Electromagnetic Spectrum
Look at page 219 in your textbook. Then, using detail, describe four ways you
use radiation from the electromagnetic spectrum in your own life. Which ways
are helpful and which can be harmful? Which have long wavelengths (less
energy) and which have short wavelengths (more energy)? Explain. (8 points)

The Power of Convection Currents
Convection currents are all around us! Read the diagrams below to review what
you learned in Chapter 3. Then read pages 238-239 in your textbook and answer
the following questions. (6 points)
Convection currents occur in a pot of boiling water
when water is heated on the stove, rises because it is
less dense, and sinks when it cools.
Convection currents also occur in the
upper mantle when molten rock
(magma) is heated by the Earth’s hot
iron core. The magma rises, and then
sinks as it cools.
“Wildfire Alert” p.238-239
1) Like all winds, Santa Ana winds are created by convection currents. Explain
how the Santa Ana winds form.
2) How do the Santa Ana winds affect vegetation before the outbreak of a fire?
3) What happens when the Santa Ana winds blow during a wildfire?
