Detailed explanation-1: -High in the atmosphere, the oxygen formed a shielding layer of ozone (O3), which screened out damaging ultraviolet radiation from the Sun and made Earth’s surface habitable. Nearer the ground, the presence of breathable oxygen (O2) opened a door to the evolution of whole new forms of life.
Detailed explanation-2: -Earth is a habitable planet for the following reasons: It is at a perfect distance from the Sun. It has a combination of hydrosphere, atmosphere, and lithosphere that allows life to exist in the biosphere. The ozone layer protects Earth from ultraviolet rays.
Detailed explanation-3: -Life is possible on Earth because the planet has water on its surface and oxygen gas in its air. Earth also has the perfect range of temperatures for life. It is not too hot, like Venus, and not too cold, like Neptune.
