• rotation

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 starts to collapse because of:

• A nearby star shining it's light
• A passing spaceship
• A passing comet
• Gravity

As a nebula collapses it also begins:

• Expand
• Rotate
• Shake
• Turn to ice

The group of inner planets are known as:

• The Terrestrial Planets
• The Gas Giants
• The Outer Planets
• The Hallow Planets

What caused the lighter elements to leave the terrestrial planets?

• Gravity from the Gas Giants
• Nothing, the lighter elements stayed
• Gravity from the Sun
• Heat from the Sun

The group of outer planets are known as:

• The Terrestrial Planets
• The Gas Giants
• The Inner Planets
• The Rocky Planets

The shape of the planets and dwarf planets after accumulating all their material is:

• Irregular
• A Sphere
• An Oval
• A disk
