CHALLENGE QUESTION #3

*NOTE the new DUE DATE (revised) APRIL 16th!


QUESTION:

Dis-count (ignore, forget about...) one feature that makes Earth 
unique among the planets (but maybe not the moons) of our Solar 
System, and Earth and Mars are almost identical in a certain aspect. 

What do you have to take away from Earth?

In what way are Earth and Mars then alike? 


BONUS QUESTION: 

And as a BONUS...

Whatever do we mean when we say this feature may make Earth 
unique compared to the planets... but maybe not "the moons" of our 
solar system?
