Q

Which is TRUE concerning the points on the earth's surface where the magnetic dip is 90°?

🔍 Key Concepts

• Magnetic dip (inclination) – what it measures and how it behaves near poles vs the magnetic equator • Difference between isoclinal lines, magnetic poles, isopors, and magnetic equator on a magnetic chart • How a dip needle (vertical component of the earth’s magnetic field) behaves at different latitudes

💭 Think About

• Think about what happens to a freely pivoting magnetic needle if you move it from the magnetic equator toward a magnetic pole – how does its angle from the horizontal change? • At what specific locations on earth’s surface would that needle end up pointing straight down (90° dip)? • Match each term in the answers (isoclinal line, isopors, magnetic poles, magnetic equator) with what it actually represents on a magnetic chart.

✅ Before You Answer

• Be clear that magnetic dip of 90° means the magnetic field is straight up‑and‑down, not horizontal. • Verify which chart line or feature corresponds to equal dip angles, and compare that to where dip reaches its maximum value. • Confirm the definitions: isoclinal lines (equal dip), isopors (rate of change of variation), magnetic equator (zero dip), and where the magnetic poles fall relative to dip.
