As distance increases, gravitational forces:

• Decrease

• increase

• Disappear

• Stay the same

The Nebular Theory is:

• A theory on how the Milky Way galaxy was formed

• A theory on how the universe was formed

• A theory on how the solar system will be destroyed

• A theory on how the solar system was formed

A nebula collapses down into a disk known called:

• A compact disk

• An irregular cloud

• An Prostellar disk

• An circular disk

The density of gas in a collapsing interstellar cloud is low at first, but ____________________draws matter together until it is concentrated enough to form a star and possibly planets.
