Formation of the solar system

A nebula is:

• A cloud of ice
• A cloud of dust and gas
• A cloud of just gas
• A cloud of just dust

The most abundant gases in a nebula are:

• Hydrogen & Oxygen
• Nitrogen & Oxygen
• Hydrogen & Helium
• Oxygen & Helium

A nebula collapses down into a disk known called:

• A compact disk
• An irregular cloud
• An accretion disk

The group of inner planets are known as:

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

What caused the lighter elements to leave the terrestrial planets?

• Nothing, the lighter elements stayed
• Gravity from the Sun

Characteristics of the inner planets include:

• Small, rocky, few or no moons, warm

• Large, rocky and cold

• Small, gaseous, no moons and cold

• Large, gaseous and have many moons

Why did the lighter elements stay in the Gas Giants?

• Just because the solar wind does not affect these planets

• Because they less are dense

• Because the heat from the Sun was not strong enough to affect these planets AND their own gravity kept the gasses in place around them

• Just because their own gravity is strong enough
