• a SUPERNOVA occurs

• When a supergiant explodes

Check all that apply. Which statementS describe the death of stars?

• A star’s final stages of life depend on its mass.

• Stars die when they run out of fuel.

• When a star starts to die, its core expands.

• The outer portion of the star contracts.

• All stars become black holes when they die.

This image shows a nebula. What would most likely be found in a nebula?

• a white dwarf

• a neutron star

• a protostar

• a red giant

Reorder the stages of how stars are born

• Stars are born in clouds of gas and dust called nebulas.

• The gas and dust are pulled together by gravity.

• The pulled-together cloud collapses and becomes hot and dense.

• Heat and pressure cause nuclear fusion, which signals the birth of a star.star bith

The color and temperature of stars are closely related. Which color star is the hottest?

• Yellow

• Red

• Blue

• White

Check all that apply.Which statements describe properties of stars?

• Stars produce energy through nuclear fusion.

• Stars produce energy through gravity.

• Stars are massive objects composed of gas.

• Stars are solid objects that we could stand on.

• Stars are composed primarily of hydrogen and helium.
