meteorite
stoney meteorite
iron meteorite
stony-iron meteorite

Explanation:

1. Meteorite: A solid fragment from space (asteroid, comet, or meteoroid) that survives passing through Earth's atmosphere and lands on the planet's surface.
2. Stoney Meteorite: The most common type of meteorite, composed mostly of rocky silicate minerals, similar to Earth's crust and mantle.
3. Iron Meteorite: A meteorite made primarily of iron-nickel alloys, formed from the metallic cores of differentiated asteroids.
4. Stony-iron Meteorite: A rare type of meteorite with roughly equal parts rocky silicate materials and iron-nickel metal, forming at the core-mantle boundary of differentiated asteroids.

For illustrations:

• Meteorite: Draw a rocky/metallic object lying on Earth's ground with a streak (to show atmospheric passage) above it.
• Stoney Meteorite: Draw a rough, rock-like object with a dark fusion crust (from atmospheric heating).
• Iron Meteorite: Draw a dense, metallic-looking object with a smooth, pitted surface (regmaglypts) from atmospheric ablation.
• Stony-iron Meteorite: Draw an object with visible patches of both rocky material and shiny metal.

Answer:

Vocabulary	Definition	Illustration Description
Stoney Meteorite	Most common type, made of silicate rock materials	Rough, rock-shaped object with a dark, melted outer crust
Iron Meteorite	Dense meteorite of iron-nickel alloy from asteroid cores	Shiny, metallic object with small, deep indentations (regmaglypts) on its surface
Stony-iron Meteorite	Rare meteorite with equal rock and iron-nickel components	Object with distinct patches of rocky material and shiny metal sections
