Those lines are called the "isotherms".
"iso..." means "same" (like "isometric" exercises")
"therm" means heat or temperature (like "thermal" underwear for camping)
Isotherms are lines on a weather map that connect places with the same temperature, illustrating geographic temperature patterns. They help visualize temperature changes over distances, aiding meteorologists in weather forecasting. The spacing between isotherms indicates how quickly temperature changes in a specific area.
