SOLAR SYSTEM

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: -What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Detailed explanation-3: -Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.

Detailed explanation-4: -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-5: -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.
