Earth, they get even shorter!

(ii) True, because, they travel intersecting the equator for 90°. They run from East to West directions. When they come to the end of the Earth, they get even shorter. They don't have similar radii all the time.

(iii) True, it is the diameter of the whole Earth.

(iv) False, because it is in the bunch the whole meridians of longitudes.
