- Skidding is when the tire of a vehicle slides on the road without rotating
- If somethings slides on something else then that something is moving against that something else
- Hence, skidding is when the tire of a vehicle moves against the road without rotating

- A road is a kind of object
- A tire is a kind of object
- Hence, a tire and a road are kinds of objects

- Skidding is when the tire of a vehicle moves against the road without rotating
- A tire and a road are kinds of objects
- Friction occurs when two object 's surfaces move against each other
- A surface is a part of an object
- So, skidding causes friction between the tire and the road

- Skidding causes friction between the tire and the road
- Friction causes the temperature of an object to increase
- Therefore, friction causes the temperature of the tire to increase

- If the tire overheats, some chemical in the tire will vaporized
- If the temperature of the tire keeps increasing, the tire will overheat
- So, if the temperature of the tire keeps increasing, some chemical in the tire will be vaporized

- Friction causes the temperature of the tire to increase
- If the temperature of the tire keeps increasing, some chemical in the tire will be vaporized
- So, friction causes some chemicals in the tire to vaporize

- Vaporizing a substance causes smoke
- A chemical is a kind of substance
- Therefore, vaporizing a chemical causes smoke

- Friction causes some chemicals in the tire to vaporize
- Vaporizing a chemical causes smoke
- So, friction causes the tire to produce smoke

So, friction causes the tire to produce smoke
