What makes earth the most unique planet of the solar system?
Answers
1)Our Earth is the third Planet with respect to its distance from the sun. it is neither too close like mercury and Venus not too far like Uranus and Neptune hence it receives just the right amount of heat necessary for life.
2) Although other planets have atmospheres, they are either too thin or too dense, full of poisonous gases thus making it impossible for life to exist .on the other hand Earth'S atmosphere extending upto 1600 km around contains adequate amount of oxygen nitrogen along with a small amount of other gases like Hydrogen Helium and oxygen it acts as a blanket preventing us from the harmful ultraviolet rays of the sun and retains the heat radiated from the Earth's surface.
3) besides its favourable atmosphere, earth's water cycle is its most unique feature .life cannot exist without water.
These make life possible to exist on earth.
