Sketch area c. Would you expect the ejecta to be of equal thickness everywhere? d. What is the ejecta distribution and thickness in relation to the crater? In the next section of the target tray, produce a crater using the slingshot to launch a steel ball bearing (the same size as above) at 65¡ to the surface. The angle can simply be estimated. The end of the slingshot should still be 70 to 90 cm from tray. Be certain no one is Òdown rangeÓ in case the projectile ricochets. Sketch the crater and ejecta in plan view on the space provided below. Sketch area 2. Is there an obvious difference between the two craters or ejecta patterns? In the third section of the target tray, produce a crater using the slingshot to launch a steel ball bearing (the same size as above) at 45¡ to the surface. Again, estimate the angle. The end of the slingshot should still be 70 to 90 cm from the tray. Be certain no one is Òdown rangeÓ in case the projectile ricochets. Sketch the crater in plan view on the space provided on the following page. As above, label the parts of the crater. 56 Exercise Four: Impact Cratering Activities in Planetary Geology for the Physical and Earth Sciences EG-1998-03-109-HQ
Sketch area In the fourth section of the target tray, produce a crater using the slingshot to launch a steel ball bearing (the same size as the previous exercise) at about 5 to 10¡ to the surface. Again, estimate the angle, and make sure not to hit the rim of the tray. The end of the slingshot should still be 70 to 90 cm from tray. Be sure no one is Òdown rangeÓ in case the projectile ricochets. Sketch the crater in plan view and cross section on the space provided below. Sketch area Examine the sand craters and your sketches. 3. How does ejecta distribution change with impact angle? Examine Figure 4.1, a photograph of the lunar crater Messier. 4. a. Was this a high angle or low angle impact? b. Did the meteoroid which formed Messier impact from the east or west?
