20pts for question which statement best compares mercury and earth? mercury has very little atmosphere, but earth has an atmosphere consisting of oxygen. mercury is very cold, but earth has moderate temperature to sustain life. they both have liquid water and carbon dioxide in their atmosphere. they both have one moon.

They both have liquid water and carbon dioxide in their atmosphere. This would best compare because they aren't only talking about the physical features of that planet like they are talking about the one moon statement. The second statement is quiet simple and mostly everyone knows about it that Mercury doesn't have the ability to sustain life. The first one could be debated. In my opinion the 3rd one best compares.

it's c. elements are placed in rows based on how may valencies electrons have.
