c. What do you suppose would happen to the large crater if you left it in the rain for 5 minutes (10 times as long)? d. Are there more or fewer overlapping craters here than in the first dish? Make another ÒfingerÓ crater in each of the other two dishes. Place one dish in the rain for two minutes; the other for four minutes. Make sure you pour the water slowly or you will form a lake in the petri dish! 3. a. What has happened to the large craters? Does this agree with your prediction from question 2c? b. Which dish has the most small craters? c. Is there a marked difference between the two dishes, allowing you to easily tell which dish spent the most time in the rain? The angle of illumination affects the visibility of surface features. Surfaces lit from directly overhead (noon time) appear different from those lit at an angle, as during sunrise or sunset. Line up the four petri dishes with their raindrop craters. Turn off the overhead lights. Use the flashlight and shine the light across the surface of the dishes, estimating the illumination angle. Try shining the light from the following angles and describe what you see. Examine the dishes from two locationsÑfrom the position of the flashlight and from directly above the dishes. 4. a. 90¡ (directly above the craters) b. 45¡ c. 20¡ d. 10¡ Examine Figures 6.3 and 6.4. 5. a. Based on Figure 6.3, list the evidence you see on the Moon for long term impact cratering. b. Is the surface shown in Figure 6.4 older or younger than the surface seen in Figure 6.3? How can you tell? 80 Exercise Six: Impact Cratering on a Rainy Day Activities in Planetary Geology for the Physical and Earth Sciences EG-1998-03-109-HQ
*c. What geologic process(es) formed the surface seen in Figure 6.3? What process(es) formed the surface seen in Figure 6.4? Figure 6.3 shows both the limb and the terminator of the Moon. The limb is the horizon, seen in the upper left corner. The terminator is the boundary between the day and night side, seen in the lower right. When examining spacecraft images, scientists are concerned with many aspects of the surface imaged. One aspect of interest is topography, the ruggedness of the surface. Another aspect is albedo, a measure of how the surface reflects light; albedo is a function of the composition and physical properties (such as grain size) of the surface. *6. a. What part of Figure 6.3 gives the best topographic information? Is the illumination angle at this location high or low? b. What part of Figure 6.3 gives the best albedo information? Is the illumination angle at this location high or low? Exercise Six: Impact Cratering on a Rainy Day EG-1998-03-109-HQ Activities in Planetary Geology for the Physical and Earth Sciences 81
