🔍 Key Concepts

• Magnetic variation (declination) and how it’s shown on charts • Difference between lines of equal variation vs a line where variation is zero • Common chart terms: isogonic and agonic

💭 Think About

• Ask yourself: What does the prefix "iso-" usually mean in navigation and science, and what is being kept the same along those lines? • Think about what special name might be given to the single line where magnetic variation changes sign from east to west (or vice versa). • Consider which term is used for a family of lines on the chart, and which term is used for one specific kind of line.

✅ Before You Answer

• Verify which word applies to all lines of equal magnetic variation on an isomagnetic chart. • Verify which specific term refers to the line where magnetic variation is exactly 0°. • Eliminate any option that is just a descriptive phrase rather than a standard technical chart term.
