Which of the following describe physical properties of moons? Select TWO correct answers. A. Some moons are covered in ice. B. Some moons are covered in craters. C. Some moons have their own ring systems. D. Some moons have a breathable atmosphere.

The correct answers are A and B.<br /><br />A. Some moons are covered in ice. This is a physical property of some moons, such as Europa, which has a thick layer of ice covering its surface.<br /><br />B. Some moons are covered in craters. This is also a physical property of some moons, as they can have impact craters from collisions with other objects in space.<br /><br />C. Some moons have their own ring systems. This is not a physical property of moons, but rather a property of some planets, such as Saturn and Jupiter, which have ring systems around them.<br /><br />D. Some moons have a breathable atmosphere. This is not a common physical property of moons, as most moons do not have an atmosphere that can support human life.
