SOLAR SYSTEM

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: -Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun’s rays.

Detailed explanation-3: -Abstract. 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-4: -No other planet in the solar system has an atmosphere loaded with free oxygen, which is vital to one of the other unique features of Earth: life. Air surrounds Earth and becomes thinner farther from the surface.

Detailed explanation-5: -Animal life as we know it requires an atmosphere with sufficient oxygen. In order for plants to carry out photosynthesis, there must be a sufficient amount of carbon in the atmosphere in the form of carbon dioxide.
