Long-term effects of the solar wind
on Earth are more difficult to observe. Looking for
them requires comparing environmental measurements with
the solar cycle over long periods of time. Unfortunately,
while we have nearly 400 years of sunspot data, there
is little reliable environmental data going back that
To look for long-term effects, you
will examine graphs of six different measurements and
compare them to sunspot numbers for the same time period.
Look for any patterns that suggest the two measurements
might be related in some way.

a connection between sunspot number and the environmental
measurement. Use your observations to answer question
