Quiz on Comets, Meteors, and Meteorites with Answers for 7th Grade.

📚 Quick Study Guide

• ☄️ Comets: Icy bodies that release gas and dust as they orbit the Sun. They have a nucleus, coma, and sometimes a tail.
• 🌠 Meteors: Small particles that burn up in Earth's atmosphere, creating a streak of light (shooting star).
• 🌑 Meteoroids: Small rocks or debris in space.
• 🪨 Meteorites: Meteoroids that survive the trip through the atmosphere and land on Earth's surface.
• 📍 Location Matters: The asteroid belt, between Mars and Jupiter, is a major source of meteoroids.
• 🌡️ Comet Composition: Comets are often described as "dirty snowballs" made of ice, dust, and gas.
• 📐 Orbital Paths: Comets have highly elliptical orbits, taking them far from and then close to the Sun.
