When comparing stars, which color star would have the lowest surface temperature?
Which of the following statement accurately describes the Doppler Effect in stars?
stars coming towards you will be in red shift and stars going away from you will be in blue shift
stars in blue shift are hotter, stars in red shift are cooler
stars coming towards you will be in blue shift and stars going away from you will be in red shift
stars in red shift are hotter, stars in blue shift are cooler
Which two factors are displayed on an H-R diagram? (select two)
distance from Earth
absolute magnitude
stellar zenith
temperature
Which phase of stellar evolution is when stars are in hydrostatic equilibrium?
What solar feature is a permanent protrusion of plasma due to the Sun's magnetic field?
What Sun feature is a temporary outburst of plasma?
Which layer of the Sun is where gases are cycling up and down?
Which layer of the Sun has sunspots?
Which layer of the Sun is where fusion takes place?
Why are sun spots cool?
The Sun's magnetic field gets in the way of hot gas rising to the surface in these areas.
They do not have fusion.
They are areas where absolute magnitude is concentrated.
The solar winds reverse polarization in these areas.
What happens during fusion?
H + H + H + H --> C + extra mass
He + He + He + He --> C + extra mass
H + H + H + H --> He + extra mass
He + He + He + He --> H + extra mass

Which is hottest?
Red Star
Yellow Star
Blue Star
Orange Star
Which stage of the star life cycle is the Sun currently in?
Protostar
Planetary Nebula
Which is brighter: the Sun's absolute magnitude or the Sun's apparent magnitude?
absolute
apparent
neither is brighter- they are the same

Yellow Star
Blue Star
White Star
If the star is FARTHER than 10 parsecs, which is BRIGHTER - its Absolute Magnitude or its Apparent Magnitude?
Which star class is the hottest?

What is a nebula made of? (select all that apply)
gases
dust
rock
liquids
If we are measuring a star's brightness from Earth, we are measuring...
If two stars A and B have the same magnitude, but star A if further away, which star will LOOK less bright to us?
Where are the brightest stars on the HR Diagram?
Why do stars collapse?
their pressure outward is stronger than their gravity inward
their gravity inward is stronger than their pressure outward
their pressure outward is equal to their gravity inward
their gravity outward is stronger than their pressure inward
Where are the class O stars on the HR Diagram?
Where are the coolest stars on the HR Diagram?
Where would a bright, cool star be located on the HR Diagram?
What type of measurement is a lightyear?
