What force caused the hydrogen, helium, and lithium formed from the big bang to collect and form stars, planets, and other objects, as well as to form the different elements than hydrogen making up these objects? magnetism gravity chemical bonds inertia - -gravity What process generates the energy that stars emit? chemical reaction of hydrogen and oxygen to form water vapor- wrong fission of uranium or other large nuclei to form smaller nuclei fusion of hydrogen or other small nuclei to form larger nuclei gravitational acceleration of matter to convert potential energy to kinetic energy- wrong - -fusion of hydrogen or other small nuclei to form larger nuclei Which of these effects is NOT caused by gravity? a planet's atmosphere retaining thermal energy solar systems being held together to form a galaxy planets orbiting a star hydrogen gas condensing to form a star - -a planet's atmosphere retaining thermal energy Which of these properties characterize the outer planets compared to the inner planets? gaseous and less dense smaller size made of high density material a shorter year (shorter amount of time to go around the sun) - -gaseous and
