Gravity played a big role in the formation of the sun, which statement gives a true description.

• Gravity caused the solar nebula to collapse toward the center, causing the center to be dense and hot.

• Gravity caused the small particles to collide to form larger particles called planetesimals, which formed the sun.

• Gravity caused the protoplanetary disk to rotate and form a solar nebula, which became the sun.

Which object below doesn't have a spherical shape due to the lack of gravity and being too small?

• a dwarf planet
• the moon
• an asteroid
• the Earth

Which step is missing in  formation of the solar system? solar nebula, protostellar disk, ___________________, sun, planetesimals, planets

• pluto
• stars
• nuclear fusion
• comets

Why is the composition of the inner planets different from that of the outer planets?

• Inner planets formed from lighter elements.

• The outer planets formed from heavier elements. The lighter elements that were left over formed larger inner planets.

• The inner planets formed from heavier elements. Lighter elements that were left over formed into larger outer planets.
