Question

Which line is drawn on a map to join two places having the same atmospheric pressure at a given point of time?

Answer 1

Isobars: lines of constant pressure. A line drawn on a weather map connecting points of equal pressure is called an "isobar". Isobars are generated from mean sea-level pressure reports and are given in millibars

Answer 2

Isobars lines are drawn on a map to join two places, with the same atmospheric pressure at a given point of time.

These lines are measured according to the level of distance from the ground level and the level of water, which derives the exact distance and calculates the pressure which is being created by the different forces in existence at two places simultaneously.
