Which term refers to lines of constant pressure. Similar to a topographic map and elevations?

• A. Isobars
• B. Station Pressure
• C. SOP
• D. Checklists

Answer: (A)

Lines of constant atmospheric pressure on weather maps are called isobars. They act like contour lines on a topographic map, connecting points that share the same pressure, which helps you read the pressure field and how it changes across an area. When isobars are close together, the pressure changes rapidly, indicating a stronger wind due to a steeper pressure gradient; when they’re spaced farther apart, winds are generally lighter. This representation also helps identify high- and low-pressure centers. The other terms don’t fit because a single station pressure is just the pressure at one location, and SOP or checklists are about procedures, not atmospheric pressure patterns. So the term describing lines of constant pressure is isobars.
