EXAM REVIEW - LANDFORMS OF THE NYC REGION
1. A blank map of the NYC region is shown above.
- On the map, indicate with a dot pattern where, within the five boroughs of NYC, bedrock is either at the surface or just beneath the surface of the land.
- On the map, indicate with a series of parallel lines the area where a series of parallel ridges and valleys would be found.
- One investigator proposes the hypothesis that the parallel ridges and valleys are the result of a landslide. Make a prediction as to what you would find if you were to examine the region that would be a good test of the hypothesis.
I predict that I would find: _________________________________________________________________
- If the area were examined, would the prediction be fulfilled?
In the space below, justify your answer in terms of the real geology of the region. Be as specific as possible.
- Another investigator agrees that the parallel ridges and valleys are the result of a landslide. As a test of the hypothesis, the investigator predicts that loose material will be found directly underneath the surface of the land. In the space below, explain why this prediction is not a strong test of the hypothesis.
- Yet another investigator agrees that the parallel ridges and valleys are the result of a landslide. Asked to make a prediction that will test the hypothesis, the investigator states that landslides are often triggered by earthquakes. Is the investigator's statement a useful test of the hypothesis?
Explain your answer in the space below.
2. Refer to the table below.
|2. Lou, Lulu and their friend Drew are intrigued by a photo of a conical mountain rising from a flat plain.|
|Lou suggests that the hill is a volcano, and predicts that if they look at a contour map, they will see a depression at the top of the hill.|
Lulu suggests it a place where people have dumped the waste material from a nearby quarry. She predicts a map will show a depression caused by people digging for something valuable.
Drew suggests that the hill is all that remains of a once much more extensive high, flat area, much of which has been removed by erosion. She predicts that the map will show a nearby plateau that rises to the same elevation as the top of the hill.
|The actual map is shown to the right. |
Evaluate each of the three hypotheses as 'likely', 'unlikely', or uncertain due to 'no evidence'. Explain your evaluations.
3. In trying to solve a crime, detectives often claim that they use a 'scientific method'. Explain what they mean. Are they correct that their approach is 'scientific'?
4. What depositional agents are likely to form well-sorted deposits?
5. How may ordinary stream deposits be distinguished from glacial meltwater deposits?
