Violent Volcanoes BY: Rachelle A.~ Taylor B. ~ Alina N. ~ Aldrin O. ~ Brennen S. ~ Kit T. http://www.solarviews.com/raw/mars/olympus.jpg
Research Question Where on Mars are the most violent volcanoes located? Our research question is important because our data could tell us if a certain area on Mars has more volcanic activity. If we ever inhabited Mars, we would know where we should not inhabit because of more, or more violent volcanic activity. Our science question is interesting because we get to learn about the size of a lot of the volcanoes on Mars and how violent they erupt. We could also find eruption patterns and know when to predict a big eruption.
Hypothesis Everyone’s Hypothesis - If the location of the volcano determines the violence level, then the most violent volcanoes will be located around 0 degrees longitude and 0 degrees latitude because it is warmer away from the Northern and Southern poles. http://www.akademy.co.uk/mars/images/mars%20face%20and%20north%20ice.jpg

What are volcanoes on Mars? Volcanoes are a vent in the crust of mars through which lava, steam, and ashes are expelled. They are mountain or hill like and usually have a crater at the summit. http://www.geography.learnontheinternet.co.uk/images/nathaz/volcanoxsec.gif
Example of violent volcanoes on Mars This Is a picture of Olympus Mons, the largest volcano on Mars. It is 24 kilometers high, and 550 kilometers wide. We think that this could be one of the more violent volcanoes on mars because it is the largest. http://apod.nasa.gov/apod/ap970915.html
How are volcanoes on Mars formed? Volcanoes on Mars are formed just like the volcanoes on Earth. Volcanoes on Mars are formed when molten rock, or magma underground builds up pressure and spews out of the ground. Larger volcanoes are formed by many eruptions in the same place. http://www.planetpals.com/images/LearnaboutVolcanos.jpg
Spacecraft NASA’s Mars odyssey Camera THEMIS Camera Image Type Visible image- to see details within craters MOLA- to see context of image and depth Geologic Features studied -Volcanoes -lava flows Geologic regions we focused on -The entire map of Mars
Sample Size100 THEMIS IMAGES used to gather data. Categories of Data to be collected and why Image ID #- Keep track of the specific image analyzed Latitude/Longitude- Keep track of locations and their proximity Misc. Data- to record any other interesting information not warranted by our necessary data categories but certainly important to our study Direction of Lava Flow - This can help us because we can know where the violent volcano is located. Distance of lava flow (km) - If there is more lava or if it the lava is longer, this will tell us if it a violent volcano or not. Measurements Rough estimation relative to image parameter based on THEMIS camera’s Visible Image range of 18km

What did your group learn from the data you collected? We learned that most of violent volcanoes are located around 0 degrees Latitude and 270 degrees Longitude because when we did the scatter chart of our data, we took the ones that had the longest lava flow and did another chart to see where it is.. We also learned that most volcanoes have craters near them. And we learned how to tell if it the volcanoes are violent or not.
What would you do to make the investigation better? We could even out the work in our group. We could also have used more images towards our data. We should have add more data to our data chart to show more of where the violent volcanoes are. Or we should have added more information on our methods and prediction.
Explain what scientific questions could branch off of this study to further scientific research about Mars Will the volcanoes erupt any time soon? What the largest lava tube on Mars? Is there any more lava on Mars? What does the distance of the lava tube tell us about the volcano? How does the distance of the lava tube affect the volcano?
