Using the nebular theory, explain the formation of our solar system from the formation of the solar nebula through the present day
What will be an ideal response?
Answer: The gases and dust in the solar nebula contracted and began to rotate. The majority of materials fell into the center of this rotating mass to form the protosun. The remaining materials flattened out into a disk, which allowed heat to escape more quickly. Cooling resulted in condensation of larger grains of icy, rocky material. These grains collided repeatedly to create protoplanets, which eventually became the planets we have today.
