The points on the earth's surface where the magnetic dip is 90° are __________.

Question 1 of 27070

The points on the earth's surface where the magnetic dip is 90° are __________.

🔍 Key Concepts

• magnetic dip (inclination) and how it changes from equator to poles • the definition of magnetic poles versus magnetic equator • the meaning of isoclinal lines and what value they connect

💭 Think About

• Think about where the earth’s magnetic field lines are vertical rather than horizontal. At what location would a compass needle try to point straight up or straight down? • As you move from the magnetic equator toward the poles, does the dip angle increase or decrease, and where would it reach 90°? • Which of the listed terms describes a specific point or small area on the earth, and which describe lines or broader regions?

✅ Before You Answer

• Be clear on the definition of 90° magnetic dip: that means the magnetic field is straight up‑and‑down, not slanted. • Identify which option refers to points or regions where the field is vertical, rather than lines of equal value. • Eliminate any answer choices that are defined as lines connecting equal dip or equal variation, instead of a specific maximum-dip location.
