Question

What role did gravity play in the formation of our solar system?

Answer 1

Answer:

Gravity helped to hold things in orbit and create the planets.

Explanation:

Scientist believe that the solar system started in a similar way to stars, from a nebula. They say that the it was a cloud of dust and gas called a nebula that contained mostly hydrogen and helium leftover from the "Big Bang"(which I have my arguments about.) They also say there were heavier elements. Gravity caused the nebula to shrink. As the nebula became smaller it had a rotation. As it got smaller it began to spin faster. The planets were formed by materials cooling off. As they were cooling off they began to clump together. Clumps collided with each other to make a bigger clump. Larger clumps would attract smaller clumps with their gravitational pull. Eventually the clumps started to form the planets and moons in today's solar system.

Answer 2

To keep everything in orbit.
