Why is the mass of the earth important to maintain life as we know it?
A) If we had more or less mass, the earth would not have plate tectonics and would be covered entirely by water.
B) If the earth's mass were significantly different, we would be bombarded by cosmic rays that would strip away our atmosphere.
C) If the earth's mass were greater, we would be bombarded by meteorites and if it were smaller, we would not be able to hold the moon in orbit.
D) If it had more or less mass, the atmosphere would be very different with either too much ammonia and methane or too little oxygen and water.
