The density of the sun is most
similar to what planet?
$400
71%
The percentage (by mass) of
the sun that is hydrogen is
$600
About 1 million
Number Earth’s that would fit
inside the sun is

Inward pressure of gravity

in the sun is balanced by

The sun is not a solid surface
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?
$800
The 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
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
Inside to outside
Radiative zone, convective
zone and chromosphere is the
order of the sun’s layers from
the inside out or outside in?
$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?

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

Visible sunspots are in the
$800
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.
