What is the last step in the formation of the solar system?
The remaining dust and gas are gradually removed from the solar nebula, leaving planets around the sun- a new solar system.

What is the solar nebula beginning to rotate, flatten and get warmer near its center?
The Second Step in the formation of the solar system.
200
What is the difference between a solar nebula and a nebula?
The solar nebula created our solar system and a nebula is a cloud of gas or dust that doesn't become a solar system
300
What is the dust in a nebula made out of?
Carbon and Iron
300
What are the tiny building blocks of the planets?
Planetesimals

What is the fourth step in the formation of the solar system?
Because of their greater gravitational attraction, the largest planetesimals begin to collect more and more of the dust and gas from the solar nebula.
