Astronomers have found evidence of how stars and planets form. They believe that the many
tiny particles in nebulae accrete. This process starts out very slowly and gradually gets faster and
faster. What causes this to happen?
Write Y for yes next to the sentence(s) that help explain the cause; write N for no next to
those that do not help explain the cause.
Each particle gravitationally pulls on nearby particles.
A mysterious unknown force draws the particles toward each other.
Particles collide and stick together making larger particles.
The natural tendency of particles to increase in gravity makes the process speed up.
Larger particles have more mass and more gravitational attraction.
Dark energy makes the particles move toward each other and stick together.
