Research Question Where are the most Yardangs located? Why is our science question important?Our science question is important because then,

it will show us the clues to where Yardangs are located and we can find similarities between Earth and Mars.

Why is your science question interesting?Our science question is interesting because it

lets us try to figure out where we could find various places that contains Yardangs.

Hypothesis If there is an area that has lots of erosions…

then the most Yardangs would be found there…because Yardangs are found on surfaces that erode easily.(everyones hypothesis)

If Yardangs are formed from sand particles blown in the wind…then it would be found where sand storms occur…because their found on surfaces that erode easily. (Megan's hypothesis)

MethodsSpace craft NASA’s Mars Odyssey

Camera THEMIS Camera

Image Type Visible Images- to see details within the crater

MOLA- to see context of image and depth

Geologic Features Studied Topic: Yardangs. Yardangs matches our research question because we want to know where we can find the most Yardangs.

Research Question: Where are the most Yardangs located?

Geologic Regions we focused on

All of Mars.

http://themis.asu.eduData collection steps on site:

1. Go to the http://themis.asu.edu website;2. Click on the “image gallery”3. Click on THEMIS image by topic4. Click on Wind/Dust5. Look for pictures of Yardangs Image ID #-Latitude/ Longitude- Misc. Data-

MethodsSample size 120 THEMIS Images used to gather data

Categories of data to be collected and “Why”

Image ID # - We need to know the Image ID # because it would be hard to find a picture without it. We need it for our bibliography too. The Image ID # also identifies each image from each other.

Latitude/ Longitude – We need to know the latitude and longitude of the Yardang images so we can find the exact location of it.

Misc. Data – To record any other interesting information not warranted by our necessary data categories but certainly important to our study

Measurements Picture diameter- rough estimation relative to image parameters based on THEMIS camera’s visible image range of 18km x 30km

HypothesisChristianne-If… there wasn’t any air, no wind, and no sand…-Then… there wouldn’t be any yardangs-Because… for yardangs to form, you need wind and

sand.Megan-If…yardangs are formed from sand particles blown in

the wind..-Then…it would likely be found in a sandstorm, or windy

areas-Because…their formed with lots of wind.

Our paragraph: Most of the points are in the green and near

the equator. They are also mostly in between 90 to 180 longitude range and the -30 and 30 latitude range. The points are clustered together.
