Question #1: Solar energy is created deep within
the of the Sun. It is here that the temperature 27,000,000°
F and pressure. It is so intense that nuclear reactions take place.A).
Corona
B).
Core
C).
Photosphere Question #2: The Sun's outer visible layer is called the
and has a temperature of 6,000°C (11,000°F). This layer has a
mottled appearance due to the turbulent eruptions of energy at the surface.A).
photosphere
B).
corona
C).
core Question #3: Stars are given a designation consisting of a letter and
a number according to the nature of their spectral lines which corresponds
roughly to surface temperature. The classes are: O, B, A, F, G, K, and
M; O stars are the hottest; M the coolest. The numbers are simply subdivisions
of the major classes. The classes are oddly sequenced because they were
assigned long ago before we understood their relationship to temperature.
O and B stars are rare but very bright; M stars are numerous but dim. The
Sun is designated as a star.A).
G2
B).
K1
C).
M1 Question #4: The Sun is personified in many mythologies: the Greeks
called it Helios and the Romans called it .A).
Sol
B).
Helios
C).
Osiris Question #5: The Sun is about billion years old.
Since its birth it has used up about half of the hydrogen in its core.
It will continue to radiate "peacefully" for another 5 billion years or
so (although its luminosity will approximately double in that time).A).
4.5
B).
45
C).
450 Question #6: This part of the sun includes the core and makes up 85%
of the sun's radius.A).
Radiative zone
B).
Convection zone
C).
Corona Question #7: This part of the sun --called the surface'' of sun, is
dense enough gas that we can't see through it and it gives off continuous
radiation. About 5800 Degrees Kelvin.A).
Core
B).
Photosphere
C).
Corona Question #8: This part of the sun can only be studied closely during
eclipses. Very high temperature: 1-2 million degrees Kelvin! But very low
density so it has a low amount of heat. Pearly white color seen in eclipses.A).
Core
B).
Photosphere
C).
Corona Question #9: The fusion process produces the light and heat that come
from the sun. How many billions of tons of Hydrogen does the sun consume
every second ?A).
700
B).
500
C).
300 Question #10: Which part of the sun is the thing you see when you look
at the sun.A).
core
B).
photosphere
C).
convective zone
