When did the solar system begin to form?  

• million years ago

• thousand years ago

• 4 1/2 billion years ago

Why are the inner planets formed mostly out of rocky material?

• because the sun's energy pushed away the gas materials

• because the sun's gravitational force was stronger on the rocky material

• because they were formed from colliding asteroids

Why aren't the outer planets rocky?

• there was not enough rocky material

• their gravity captured the gas that the sun pushed away

• it has the same chemical composition as Earth

The four outer planets are colder than the inner planets because

• they are made of gas

• they are much farther away from the sun than the inner planets

• their gaseous surface reflects the suns energy back toward the sun

The asteroid belt is located between
