The imaginary lines joining the points of equal atmospheric pressure on a weather map are known as ____________?

Option 1 -> Isotherm: Lines connecting points of equal temperature on a map.

Option 2 -> Isobar: Lines connecting points of equal atmospheric pressure on a map.

Option 3 -> Isobaths: Lines connecting points of equal depth, typically used in bathymetric (underwater) maps.

Option 4 -> Isohyets: Lines connecting points of equal rainfall or precipitation.

Hence, Isobar -> Isobars are the standard meteorological tool used on weather maps to show pressure systems, helping identify high and low-pressure areas that determine weather patterns and wind direction -> correct
