1, 2, 3, 4
2, 4, 1, 3
4, 2, 3, 1
21.

Recall that clouds of dust and gas exist in space
The terms axis and contradict are always interchangeable
Evidence is unnecessary when studying Formation of the Solar System
Every model is an exact copy of reality
22.
What happened to the nebula as gravity pulled it inwards?
It collapsed and began to spin faster
It turned into water
It stopped moving
It expanded and cooled
23.
