WHAT IS THE RELATIONSHIP BETWEEN THE ELEVATION AND THE LENGTH OF THE DUST DEVIL TRACKS? THIS QUESTION CAN HELP SCIENTIST SEE HOW THE ATMOSPHERE AT DIFFERENT ELEVATIONS CHANGES THE WAY THE DUST DEVILS EFFECT MARS. THE HIGHER THE ELEVATION THE LONGER THE DUST DEVIL TRACKS WILL BE.
BACKGROUND Dust devil: a small whirlwind containing sand or dust Elevation: the altitude of a place above sea level or ground level.
track- evidence, as a mark or series of marks, that something has passed. The first photographs of dust devils on mars were taken by the Viking orbiter in the 1970's Martian dust devils can be up to 10 times larger than those on Earth.

elevation
1. Find pictures of dust devils on ASU’s website.
2. Write the latitude and longitude of the images and their ID#s if they have them.
3. Put the numbers in the stamps layer to find the image.
4. Find the elevation and length of the tracks using the Mola 128ppd elevation layer.
• The middle elevation with tracks could be the control and we could base everything else off of that one.

Length and Elevation of Dust Devil Tracks on Mars
DISCUSSION • Correlation- No correlation • The data shows that when the elevation changes, it does not
necessarily change the length of the dust devil tracks. • The elevation doesn’t really have anything to do with the wind or
dust/dirt in the area. • We could have measured incorrectly. Because the resource we
used didn’t have many pictures of dust devil tracks, our information could have been wrong.
• It could have changed our graph and could have effected the overall outcome of the research.
CONCLUSION • The higher the elevation, the longer the dust devil tracks will be. No, our
hypothesis was not supported because the data had no correlation. At the highest elevation, the dust devil track was 3.9 km long. At the lowest elevation, the dust devil track was 5.1 km long. At the second lowest elevation, the dust devil track was 5.2 km long. We could have investigated the actual minerals and particles in the dirt and more of the dust devils in one area. I think it is interesting and it could help people better understand dust devils and their tracks. It could also give us more information on mars and what it is like there. http://image.mars.asu.edu/scale?format=jpeg&quality=60&width=400&height=1000&image=/mars/readonly/themis/data/mapping/BROWSE/V382XXBWS/V38206007.png
