Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the earth's core structure?Solid inner core (iron-nickel alloy) and liquid outer core (iron-nickel alloy)
2. What is the primary study methods?Seismology, planetary dynamics, and high-pressure mineral physics experiments
3. Why do some planets have magnetic fields?The liquid part of the core moves and creates electric currents, which produce a magnetic field that protects the planet.
4. How do scientists learn about cores when they can't reach them?They use earthquakes, measurements of how a planet spins, and lab experiments that mimic the high pressure and heat inside a core.

Differentiation: The process where a planet separates into layers based on density during formation.
Magnetosphere: The region around a planet dominated by its magnetic field, shielding it from solar wind.
Plate Tectonics: The movement of large plates on a planet's surface, driven by heat from the interior.
Metallic Hydrogen: A theoretical state of hydrogen under extreme pressure, behaving like a metal.
