Which term refers to lines connecting points of equal atmospheric pressure?

The term that refers to lines connecting points of equal atmospheric pressure is "isobars." Isobars are commonly used in meteorology to visualize pressure patterns and help forecasters understand weather systems. By plotting isobars on weather maps, meteorologists can identify areas of high and low pressure, which are critical for predicting wind patterns, precipitation, and overall weather behavior.

Isobaths, in contrast, are related to depth measurements, often in bodies of water, and do not pertain to atmospheric pressure. Isolines is a broader term that refers to any lines on a map that connect points of equal value, but they can represent various phenomena, including elevation or temperature. Isochrones are lines that connect points that are reached at the same time, typically used in transportation and accessibility studies. Each of these terms serves distinct purposes, underscoring why isobars is the specific term relevant to atmospheric pressure.
