Imagine Earth is like a cozy house. A planet needs the right temperature, enough water, and a protective atmosphere to be a good place for life. If it's too hot or too cold, or if there's no air to breathe, life might not survive.
Examples
- A planet too close to its star is like being in a sauna, water evaporates, and no life can survive.
- A planet with no atmosphere is like being on the Moon, it’s freezing at night and blazing hot during the day.
- If a planet has no water, it's like a desert, no lakes or oceans for life to grow.
