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 primary sources of impactors?Fragments from asteroid collisions and debris shed by comets
2. What is the observational limitations?No direct observation of meteors as fireballs or pre-impact discovery has occurred
3. What happens when a rock from space hits Mars?A new crater forms, creating a fresh hole on the surface. The size and shape of the crater show how big the rock was and how fast it was moving.
4. How do scientists find new impact craters on Mars?They look at pictures from orbiters and spot new dark spots that weren't there before. They also use the InSight lander's seismometer to hear the "marsquakes" that come from impacts.

Meteoroid: A small rocky or metallic body in outer space, often a fragment of an asteroid or comet.
Impact Cratering: The geological process by which a celestial body is deformed or excavated by the impact of a meteoroid or asteroid.
Marsquake: A seismic event originating from within Mars, analogous to an earthquake on Earth, detected by seismometers.
Comparative Planetology: The study of planets by comparing their structure, composition, and features with those of other planets.
