Question
The lettered descriptions below list the various stages of star and planet formation. Place in the correct order in your post. If any stages are ongoing or occur simultaneously, indicate that by adding an asterisk next to the letter (4pts). 1. Earliest A: Cloud of gas rotates faster and faster as it collapses due to the conservation of angular momentum. B: Motions push smaller grains of material back and forth past larger grains; smaller grains stick to larger Latest grains C: Cloud of interstellar gas starts to collapse under the force of its own self-gravit D: Gravitational potential energy of collapsing gas cloud is converted into heat and radiative energy E: Material makes its final inward plunge, landing on a thin, rotating accretion disk F: Planetesimals continue to accrete material until they become large enough to become planets. G: Planetesimals form that are massive enough to have gravity that begins to attract nearby bodies. H: Inner parts of the flattening cloud begin to fall freely inward, raining down on growing objects at the center 2. Based on the ranking of the stages, write a summarizing paragraph that 'tells the story" of how a planetary system forms. (2pts) After you have completed the ranking and summary, submit your results and compare them to the results that have already been submitted by other students for check back later if there are only a few posts ore you!). Note where you disagree and discuss/comment on it/why your ranking ditters from otherExplanation / Answer
C,A,D,B,H,E,G,F
Stars begin to form when an interstellar cloud begins to contract.
The cloud fragments as it contracts; fragments continue to collapse and fragment until their density is high enough to prohibit further fragmentation.
The fragment heats up enough to radiate a significant amount of energy; it is now a protostar.
The protostar continues to collapse; when the core is dense and hot enough, fusion begins.
The star continues to collapse until the inward force of gravity is balanced by the outward pressure from the core. The star is now on the Main Sequence.
More massive stars follow the same process, but more quickly.
Less massive stars form more slowly
Star formation has been observed near emission nebulae.
Collapse may be initiated by shock waves.
One cloud tends to fragment into many stars, forming a cluster.
Open clusters are relatively young, small, and randomly shaped.
Globular clusters are old, very large, and spherica.
