- Earth is a kind of planet
- The earth rotates on its tilted axis
- Therefore, earth is a planet that rotates on its tilted axis

- Earth is a planet that rotates on its tilted axis
- A planet rotating causes cycles of day and night on that planet
- Therefore, earth rotating on its axis causes the cycle of day and night on earth

Hence, earth rotating on its axis causes the cycle of day and night on earth
Question

Context
- Earth is a kind of planet
