What is a SUNSPOT?
Dark area on the sun.Area of intense magnetism
How many sunspot cycles do you see in the Graph?
FIVE Sunspot cycles
What is an aurora?
It is charged particles form the sun hitting the magnetosphere
Does an increase in solar activity affect auroras?
When there is an increase in Solar activity there is an increase of auroras.
What is a solar flare?
solar flareCharged particles ejected from the sun
How is earth affect by solar flares?
Earth is affected by loss of communication, northern lights
Nuclear Fusion reactions that combine with smaller nuclei to form more massive ones are the source of the sun’s energy. True or false
TRUE
What is a prominence?
ProminenceLarge arch into the corona of charge particl
es.
Which stars have the highest absolutes magnitude?
Supergiants have the highest magnitude
By looking at the x-axis and the y-axis, can you tell in which direction do stars move when their temperature and absolute magnitude are the lowest and coolest? (Remember: the higher the number of absolute magnitude the dimmer the star)
Down to the Right
What color of star is most likely found on the main sequence?
Yellow Stars
What type of star, does a main sequence star become when it
loses its energy?
Supergiant ->white dwarf
What two forces have to equal each other for a star to become stable?
Gravity and Fusion
We live in the spiral arm of which galaxy?
Milky way
What is the Big Bang Theory?
Big Bang
The Idea that all matter was created in one massive explosion
What does this chart represent?
– Big Bang
What does cosmological redshift measure?
Outward expansion of the universe
Explain how the presence of cosmic background radiation supports the big bang theory?
We can see the universe was small and warm but has expanded outward and cooled
The expansion of the universe is measured by cosmological redshift. True or False
TRUE
The Doppler Redshift is a measurement of celestial objects
moving outward from Earth.
True OR False
True
What process formed the solar system?
From solar nebula-> gravity forces the nebula to begin fusion-
