The essential factor to the initial formation of galaxies, according to the theories describing galaxy evolution, is massive gas and dust clouds collapse. This collapse under the influence of gravity is a key process in the formation of galaxies.
Which factor is essential to the initial formation of galaxies, for either of the theories describing galaxy evolution?(1 point) Responses Small lumps of material merge into larger clumps. Small lumps of material merge into larger clumps. Gravity acts on existing material, shaping it into a new form. Gravity acts on existing material, shaping it into a new form. Massive gas and dust clouds collapse. Massive gas and dust clouds collapse. The force of orbiting stars generates collisions.
