Question

what is the main difference between a meteor, meteorite, and meteoroid
how big they are
where they are found
what they are made of

Explanation:

To determine the main difference between a meteor, meteorite, and meteoroid, we analyze each option:

• A meteoroid is a small rocky or metallic body in space. When it enters Earth's atmosphere and burns up, it becomes a meteor (a "shooting star"). If a portion of it survives the atmospheric entry and lands on Earth, it is a meteorite.
• The key distinction lies in their location: meteoroids are in space, meteors are in Earth's atmosphere (burning), and meteorites are on Earth's surface (after surviving the fall).
• Their size can overlap (e.g., a small meteoroid can become a meteor and potentially a meteorite), and their composition is often similar (rocky/metallic), so "how big they are" and "what they are made of" are not the main differences.

Answer:

B. Where they are found
