What critical boundary determined the initial ratio of rock to ice available for accretion by the forming moons?
Answer
The snowline
The snowline represents the boundary within the disk where volatile compounds, such as water, transition from gas to solid ice, thus dictating the material composition available for accretion at different radial distances.
