| The photographs on the Views of New Jersey site can be used as supplemental teaching tools for undergraduate courses. The following questions may be appropriate for use in courses in photo interpretation, physical geography, geology, ecology, and biology. |
| Exercises |
| Exercise 1. What color is the Highlands region of New Jersey in this photo? What season is it? What type of trees enable you to identify the highlands in this photo - coniferous or deciduous? Is this region generally warmer or cooler than the surrounding area? |
| Exercise 1: Photo |
| Exercise 2. In this color infrared photo, how can you identify the Highlands region of New Jersey? In this late summer/early fall image, what type of trees enable you to identify the Highlands - coniferous or deciduous? Is this region generally warmer or cooler than the surrounding area? |
| Exercise 2: Photo |
| Exercise 3. On this photo, identify the following roads: Interstate 78, Route 22, NJ Turnpike Then identify the following urban areas: Elizabeth, Camden, Philadelphia Does the term "northeast corridor" make sense as a descriptor for the area between Philadelphia and New York City? Why? |
| Exercise 3: Photo |
| Exercise 4. Identify the Pinelands in this photo. Why is it so easy to delinieate the Pinelands in this photo? What is the typical type of vegetation in the Pinelands? |
| Exercise 4: Photo 1 Photo 2 |
| Exercise 5. Locate the following bodies of water: Hudson River, Delaware River, Round Valley Reservoir, Raritan Bay |
| Exercise 5: Photo |
| Exercise 6. Look at these three photos. In which photo is it easiest to identify the water behind the barrier islands of NJ? Why? |
| Exercise 6: Photo 1 Photo 2 Photo 3 |
| Exercise 7. What is the dominant color in these dawn and dusk photographs? Why is this color dominant? How do various wavelengths in the visible portion of the EM spectrum interact with the atmosphere? |
| Exercise 7: Photo 1 Photo 2 Photo 3 |
| Exercise 8. Sunglint on the Delaware Bay nicely distinguished between water from the Delaware River and that from the Bay. Identify each type of water on this photo. What physical principle accounts for our ability to observe this difference? |
| Exercise 8: Photo |
| Exercise 9. A low sun angle allows us to see subtle features in this photograph. In this photo, identify: ripples on the water, haze in the atmosphere, and inland ponds. Based on their shape, what type of clouds dominate in this photo - cumulus, stratus, or cirrus? |
| Exercise 9: Photo |
| Exercise 10. What is the dominant cloud type in this photograph - cumulus, stratus, or cirrus? |
| Exercise 10: Photo |
| Exercise 11. Notice the anvil-shaped clouds forming the frontal boundary in this photo. What type of clouds form this front: cumulonimbus, altostratus, or cirrostratus? |
| Exercise 11: Photo |
| Exercise 12. Distinguish between clouds, fog, and contrails in these photographs. What characteristics allowed you to distinguish between these features? |
| Exercise 12: Photo 1A Photo 1B Photo 2 |
| Exercise 13. Distinguish between snow and clouds in these photographs. What features allowed you to distinguish between these features? In Photo 1, try to identify at least 5 distinct groups of clouds. In Photo 1, which clouds are highest? Which are lowest? How do you know? |
| Exercise 13: Photo 1 Photo 2 |
| Exercise 14. Is it easier to distinguish between clouds and contrails in Photo 1 or Photo 2? Why? Explain how contrails form. Most commercial jet airplanes fly at 35,000 feet. What is the elevation of these contrails? |
| Exercise 14: Photo 1 Photo 2 |
| Exercise 15. Why are there clouds over land in these photos? In these photos, what is the air over land doing - rising or falling? How do you know? In these photos, which is warmer - land or water? How do you know? |
| Exercise 15: Photo 1 Photo 2 Photo 3 |
| Exercise 16. Is this an example of a sea-breeze or land-breeze along NJ and Long Island? Considering the above answer, is it morning or evening in NJ? |
| Exercise 16: Photo |
| Exercise 17. Why is there an uneven covering of snow on the ground in this photo? |
| Exercise 17: Photo |
| Exercise 18. Where are the highest elevations in this photo? What material covers these areas? What physical principle accounts for this phenomena? |
| Exercise 18: Photo |
| Exercise 19. An even blanket of snow covers much of the land in this photo. Yet some areas are brighter than others. What areas are brighter? What physical principle accounts for these differences? |
| Exercise 19: Photo |
| Exercise 20. Based on the pattern of snow in this photograph, identify at least two areas in Manhattan that are (1) highly developed and (2) relatively natural. |
| Exercise 20: Photo |
| Exercise 21. What type of landform is Sandy Hook? How did it form? What is the dominant direction of longshore drift associated with its formation? |
| Exercise 21: Photo 1 Photo 2 |
| Exercise 22. How do barrier islands form? What is the dominant grain size comprising them - sand, silt, or clay? Is the formation of barrier islands associated with sea-level rise or fall? |
| Exercise 22: Photo 1 Photo 2 Photo 3 |
| Exercise 23. Trace the Appalachian Mountains in these photos. |
| Exercise 23: Photo 1 Photo 2 Photo 3 |
| Exercise 24. Identify at least two features that were formed by glacial advance or retreat. How were each of these features created? What is the direction (north, south, east, west) of ice movement in each instance? |
| Exercise 24: Photo 1A Photo 1B |
| Exercise 25. Identify the Watchung Mountains in these photos. What infrastructure is parallel to the trend of these mountains? |
| Exercise 25: Photo 1 Photo 2 |
| Exercise 26. Linear north-south trending ponds dominate the landscape in northern New Jersey. Some of these ponds can be seen in the two photos below. Explain the glacial origin of these ponds? |
| Exercise 26: Photo 1 Photo 2 |
| Exercise 27. Locate an airport in this photograph. Assuming that the longest runway pictured is 4900 feet, calculate the dimensions of this photograph. |
| Exercise 27: Photo |
| Exercise 28. Locate the clouds in this photograph over Manhattan. Draw a line between a few clouds and their corresponding shadows. If the photograph was taken at noon, what is the orientation of the photograph? |
| Exercise 28: Photo |
| Exercise 29. These two photos were taken within seconds of each other. Clouds are clearly visible in one photo but seem to dissapear in the other. Why does this difference exist between the two photos? Which photo was taken from an oblique angle and which one was taken from a near-nadir view? |
| Exercise 29: Photo 1 Photo 2 |
| Exercise 30. These two photos were taken within seconds of each other. Notice how the bright circle in the bottom of each photo migrates from one side of the river to the other. Why does this occur in these high-oblique photos? When might you prefer to use high-oblique photography and when might you prefer to use nadir photography? Consider (1) the utility of sunglint for identifying water bodies and (2) the need to obtain consistent imagery. |
| Exercise 30: Photo 1 Photo 2 |
