What is magnitude or luminosity?
A small to medium sized star like our sun
What is a main sequence star?

What are Sunspots?
The surface of the sun and layer we can see
What is the Photosphere?
The force responsible for holding together all of the stars, dust and gas in a galaxy
What is gravity?
The movement of matter and heat due to temperature differences (heat rises)
What is Convection?
The reason why our sun looks so big and bright even though it is an average main sequence star
What is a Apparent Brightness?
The process that converts hydrogen into helium
What is nuclear fusion?
A Star that is not very hot, but extremely big and bright and found it the top right side of the H-R diagram
What is a red supergiant?
The type of Electromagnetic wave is determined by this characteristic
What is wavelength?
The reason why different spots of the sun have different Rotation Period
What is a differential Rotation?
a star that is hot, but very low Luminosity
What is a White dwarf?
The loops of gas that are caused my changes to the magnetic field
What is a prominence?
Shows the relationship between the surface temperature and absolute magnitude of stars.
What is the Hertzsprung-Russell Diagram?
