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-
