the interstellar dust attracting heat away from the protosun.
Condensation Theory of the Solar system states that the solar system was formed at about 4.6 billon years ago after nebula reduced in size and flattened out in order to form a circular or oval shape in the form of a disk using interstellar dust particles which consisted of 90% of hydrogen and 9. % of helium particles which attracted heat from the protosun.
The protosun became denser and hotter and experienced gravitational collapse resulting in the formation of the Sun and the Stars. The swirling mass left combined together to form the Planets.

The correct answer is - 4) Rainfall.
The rainfall is crucial and the most important factor that contributes to the formation of the soil. The rainfall has such big influence because of few things:
The water from the rainfall contributes to the weathering of the rocks, thus making them in little sandy pieces.
- plant life
The plant life needs water to exist, and the rainfall provides that. Further, the plants that die are the biggest factor that helps into the soil formation and fertilization.
- animal life
Once there's rainfall and plants, the animals can exist too, and the animals are very import in both the fertilization of the soil, and fertilization of the plants that also fertilize the soil.
The dead plants and animals decompose much quicker and much more efficiently when there's bigger humidity and water, so the rainfall is essential in this process.
'There used to be a number of theories about how the Moon was made and it was one of the aims of the Apollo program to figure out how we got to have our Moon,' says Sara.
Prior to the Apollo mission research there were three theories about how the Moon formed.
Capture theory suggests that the Moon was a wandering body (like an asteroid) that formed elsewhere in the solar system and was captured by Earth's gravity as it passed nearby. In contrast, accretion theory suggested that the Moon was created along with Earth at its formation. Finally, according to the fission scenario, Earth had been spinning so fast that some material broke away and began to orbit the planet.
What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.

According to the condensation theory, the most important factor for the formation of our planets was "the interstellar dust attracting heat away from the protosun".
Condensation is the procedure by which water particles noticeable all around bunch together and shape fluid water. This is regularly observed outwardly of cold glasses. This idea additionally identifies with the solar system.
The condensation theory of the solar system expresses that our solar system, and perhaps all other galaxies, were shaped from a cloud of residue and gas that consolidated into strong issue. Space experts trust that the littlest grains of residue in our cloud applied a draw on the gas about it, 'consolidating' into bigger and bigger bits of issue, similarly as a snowball moving downhill will become bigger and bigger. In the long run, the gravitational draw of these residue atoms was sufficiently solid that they started to pull in each other, developing into greater and greater clusters that had more grounded gravitational pulls. In the long run, these bunches of residue and gas from the cloud frame a star, and potentially planets, space rocks, and comets turning about the star.
