Which of the following statements best describes how the planets of the solar system formed?

• They are the remains of an exploded star once paired with the sun.

• They formed from a nebular cloud of dust and gas held together by gravity.

• They are condensed rings of matter thrown off by the young sun.

• The sun captured them from smaller, older stars.

What role did gravity play in Earth's development?

NGSS.HS-PS2-4

Which statement best explains the role gravity played in the formation of the Sun?

• Gravity caused the protoplanetary disk to become a planetismal, which became the Sun. 

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

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

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