The sun is the _____________________________ to the earth. It provides earth’s
adequate heat for life to exist
Temperature= ____________________ Kelvin (K). This is about 9,600 degrees
___________________________(F)
The sun is a ______________________ star
It is composted mostly of the gases ______________________________________________
The earth is about 5,000 Km and you could fit 100 _____________________________
across the sun and over a 1,000,000 earth’s _____________________ the sun to
equal it’s size!
The sun obtains it’s energy through a process called Nuclear __________________.
Nuclear fission powers _______________________________________.
Nuclear fission means
_________________________________________________________________________________________
.
________________________ and __________________________ can be used for nuclear
fission.
Nuclear is about
________________________________________________________________________________________.
Fusion releases enormous amounts of ____________________.
Photosphere= This is considered the __________________________ of the sun
Sunspots= _______________________ that appear on the surface on the surface of
the sun. They appear darker because they are ____________than the surround
areas
• Sunspots occur in an ______________ year cycle
Chromosphere= The chromosphere is the layer above the photosphere. It
appears as a ________________________ glow around the sun and is almost
transparent.
Corona= Which means crown is the outermost layer of gases that surround
the sun. It is only seen during a ________________________________.
• These layers are not seen normally because of the _______________ of the
photosphere
Besides sunspots there are a few other really interesting features that occur
on the sun including:
• _____________________= a steam of charged particles moving away from
the sun at around 400 km/sec
• Solar Prominences= Huge a___________________ (loops) of glowing gas
that extend ___________________ from the sun’s surface
• Solar Flares= ______________________ occurring on the sun. Solar flares
often occur near sunspots.
• Coronal Mass Ejections (______________) = massive burst of solar wind
and magnetic fields that is released into __________________________.
Solar Flares and Coronal Mass Ejections depending on the strength can
actually impact ___________________. Earth has a protective magnetic field that

________________ us from some activities in space, however, sometimes things
disrupt and get through the magnetic field.
• Can cause damage to Earth orbiting _____________________
• Can affect radio ___________________________ and even electricity
• Cause ________________________to be seen on earth (Northern Lights)
Our seasons are impacted by two factors:
• _________________________________________
• _________________________________________________________________________
Earth travels around the sun in an __________________________ pattern so our
distance from the sun is ____________________ what causes our seasons
Our earth is tilted at __________________degrees this is what causes our seasons
• Summer is warmer than winter (in each hemisphere) because the
Sun’s ray hit the Earth at a more _______________________ angle during
summer than winter.
• Days are also much _________________________ during the summer and
_________________________during the winter
Solstice= occur twice a year (______________________________________________)
• Occurs when the tilt of the earth’s axis is pointed directly towards or
___________________ from the sun
• Winter solstice = occurs around Dec 21 and is the
__________________________________of the year
• Summer solstice= occurs around June 21 and is the
______________________________ of the year
Equinoxes occur _____________ a year as well (vernal and autumnal equinox)
• Day light is ______________________to night
• Vernal equinox occurs around March 21 (Spring)
• __________________________ equinox occurs around September 21 (Fall)
All organisms need _________________________ to survive. Some make their own
energy while others have to obtain or ____________________ to get their energy.
Plants get their energy through a process called _______________________________
Photosynthesis = process of absorbing energy from _____________________________
to make food (sugar)
_____________________________________________________________________ (equation for
photosynthesis)
Keep in mind Photosynthesis _____________________ sunlight. Plants absorb
sunlight and _________________________. Turn it into sugar and release
________________________ as a waste product.
