match the names and descriptions to the correct phase of a stars life cycle.

red giant
a star whose outer shell has expanded and cooled

supernova
a high-mass star that has collapsed from gravity

a shock wave produced by extremely high temperatures

black hole

white dwarf
a low-mass star that has shed its outer layers

Explanation:

Identify the stellar phases

Using the Stellar Classification knowledge point

• Top-left image: Shows a large, reddish star. This corresponds to a red giant.
• Top-right image: Shows a colorful, energetic cosmic explosion. This corresponds to a supernova.
• Bottom-left image: Shows a dark, warping gravitational sink. This corresponds to a black hole.
• Bottom-right image: Shows a small, dense, glowing stellar remnant. This corresponds to a white dwarf.

Match the descriptions

• red giant: "a star whose outer shell has expanded and cooled"
• supernova: "a shock wave produced by extremely high temperatures"
• black hole: "a high-mass star that has collapsed from gravity"
• white dwarf: "a low-mass star that has shed its outer layers"
