Final Answer:
The features on the surface of the moon have remained relatively unchanged for millions, if not billions, of years.
Step-by-step explanation:
The moon's surface features, such as craters and mountains, have experienced minimal change over an extended period, primarily due to the absence of weather, erosion, or tectonic activity. The lack of an atmosphere and flowing water means that any alterations occur at an extremely slow pace, primarily through occasional impacts from meteorites or comets. These impacts can create new craters but don't significantly alter the overall appearance of the moon's surface on a noticeable timescale.
