Looking closer, we observe other similarities
between Earth and Mars. We have known for a long

features that resemble those on Earth. For example,
both planets experience seasonal dust storms,

of Mars and Earth. Think about how the atmosphere
interacts with the biosphere on Earth. How might
the Martian atmosphere influence the possibility
of life there?
