What substances existed as solid flakes within the inner 0.3 of the solar system before planets began to form?

I think that "0.3" is probably meant to be 0.3 AU. The answer is: the denser substances of the solar system which later formed the rocky inner planets. The gases were likely to form gas giant planets, further away from the Sun.


Why do you compare outer planets to inner planets?

Outer planets and inner planets are compared because they have distinct differences in size, composition, and characteristics. Inner planets are smaller, rocky, and denser, while outer planets are larger, gaseous, and have thick atmospheres. Studying these differences helps scientists understand how planets form and evolve in our solar system.


Why is the moon made of rocks?

Most of the gasses were swept out of the inner solar system by the solar wind, leaving rock as the most abundant material to form planets and moons.

What substances existed as solid flakes within the inner 0.3 of the solar system before planets?

Dust grains, ice particles, and rocky fragments were present as solid flakes in the inner 0.3 AU of the solar system before planets formed. These materials gradually accreted and collided to form planetesimals, which later grew into protoplanets and finally, the inner terrestrial planets we see today.


Why are the inner planets smaller when the outer planets are larger?

By mass, the majority of the matter orbiting the sun is hydrogen and helium. When the solar system was just starting to form heat from the sun and the strong solar wind drove most of the hydrogen, helium, and other gasses out of the inner solar system, leaving behind mostly rock and metal, which were much less abundant. The sunlight and solar wind in the outer solar system were much less intense, so these gasses remained in place long enough to become part of the giant planets.


What substances existed as solid flakes within the inner 0.3 AU of the solar system before planets began to form?

Within the inner 0.3 AU of the solar system before planets began to form, solid flakes of materials such as silicates, metals, and ices would have been present. These materials likely condensed from the hot protoplanetary disk surrounding the young Sun, forming the building blocks that eventually came together to form the planets.

Do comets come from inner realms of the solar system?

No. They form in the outer solar system where it is cold enough.
