Why is a scale model of a system helpful to scientists?
1: Scales models while not an accurate measure for relative size, help to understand distance.
2: Scale models help to understand why moons fall into orbit around planets.
3: Scale models help to understand for relative sizes and distances of planets in actual system.
4: Scale models, while not accurate in measure for relative distance, help to understand size.
P. S: Please answer this as simple as possible.
