in which order did the events forming our solar system occur?
the solar nebula became hot and dense pulling in more gas. this flattened into a rotating disk. it spun faster and faster,
forming the sun.
gas was pulled toward the center, forming the sun. gas flattened into a rotating disk and became hot and dense, forming
a solar nebula that spun faster and faster.
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.
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 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.

Explanation:

The solar system and the Sun was formed about 4.5 billion years ago.The explosion of a supernova disturbed a cloud of gas and dust in space causes waves in space. This wave squeezed the cloud of gas and dust, and collapsed the cloud that started to spin. The gravity pulled the gas and dust together,  and solar nebula (a giant, rotating cloud of gas and dust) was formed which grew hotter and denser in the center. The surrounding disk of gas and dust was hot in the center. The solar nebula spun faster and faster, and flattened into a rotating disk. This disk got thinner and the particles started to combine together to form clumps, which created planets. Most of the gas was pulled toward the center,  where it became hot and dense, forming the Sun.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
