Choose one or more: Water is necessary for life as we know it, and life is abundant on Earth from the deepest oceans to the highest mountains. This is because these planets are further away from the solar system, meaning more space debris and which the rings are pretty much left over pieces that were supposed to form with the planet when the solar system was first born.
