Lines drawn on maps connecting points of equal value?

Lines drawn on maps that connect places with the same value are called isopleths (also known as isolines). This concept lets us see where a variable has the same amount across an area, forming contour-like curves that reveal how the value changes from one place to another. For example, isotherms connect locations with the same temperature on a weather map, while isobars do the same for air pressure. The strength of the lines shows how quickly the value changes: closely spaced lines mean a rapid change, while widely spaced lines indicate a gradual change. The other terms don’t fit because halftone describes a shading technique used to reproduce tones in print, not lines that link equal values. A landform map focuses on representing terrain features rather than linking equal values with lines. Globe gore refers to the segmented pieces used to assemble a globe, not a method for showing equal-value lines on a map.
