Compare the Earth’s temperature, liquid water resources, mass and atmospheric gases to those on Mars. Do conditions for Earth-like life exist on Mars?
The highest and lowest temperatures recorded on Earth’s surface are 134F and -128F while the figures for Mars are 68F and -220F.
Earth has a great deal of liquid water resources from oceans, inland seas, lakes, rivers and underground water. Mars has no liquid water because of its low atmospheric pressure except for short periods of time at the lowest points on its surface.
Earth’s mass is 5.9736 x 10 (to the 24th power) Kilos. Mar’s mass is 6.4185 x 10 (to the 23rd power) Kilos . This means that Mars has only 11% of the mass of Earth.
Earth’s atmospheric gases consist of about 78% Nitrogen, 21% Oxygen, .93% Argon, .038% Carbon dioxide and 1% Water vapor. This compares to Mar’s atmospheric gases of about 3% Nitrogen, 1.6% Argon, 95% Carbon dioxide, and small traces of Oxygen, Water vapor, and other gases.
Conditions for Earth-like life don’t exist on Mars. There is practically no liquid water on its surface because of the thin atmosphere and other things like solar wind and a lot of ultraviolet light. But our scientists have still not completely ruled out the possibility of some form of life.
