Detailed explanation-1: -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-2: -The availability of liquid water is the most important factor that makes a planet habitable, because water is a very effective polar molecule and hence an excellent solvent and facilitator for the complex chemistry of life.
Detailed explanation-3: -Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.
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: -Distance of the Earth from the Sun. Importance of light on the Earth. Importance of Earth’s Atmosphere. Importance of Ozone Layer. Favourable Climatic Condition. Water. Force of attraction (Earth’s gravitational pull) 08-Feb-2018
