Question 11 of 11 Which model best describes how gravity causes star formation?
A. A long spool of thread is unwound and then wound back up.
B. Two mugs crash into each other and break into many small
pieces.
C. A cup of water is dumped on the ground, where it forms a small
pool.
D. A snowball grows as more snow sticks to it.

D. A snowball grows as more snow sticks to it.

Explanation:

When a star is born, it’s fairly small. However, the stars gravitational pull brings more things (for lack of better term) into it therefore increases it’s size as a snowball would as more things (again, no better term) stick to it.
