The correct answer is D) The Solar Nebula spun faster and faster and flattened into a rotating disk. Most of the gas was pulled toward the center, where it became hot and dense, forming the Sun.
The order in that the events forming our solar system occurred was: The Solar Nebula spun faster and faster and flattened into a rotating disk. Most of the gas was pulled toward the center, where it became hot and dense, forming the Sun.
After many years of research, scientists consider that the Sun is one of more than 100 billion stars in the Milky Way galaxy. It is 109 times the diameter of the Earth and was formed 4.6 billions of years ago. Temperatures at the core of the Sun reach 27 million Fahrenheit degrees, and 10,000 Fahrenheit in the surface.
The other options of the question were A) The Solar Nebula flattened into a rotating disk. As gas became hot and densely formed the Sun, B) Gas pulled toward the center, forming the Sun, and C) Gas flattened into a rotating disk, and became hot and dense, forming a solar nebula that spun faster and faster. Gas was pulled toward the center, forming the Sun.
