Rust happens when iron meets water and air. Imagine your bike is like a hungry animal, it eats oxygen from the air, and if there's water around, it turns orange. In places that are wet or rainy, rust happens more because the iron gets to eat more.
Examples
- A rusty bike left outside in the rain turns orange faster than one kept dry.
- The kitchen knife that stays wet develops rust quicker than the one you keep dry.
