Relative Age, Absolute Age, and the Law of Superposition

The relative ages of the siblings can be determined in the picture below. Birth order can be determined but the actual or absolute ages can't be determined. The law of superposition states that older rock layers are found under younger rock layers as shown by the arrow. Relative ages of the rock layers below can be determined by observation and applying the law of superposition.. The numbers in the picture below gives the absolute age of the rock layers as determined by some geologists. Figure 4. Draw and label the picture above. Explain what shows relative age, absolute age, and superposition in figure 4. (p. 273/ 15 min) a. Tell what the rock layers show in the picture. b. Tell what the numbers indicate in the picture. c. Tell the concept that the arrow shows in the picture.
