Based on the Nebular theory, which of these is a step in the formation of a new planetary system? (1 point)



evaporation of water

nuclear fission of gases

repulsion of gaseous masses

change of gases into liquids

2. (OSS.01)

A student explains the Nebular theory of formation of planets as follows.


"A cloud of gas and dust in space, called nebula, began to rotate and condensed into a flattened disk. Gravitational force pulled the gas and dust closer together. This resulted in the nuclear fusion of gases and dust to create the sun and planets at the outer flattened portion of the disk."


What is the flaw in the student's explanation? (1 point)



nuclear fission created the sun and planets

the nebula evaporated instead of condensing

the sun was formed at the center of the nebula

gravitational forces kept the gases well separated

The answer is the evaporation of water. As the gas begins to collapse, thermonuclear fusion as a result of the immense gravity at the center of the cloud results in the generation of immense heat and radiation that turns solids and liquid into gaseous form, close to the center of the cloud.




There is a flaw in the statement “This resulted in the nuclear fusion of gases and dust to create the sun and planets at the outer flattened portion of the disk." The sun forms in the center of the cloud since the gravitation effect that drives thermonuclear fusion are strongest in this region. Planets form in the outer regions of the accretion disks where matter attract each other into clumps and gain even more gravitational pull to yank even more matter.
