Choose the Best Answer
Inner planets formed from dense materials and remained warm due to solar proximity.
Outer planets formed first and attracted materials from the inner region.
All planets formed at the same temperature and distance from the Sun.
Inner planets are primarily composed of ice, while outer planets are rocky.
Understanding the Answer
Let's break down why this is correct
During the Sun’s birth, the space close to it was very hot, so only heavy rocks and metals could stick together. Other options are incorrect because Some people think the outer planets appeared first and pulled stuff from the inner area; It may seem that all planets formed in the same temperature.

Definition
The process of the Solar System's creation, where planets, asteroids, and comets formed from a flat disk of material around the Sun. Inner planets were warmer, smaller, and rocky, while outer planets were colder and larger, with ice mixed in. Gravity from outer planets influenced the movement of ice chunks, leading to the formation and distribution of comets.
