H-R Diagram
Random
100
These are the 4 main colors observed on the H-R Diagram. 

What are red, blue, yellow, orange, and white?

100

The Lifecycle goes from Nebula, then protostar, main sequence, red giant, planetary nebula, and then finally white dwarf

What are the lifecycle of a low mass (average) star?

100

The white halo(crown) that forms around the sun and can be easily seen during a solar eclipse. 

What is a corona?

100

Using your colored H-R Diagram, determine the type of star that is a luminosity of 10and a temperature of 20,000 K.

What is a blue giant/hypergiant?

100

The aurora borealis is a result of this feature of the Sun. 

What is solar wind?

200

This diagram is used to compare the temperature and true brightness (luminosity) of stars in different life stages. 

What is the Hertzsprung-Russel (H-R) Diagram?

200

This stage occurs when the core of a star has fused all of its hydrogen into helium.

What is a red giant?

200

The layer of the sun where radiation occurs. 

What is the radiation zone?

200

Using your colored H-R Diagram, determine the type of star that is a luminosity of 10and a temperature of 3,000 K.

What is a red supergiant?

200

True or False: The larger the star, the shorter its life. 

What is TRUE?

300
The most common elements in which stars are composed of.
What are hydrogen and helium?
300

The life cycle for a Massive (high/very high mass) star in order. 

What are stellar nebula, massive star, red supergiant, supernova, and neutron star OR black hole?

300

These are temporary regions on the Sun's surface that are cool.

What are sunspots?

300

Using your colored H-R Diagram, determine the type of star that is a luminosity of 10-2 and a temperature of 2,500 K.

What is a main sequence star?

300

Based on the provided image (hey Ms. Evans you need to pull this up), determine the feature of the Sun labeled #9. 

What is a solar flare?

400

This is the feature of a star that determines its true brightness and is a factor in determining the temperature of stars. 

What is luminosity?

400

The joining of two nuclei of hydrogen atoms to form helium with extreme amounts of energy being released.

What is nuclear fusion?

400

This is the visible surface of the Sun that is around 400km thick.  It can reach temperatures near 5800K.

What is the chromosphere?

400

This is the approximate temperature of a red giant star.

What is 5,000 K?

I will also accept between 7,500K-3,000K since they do stretch that far on the scale. 

400

This is the most abundant element in average stars. 

What is hydrogen?

500

The categories represented on the Hertzsprung-Russell Model.

What are white dwarfs, main sequences, giants, and supergiants?

500

This category of stars are dim in color but have very high temperatures despite their small size. 

What is a white dwarf?
500

This is energy created after a solar flare occurs that is sent out into the atmosphere. This can often cause magnetic storms or Northern Lights. 

What is solar wind?

500

This is the final stage of an average mass star and has a temperature of 20,000 K. 

What is a white dwarf?

500

This is the phase of a star shedding its outer layer. 

What is a planetary nebular?
