Final answer:
The solar nebula is responsible for the orderly patterns of motion in our solar system. It collapsed under its own gravity and began to rotate faster, forming a disk-shaped rotating nebula.
Step-by-step explanation:
The orderly patterns of motion in our solar system are caused by the solar nebula. The solar nebula did two things to make this occur. First, it collapsed under its own gravity, causing material to fall towards the center and become more concentrated and hot. Second, the collapsing nebula began to rotate faster through the conservation of angular momentum, forming a disk-shaped rotating nebula.
