Question
Chapter 11, Problem 1RQ
To determine
The reason for the rocks that are present on the earth could not yield isotopic dates older than 4 billion years.
Expert Solution & Answer
Answer to Problem 1RQ
The rocks on the earth could not yield isotopic dates older than 4 billion years because, they might have undergone melting or metamorphic
Explanation of Solution
The rocks present on the surface of the earth are classified into three types based on their mode of formation: igneous, sedimentary and metamorphic rocks. Isotopic dating is the process of finding the age of the rocks by using the isotopic minerals that are present in the rocks.
By the isotopic dating of meteorites, the age of the earth is calculated as 4.54 Ga. But, the oldest rock on the surface of the earth are dated only 4.0 Ga. This calculated time between 4.0 Ga-4.54 Ga is termed as Haden Eon. The rocks between this period left no mark in the history. The rocks are formed either by the cooling of magma and lava or by the erosion, deposition and compaction of sediments or by the chemical reactions that caused due to high temperature and pressure.

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.
