What are planetesimals?

• Small particles

• Stars

• Early forms of planets

• Giant planets

How did planetesimals contribute to the formation of the Solar System?

• They turned into stars

• They left the Solar System

• They formed planets and other bodies

• They became black holes

What effect did the accretion of planets have on the Solar System's disk?

• It had no effect

• It created gaps in the disk

• It expanded the disk

• It made the disk disappear

What happened to many asteroids and comets due to the migration of giant planets?

• They became moons

• They were destroyed

• They were ejected from the Solar System

• They turned into planets
