How would i describe the protoplanet hypothesis?
Q. Describe the protoplanet nebular hypothesis. A. This is probably the most widely held theory about how the solar system formed. Very simply, the solar system formed from a cloud of dust and gas (mostly hydrogen gas). Due to gravitation, most of the material (about 90 percent or more) became the sun. Generally, heavier material was drawn to the center, where the sun was, while the lighter atoms remained in the outer regions farther away from the sun. Planets formed from gravitational differences in the outer areas. Small clumps of matter swept up more material and became larger. These bodies collided with each other and grew. Eventually, they became the planets we have today. So planets closer to the sun are generally made of heavier atoms (such as iron) , and those farther away are generally made of lighter atoms (such as sulfur). The planets probably formed about 4.5 billion years ago. Evidence for this hypothesis is in the chemical make up of the planets, and the evidence of crate
