Q

Deviation is the angle between the __________.

🔍 Key Concepts

• True meridian vs. magnetic meridian – what each one represents on a chart and on Earth • Deviation vs. variation – one is caused by the Earth, the other by the ship • Compass card axis – what it actually aligns with when affected by ship’s magnetism

💭 Think About

• First, recall the definition of variation: which two directions is that angle between? Then ask yourself: if deviation is different from variation, which reference must change? • Think about where deviation comes from physically – is it caused by the Earth’s magnetic field or by the ship’s own magnetism? Which part of the compass system is directly affected by the ship? • Look at each choice and ask: does this describe an angle involving the ship’s compass, or just natural Earth directions? Deviation must involve the ship’s compass somehow.

✅ Before You Answer

• Be sure you can clearly define variation and distinguish it from deviation before choosing. • Confirm which term (true meridian, magnetic meridian, or axis of the compass card) refers to the ship’s compass hardware, not the Earth’s field. • Eliminate any choices that do NOT include a ship-related component (like the compass card) for deviation.
