Question

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.
section two - vocabulary
match the word on the left with the definition on the right.
black dwarf
white dwarf a. star left at the core of a planetary nebula
b. a red super giant star explodes
nebula c. what a medium - mass star becomes at the end of its life
d. a large cloud of gas or dust in space
protostar e. exerts such a strong gravitational pull that no light escapes
supernova f. the earliest stage of a star’s life
g. the remains of a high mass star
neutron star
black hole

Explanation:

For the sequencing part, stars start as nebulas, then gravity forms protostars, heat and pressure lead to nuclear - fusion, and eventually stars run out of fuel and change based on mass. For the vocabulary part, we match based on standard astronomical definitions.

Answer:

Section One - Sequencing

1. The star begins to run out of fuel and expands into a red giant or red super giant.
2. Stars start out as diffused clouds of gas and dust drifting through space. A single one of these clouds is called a nebula
3. What happens next depends on the mass of the star.
4. Heat and pressure build in the core of the protostar until nuclear fusion takes place.
5. The force of gravity pulls a nebula together forming clumps called protostars.
6. Hydrogen atoms are fused together generating an enormous amount of energy igniting the star causing it to shine.

Section Two - Vocabulary
