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 mineral phases?Primarily kamacite and taenite
2. What is the parent body origin?Cores of differentiated asteroids or early planetary bodies
3. How does meteoric iron get to Earth?It forms inside the cores of asteroids. When those asteroids collide or break apart, fragments fly into space and some are pulled in by Earth's gravity.
4. Why is meteoric iron special?It shows unique patterns called Widmanstätten patterns that reveal how it cooled slowly inside its parent body. These patterns help scientists learn about the early solar system.

Kamacite and Taenite: Two iron-nickel alloy mineral phases characteristic of meteoric iron.
Widmanstätten Pattern: Interlocking crystalline patterns observed in iron meteorites after etching, indicative of slow cooling.
Differentiation: The process by which a planet or asteroid separates into layers based on density.
