layers of the sun
the visible surface of the Sun, lying just above the uppermost layer of the Sun’s interior, and just below the chromosphere.
photosphere
Small dark areas on the Sun's visible surface. They can be as large as Neptune. They form when magnetic fields lines get twists and poke through the photosphere
sunspots
what is scattering?
molecules of dust and gas integer with the incoming solar radiation
How can Solar Flares impact Earth in a negative way?
Trap radio signals, cause satellite problems, impact astronauts, high flying aircrafts
How do solar flares interfere with communication and power systems?
Solar flares produce more intense solar wind—a flow of charged particles. The solar wind thickens and strengthens the ionosphere. Both radio waves from Earth and those traveling to Earth become trapped within the ionosphere and cause interference (static); solar flares sometimes even blackout radio communications.
a layer in the Sun’s atmosphere, the transition between the outermost layer of the Sun’s atmosphere, or corona.
chromosphere
These are charged particles from the Sun they flow from the Corona. They can disrupt radio signals in Earth's Ionosphere
Solar Wind
why is the sky blue?
The blue sky you see on
a clear day is the blue light that has
been scattered away from the line of
sight to the Sun. It scatters shorter wavelengths.
Low solar activity is called the
Maunder minimum.
Explain the term “solar wind.” How does the Sun contribute to “space weather”?
The solar wind is a flow of charged particles from the Sun. The outward flow of these charged particles from the Sun is responsible for “space weather.”
the outermost atmosphere of a star (including the Sun), millions of kilometers in size.
corona
When enormous quantities of ultraviolet light, X-Rays, and radio waves blast out from the Sun
Solar Flares
The reflective property of a nonluminous object. A perfect mirror would have an albedo of 100 percent while a black hole would have an albedo of 0 percent.
albedo
When the Solar Wind encounters Earth’s magnetic field, it excites gases in Earth’s atmosphere it causes?
Aurora
If the Sun stopped producing energy, then all fusion would cease in its
core
where nuclear fusion occurs due intense heat and pressure
core
In 1997 this ______ knocked out satellites that carried telecommunication traffic. It took days to repair and people had no beepers.
Solar Flare
what shields us from most of the damaging ultra violet light?
ozone layer
What devices do we use to see the Sun?
Solar Telescope and orbiting space crafts
The order of colors observed in the visible light spectrum is determined by the
wavelength of the light
the zone where there is a rising and falling of gas currents
convection zone
These are highly magnetic
Sun Spots
Layer in Earth's atmosphere that acts like a mirror, reflecting part of the radio waves back to Earth.
Ionosphere
What is the relation and theory of how Sunspots impact Earth?
They impact Earth's climate
Describe Earth’s energy budget.
The balance between radiant energy received by Earth and radiant energy delivered back into space constitutes Earth’s energy budget. The energy budget for a given location changes from day to day and from season to season. Over the entire surface of Earth and averaged over a period of years, however, the energy budget is very nearly in balance.
