Could you stand on the surface of the sun? Why or why not?

Red Giant
What is the next stage of the sun as it ages?
$400
11 years in each hemisphere
How long does the sunspot cycle last?
$600
White Dwarf
What will the sun eventually become?
$800The solar cycle is the periodic reversal of the sun’s
magnetic field and occurs over a 22 year period. It equals two sunspot cycles. The north pole
changes to a south pole in 11 years.
What is the solar cycle?
$1000
Describe the future of our Sun?
When all of the Sun's core supply of Hydrogen has been converted into Helium nuclear fusion will stop, gravity will crush the core smaller. The pressure and temperature becomes so great that Helium is converted into Carbon. A red giant is formed as the star color changes from the expanded gases. When all of the core supply of Helium is converted into Carbon, nuclear fusion stops and the core collapses and is now called a White dwarf.

Corona and chromosphere
What layers are visible only during an eclipse?
$400
photosphere
The light we normally see comes from which layer
$600
Red
What color does the chromosphere appear during
an eclipse?
$800
Radiative zone, convective zone and chromosphere is the order of the sun’s layers from the inside out or outside in?
Inside to outside
$1000
It is granulated due to convection currents
What is special about the appearance of the
photosphere?
$200
The core
Where does fusion take place?
$400
The fusion of hydrogen into helium
What is the primary source of the sun’s energy?
$600
Radiation and convection
Energy is transported by what two mechanisms?
$800
It radiates from the core and convects through the photosphere
How does energy move through the sun?
$1000
It will eventually run out of Hydrogen to fuel the nuclear reaction.
Why will the sun’s energy change over time?

These objects come in pairs and represent the north and
south magnetic fields?

Sunspots always appear in pairs and are intense magnetic fields that break through
the surface and are cooler than the area around them. Field lines leave through one sunspot and re-enter through the other one.
Describe sunspots.
$1000
Clouds of gases (from the chromosphere) rise and orient themselves along the
magnetic lines from sunspot pairs. The arches are called prominences.
