What makes the earths atmosphere able to sustain life compared to the other terrestrial planets?
The main difference between the Earth’s atmosphere and the one of other planets (such as Venus and Mars) is that about 21\% of it is composed by oxygen. Oxygen is a key element to sustain any complex life form on the planet. Both produce oxygen by means of photosynthesis.
Why is Earth’s location in the solar system unique for supporting life as we know it?
In what way is Earth unique among the planets of our solar system? It is the only planet with life. It is the only planet with the right combination of liquid water, unhostile temperatures, correct size, and correct atmospheric conditions to support life.
What type of organisms known on Earth might be able to survive on Europa where there is an ocean covered by ice?
A series of laboratory tests show that some terrestrial bacteria would adapt well to the salty and sulfate-rich ocean believed to exist beneath the hard icy shell of Europa.
