Which is NOT a layer of the solar atmosphere?
photosphere
chromosphere
stratosphere
corona
The photosphere has a temperature of about
500,000 K
2 Million K
5,800 K
3,000 K
The temperature of the photosphere is determined precisely by:
measuring the spectrum of sunlight then using Wein's Law
using a thermometer attached to a spacecraft
running algorithms from a computer simulation
estimating the temperature required to burn coal, which is what the sun is made up of
The Sun makes its energy by:
burning fossil fuels
nuclear reactions in the core
shining light
photosynthesis
The Sun's visible surface, the ______, is the layer in the sun from which visible photons most easily escape.
corona
chromosphere
photosphere
entire atmosphere
Which is true?
The sun is gaseous from its outer atmosphere right down to its center
The sun is mainly gaseous but has a solid core
The sun's chromosphere is gaseous, but the photosphere is a solid surface on fire
The sun's atmosphere is gaseous and the surface is a boiling liquid
Much of the light generated below the photosphere...
cannot escape because it is blocked by dense gases
is so bright that we are unable to see the photosphere itself
__________ show that the Sun's photosphere contains atoms of hydrogen, helium, and other gases.
absorption lines
emission lines
granules
magnetic fields
The photosphere's mottled appearance, with regions with dark edges, is called:
limb darkening
granulation
spiculation
color pixelation
The center of a photospheric granule is:
sinking gas because it is hotter than the gas on the edges of the granules
rising gas because it is hotter than the gas on the edges of the granules
sinking because it is cooler than the edges of the granules
sinking because it is hotter than the edges of the granules
The speeds of rising and sinking of gases in the sun's photosphere is measured using:
doppler shifts of spectral lines.
Wein's law.
High speed cameras.
robots that we send to the sun.
granulation is the surface effect of:
conduction
convection
poor visibility
rotating hurricanes
The layer directly above the photosphere is called the _____.
chromosphere
corona
core
radiative zone
How can you see the chromosphere?
Anytime, with binoculars
During a solar eclipse, with an unaided eye
During a solar eclipse, but only with special eclipse goggles
During a lunar eclipse, with a special lense on a telescope
The chromosphere is _____ due to ______.
yellow... sulfur gas
pink... red, blue, and violet Balmer lines.
white... red, yellow, green and blue gases
blue... the high temperature
Filtergrams of the chromosphere reveal _____, which are flame-like structures extending into the lower corona.
granules
spicules
limbs
The ____ is the sun's outermost atmospheric layer that extends many solar radii from the visible sun.
photosphere
corona
exosphere
chronosphere
What is the solar wind?
a breeze of low-density ionized gas streaming from the Sun's corona.
wind generated from rotation of the sun.
a breeze originating from the sun's magnetic fields.
another term for "light"
Which is true about temperature of the solar atmosphere?
Temperature decreases from the photosphere to the corona
Temperature increases from the photosphere to the corona
Temperature stays relatively consistent within the solar atmosphere
Temperature increases then decreases in the corona
The hottest layer of the sun's atmosphere is its:
innermost layer, the photosphere
outermost layer, the corona
middle layer, the chromosphere
