2. Introduction
BACKGROUND

3. Our science question
Is there a relationship between the length and width of cracks?
Are cracks located next to craters?

4. Why is this question important?
We have noticed various cracks that are on top of craters, along edges of craters, and under craters. Different physical features such as length, width, and having little “cracks” coming out the side

5. Hypothesis The longer the crack, the wider the secondary cracks.
The shorter the crack, the smaller the secondary cracks.

6. Background
BACKGROUND

7. Definitions Fault Crack
A planar or gently curved fracture in the Earth's crust across which there has been relative displacement.
Crack
A break without complete separation of parts
Fissure

8. Faults can occur in any orientation and at any angle to horizontal (remember that this angle is known as the dip of the fault), but an active fault's orientation and dip are not necessarily random.
Fault properties are influenced by the regional stress field created by tectonic activity.

12. Experimental Design
BACKGROUND

13. Used the THEMIS camera system from the Mars Odyssey Spacecraft
Visible imagine system
Used THEMIS website to select images of faults and cracks searching within a set location
Used Targeting link to select a location on Mars to image

14. Used the JMARS Program to explore the selected images
Recorded Latitude & Longitude
Record measurements
Width of the crack
At both ends
At the center point
At widest point
At narrowest point
Length of the crack
Add any additional information of interest
Such as closeness of a crater

17. Average Crack Width
The Average Crack Width was calculated by averaging the following data items:
Width at top/left end
Width at bottom/right end
Width at center
Width at widest point
Width at narrowest point

24. Conclusion
BACKGROUND

25. Are cracks located next to craters
Are cracks located next to craters? Investigated 46 cracks, only 12 were near a crater. About a fourth of the cracks that we investigated were near some type of crater. According to our collected data, not all cracks are located next to craters.

26. Initial Research Question: Is there a relationship between the length & width of cracks? Hypothesis: The longer the crack, the wider the secondary cracks. The shorter the crack, the smaller the secondary cracks. Final Data Analysis: While the linear fit showed a positive slope supporting the hypothesis, the r value was low implying that there is insufficient evidence to show a direct correlation.
