Cubangbang's 8th Ch. 4 The Sun Stack #165914

In Genesis 1:16, what is the sun called? Greater light to rule the day.
Distance from the sun to the earth 150 million kilometers
Diameter of the sun 1.4 million kilometers
Why does the moon appear to be as large as the sun? The moon is 400 times closer
The distance from the crest of one wave to the crest of the next wave wavelength
How do rainbows demonstrate that sunlight is composed of wavelengths? Direct sunlight refracts & reflects with prism-like raindrops that produce the entire range of the visible region of the EM spectrum.
93% of the sun's energy; combination of light, x-rays, and radio waves electromagnetic waves
7% of the sun's energy; neutral subatomic particles that can penetrate objects light-years wide as if it wasn't there neutrinos
Shortest electromagnetic wavelength x-rays
electromagnetic wavelengths the human eye can detect ROYGBIV
ROYGBIV red, orange, yellow, green, blue, indigo, violet
Tool astronomer's use to identify chemical elements in an incandescent light source; uses diffraction grating spectroscope
Small microscopic line on glass or plastic; Used in spectroscopes that produces a spectrum much like that produced by a prism Diffraction grating
How much matter does the sun take in our solar system? 99%
What is the sun composed of from most abundant to least? hydrogen, helium, trace elements, and compounds
Most abundant element in the sun; composed of the most hydrogen
Element discovered in the sun before it was found on Earth helium
The sun's surface exists in this state of matter; neither solid, liquid or gas plasma
Visible surface of the sun photosphere
seething convective cells on the sun's surface; caused by hot plasma rising from the interior to the surface granules
dark areas on the surface of the sun; can last several hours; associated with magnetic fields; its movement is evidence that the sun rotates on its axis; appear darker against the sun because it is cooler in temeprature; maximum average of 11 occurs every sunspots
outer brighter portion of the sunspot penumbra
inner darker portion of the sunspot umbra
particularly violent event on the sun also known as a coronal mass ejection; can disrupt telecommunications on Earth solar flares
How much mass in the sun is lost from solar radiation and solar wind? It is evidence of the biblical principle that the heavens are "waxing old like a garment" 5 (radiation) + 1 (solar wind) = 6 million tons lost
layer of ionized particles in the earth's atmosphere caused by solar wind; the more ionizing that takes place in the earth's outer atmosphere, the better the short radio waves are reflected which improves the range of radio broadcasts Ionosphere
Composed mostly of protons and electrons solar wind
Parts of the sun's interior ; not part of solar atmosphere core, radiative zone, convective zone
Part of the sun where thermonuclear reactions are believed to occur core
Disturbances in the sun; streams of plasma that rise up into and descend from the sun's corona; quiescent or eruptive prominences
much higher temperature than the photosphere; Outermost region of the sun's atmosphere corona
Is an instrument that astronomers use to produce an artificial solar eclipse when observing the sun's atmosphere coronograph
Are semiconductor devices used to produce electricity from sunlight; PV cells photovoltaic cells
Disadvantage of solar energy No sun means no power; and sunlight is diffused
Lower layer of the sun's atmosphere chromosphere
Pointed jets on the chromosphere spicules
Region within the sun in which energy travels primarily as electromagnetic waves radiative zone
Are new stars being formed from knots of dust and gas No
