Question
Chapter 4, Problem 1CR
To determine
The threats that are associated with the many species of amphibians in the world and also determine the reason due to which an individual should neglect hastening the actual extinction of any type of species of amphibian using its activities.
Expert Solution & Answer
Answer to Problem 1CR
Many species of the amphibians are declining at an alarming rate, and a major fraction of these species have already vanished. An individual should be concerned about the extinction of amphibians because the majority of amphibians are of great importance.
Explanation of Solution
There is a great threat to the many species of the amphibians. The frogs, salamanders, and toads are at great risk. The overall increase in the use of insecticides and chemical pollutants are responsible for the overall extinction of the species of the amphibians.
The individual should be concerned about the extinction of amphibians because of some reasons. Those reasons are described as follows:
(i) The majority of amphibians are sensitive and act as the potent biological indicators of various types of changes in the environment.
(ii) The majority of adult amphibians play an important role in the biological communities of the ecosystem.
(iii) Various amphibians act as the potent storehouse of products of pharmaceutical companies. For example- secretion of several amphibians act as the major ingredients of the various pain killers and antibiotics.

Figure 9.9 is a stereogram showing a portion of the area covered by the Whitewater, Wisconsin, topographic map (Figure 9.10, page 160). Use the stereogram and the map to complete the following.
7. The streamlined, asymmetrical hills composed of till, labeled B, are what type of feature?
8. Examine the shape of the features labeled B on the map in Figure 9.10. How can these features be used to determine the direction of ice flow in a glaciated area?
9. Using the features labeled B in Figure 9.10 as a guide, draw an arrow on the map to indicate the direction of ice movement that occurred in this region.
10. What is the likely location of the outwash plain on the map? Identify and label the area "outwash plain." (Hint: Refer to Figure 9.7.)

Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day?
