Answer:
True.
Step-by-step explanation:
An isobar can be defined as an imaginary or physical line drawn on a map and typically used for joining (connecting) places having equal or constant atmospheric pressure.
Also, change in the temperature of various locations on an isobaric map are denoted by wavelike patterns.
An elongated region of warm air aloft (above ground) shows up on an isobaric map as higher heights and a ridge; the colder air shows as lower heights and a trough.
Basically, cold air lofts are directly related to low atmospheric pressure or low heights while warm air lofts represents high atmospheric pressure or high heights.
