The process of star and planet formation begins with a large cloud of gas and dust called a solar nebula. rank the formation events that occur within a cloud from earliest to latest.
rank from earliest to latest. to rank items as equivalent, overlap them.
the cloud is large, cool, and slowly rotating
the cloud collapses into a disk
competing rotational and gravitational forces begin to flatten the cloud
the cloud becomes denser, heats up, and rotates faster
the cloud starts to contract under the influence of gravity
