1. The frequency of electromagnetic radiation and
its energy are proportional. This means that high frequency radiation is high-
energy radiation, as well.
2. The word spectrum
is a good way to describe the different types of energy within electromagnetic
radiation due to the fact that the spectrum exemplifies the range of energy.
3. Visible light is useful in plant photosynthesis;
however, other forms of electromagnetic radiation aren’t since visible
radiation can strengthen electrons in chemical bonds; therefore, providing
energy needed for photosynthesis.
4.
A. Inferred radiation, visible radiation, and
ultraviolet radiation.
B. Infrared
radiation is basically heat energy; it keeps living things warms. Visible
radiation can strengthen electrons in chemical bonds; for example:
photosynthesis. Ultraviolet radiation may cause sunburns, various skin
diseases, and can kill bacteria, and ultraviolet radiation is a necessity for
humans.
5. Ultraviolet light is used to sterilize things,
such as protective goggles. Also, UV-C radiation is the most energetic and kills
bacteria and destroys viruses. This is due to the fact that UV-C photons have
enough energy to break covalent bonds.
6. Carbon dioxide and water vapor are two natural
green house gases that absorb infared radiation and reradiate the energy back
to Earth. Typiucally on a nice
day, nearly 90% of visible radiation that is directed toward Earth moves to the
Earth's surface. UV-C radiation is immersed within the stratosphere before it
reaches the Earth's surface.
7. As greenhouse
gases such as carbon dioxide and water vapor are formed, more infrared
radiation is absorbed; therefore, more energy is reradiated on earth's surface,
hotter water affects the hydrologic cycle, and thus, Earth is hotter.
8.
A. Lake water reflects light and absorbs and stores
heat. Asphalt, such as snow, sand, or concrete, warms up when exposed to
sunlight; therefore, heating. This is due to the fact that when solar
radiation strikes these materials, it is reflected and illuminated back into
space.
B. Water acts as
a greenhouse gas and absorbs infrared light and reradiates it back to earth's
surface, then the asphalt directly reflects light sources back up into space.

14. CO2 in the atmosphere, as well as water vapor
help maintain moderate temperatures since they are both greenhouse gases;
therefore, they will absorb infrared radiation and help maintain temperature.
15.
A. Increase the amount of CO2 in the atmosphere:
Natural process:
breathing, bacterial decay
Human process:
agricultural, industrial process and the burning of fossil fuels
B. Increase the amount of CH4
in the atmosphere:
Natural process:
decomposition product of animal waste
Human process: refining
fossil fuels or raising livestock
16. An increase in greenhouse/ atmospheric gases,
which causes higher pressure, would cause the average surface temperature to
increase in the composition of the atmosphere, and the decrease of
greenhouse/atmospheric gases, which causes lower pressure, would cause the
average surface temperature to decrease would be.
17. A green house with transparent glass walls is
much warmer than a structure with opaque wooden walls because the inferred
light would not be able to escape the glass; thus, this is pretty much how
greenhouse gases work.
18.
A. *****
B. *****
19. Atmospheric CO2 gas, solid calcium carbonate found
within limestone, natural gas, and organic molecules.
20. Photosynthesis could be the cause of why carbon
atoms could be part of the atmosphere as a gas; furthermore, they could be part
of the lithosphere due to plant or animal decay.
