question 6 of 10
match each theory of planet formation to its best description.
core accretion theory
gravitational instability theory
gas and dust sticks to itself and collapses
a core of rock and ice attracts gases

Explanation:

• Core accretion theory describes the formation of planets starting with a solid core of rock and ice that gradually pulls in surrounding gases.
• Gravitational instability theory states that dense regions within a protoplanetary disk of gas and dust collapse under their own gravity to form planets directly.

Answer:

core accretion theory — a core of rock and ice attracts gases
gravitational instability theory — gas and dust sticks to itself and collapses
