What is the chromosphere?

• The outermost layer of a star's atmosphere

• The apparent surface of a star's atmosphere

• The orange-red layer of a star's atmosphere, between the photosphere and the corona

• The region above the radiative zone of a star

What does the convection zone of a star refer to?

• The shell of cooler hydrogen above a star's core

• The region above the radiative zone where hot gas moves up toward the surface

• The graph that plots luminosity vs. temperature of stars

• The round, sphere-shaped part of a star

What is the corona of a star?

• The shell of cooler hydrogen above a star's core

• The region above the radiative zone where hot gas moves up toward the surface

• The round, sphere-shaped part of a star

• The wide, outermost layer of a star's atmosphere

What does "globular" mean?

• round, sphere-shaped

• a stretched out oval like an ellipse

• a celestial object

• the shape of a planet or star's oribit

What is the Hertzsprung-Russell diagram?
