Layers of the Sun
In which layer do nuclear reactions occur?
Core
What natural feature is being used to generate electricity?
waterfall, Niagara Falls
What type of radiation did the first stars originally emit most strongly?
ultraviolet
What air mass code represents Continental Polar air?
cP
Protons
Which layer is hotter, the photosphere or the radiative zone?
Radiative Zone
Toward what lake does the Niagara river flow?
Lake Ontario
What color of visible light has the shortest wavelength and which has the longest?
shortest- violet/blue
longest- red
Which air mass source region is located over New York State?
mP
maritime polar
At what temperature does the number of neutron particles dip below the number of helium-4 particles?
1 x 10^9
Why are nuclear reactions able to happen in the core, but not the photosphere?
The core has higher temperatures and pressures
What structure holds water for later use?
pumped storage reservoir
Does longer wavelength radiation have more or less energy?
less
Which ar mass would generally be colder, cP or mT
cP
As time moves away from the big bang, is the temperature increasing or decreasing?
decreasing
A scientist detects an increase in energy leaving the photosphere. Which deeper layer s the most likely source of this increase and why?
The core, because it produces the Sun's energy
Why is water diverted through tunnels?
It runs through turbines to generate electricity
What happened to the light from the first stars as it traveled through space?
It elongated, redshifted
Why are continental air masses generally drier than maritime air masses?
They form over land and so there is less evaporation.
Why were there not more heavier elements in the few seconds after the Big Bang?
It was too hot
Approximately how many times hotter in the core than the photosphere?
2300x
(15,000,000 K / 6500 K)
What type of energy does moving water have before it reaches the turbine?
kinetic
What does redshift tell us about the motion of distant objects?
they are moving away from us?
If a mT air mass moves into New York State during summer, what weather conditions would you expect to occur?
warm, humid
possible clouds and precipitation
At 10,000 seconds after the Big Bang, the relative abundance of helium-3 is about this many times greater than the abundance of lithium-7.
10,000
