List three ways the earth and moon are alike?
Answers
ROUND”: They’re both relatively round (oblate spheroids);
SIMILAR TIME OF BIRTH & OF COMPOSITION: They came into existence at relatively the same time (the Moon a bit later; probably due to either a collision of another body with Earth; or because part of the Earth broke away early on). There’s significant similarities between the Moon’s composition and the Earth’s crust’s composition. Both are denser than water (they wouldn’t float).
COLLECTIVELY ORBIT THE SAME “STUFF”: They both orbit around the same center of gravity of the Earth-Moon system; while very gradually drifting apart to some limited extent. And together orbit the Sun. And with it, orbit the center of the Milky Way Galaxy. And with it, are orbiting around a common center of gravity with the Andromeda Galaxy. Our local group is heading somewhere together (the Great Attractor?) And all of “us” are part of the same universe.
LIGHT REFLECTORS: They both reflect light. (Gee, the OP was asking for similarities; how could I leave this one out?? lol)
GOD DIDN’T MAKE EITHER OF THEM: Regardless of the god or gods.
