Solution
- Presence of Liquid Water: Earth is the only known planet in the solar system where water exists in liquid form on the surface. About 71% of Earth's surface is covered by water, which is essential for life. This makes Earth unique as liquid water is vital for supporting life.
- Atmosphere with Life-Supporting Gases: Earth's atmosphere contains a perfect mix of gases, primarily nitrogen (78%) and oxygen (21%), which is essential for life. It also protects the surface from harmful solar radiation and helps regulate the planet's temperature, creating a stable environment for living organisms.
