Large molecular clouds will form into protostars because of ____.
A) the thermal motions of the atoms in the gas cloud
B) gravitational contraction
C) radiation pressure from nearby stars
D) the temperature reaching a critical point
E) condensation of dust and gas

Question

Quizplus · Accepted Answer

Gravitational contraction is the primary mechanism by which large molecular clouds collapse to form protostars. As the cloud contracts under its own gravity, the density and temperature increase, eventually leading to the formation of a protostar.
