Question

star review
section one - sequencing
the stages below are not in the right order. number the stages in the correct order.
____ the star begins to run out of fuel and expands into a red giant or red super giant.
____ stars start out as diffused clouds of gas and dust drifting through space. a single one of these clouds is called a nebula
____ what happens next depends on the mass of the star.
____ heat and pressure build in the core of the protostar until nuclear fusion takes place.
____ the force of gravity pulls a nebula together forming clumps called protostars.
____ hydrogen atoms are fused together generating an enormous amount of energy igniting the star causing it to shine.

Explanation:

Las estrellas comienzan como nubes difusas de gas y polvo (nebulas). La gravedad forma protostelas. En el núcleo de estas, la fusión nuclear se inicia cuando los átomos de hidrógeno se fusionan. Después, dependiendo de la masa de la estrella, eventualmente se agota el combustible y se convierte en un gigante rojo o supergigante rojo.
