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
