Answer:

Below!

Explanation:

Currently the best theory is <u>the Nebular Theory. </u>This states that the solar system developed out of an interstellar cloud of dust and gas, called a <u>nebula. </u>This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects. <u>The Nebular Theory </u>would have started with a cloud of gas and dust, most likely left over from a previous supernova. The <u>nebula</u> started to collapse and condense; this collapsing process continued for some time. The Sun-to-be collected most of the mass in the nebula’s center, forming a <u>Protostar.</u>

A <u>protostar</u> is an object in which no nuclear fusion has occurred, unlike a star that is undergoing nuclear fusion. A <u>protostar</u> becomes a star when nuclear fusion begins. Most likely the next step was that the nebula flattened into a disk called the Protoplanetary Disk; planets eventually formed from and in this disk.

Three processes occurred with the nebular collapse:

  • Temperatures continued to increase
  • The solar nebula spun faster and faster
  • The solar nebula disk flattened

The orderly motions of the solar system today are a direct result of the solar system’s beginnings in a spinning, flattened cloud of gas and dust.

Hoped this helped.
