What are dust composition varies?

Dust composition varies because dust can be made of different things depending on where it comes from.

Imagine you're playing in a sandbox, the dust there is mostly sand, which feels rough and gritty under your fingers. But if you're playing near a kitchen, the dust might come from flour or sugar, which feels soft and powdery when you touch it. That’s how dust composition varies, sometimes it's like sand, sometimes it's like sugar.

• In a desert, dust is mostly made of tiny rocks and minerals.
• In the city, dust might be from car parts, bits of paper, or even crumbs from sidewalks.
• At home, dust can come from your pet's fur, your clothes, or even the dirt under your fingernails.

So next time you see dust, it’s not just one kind, it could be a mix of many different things, like a special blend in a cookie jar!
