Chapter 10, Problem 1LR

Place the lettered features in proper sequence, from oldest to youngest, in the space provided on the figure.

Summary Introduction

The correct sequence of lettered features.

Introduction:

The scientists have developed many techniques and methods to detect the actual year of Earth. There are two types of data that are used to indicate the geological history of an area. These are relative data and numerical data. The relative data is helpful in determining the correct sequence of the formation of rock layers.

Explanation of Solution

Pictorial Representation: Fig 1 represents the correct sequence of lettered features.

Fig 1: The correct sequence of lettered features (from oldest to youngest).

According to figure 10.24 given in the textbook, the letter featuring K is the youngest while the letter featuring A is the oldest. The letters are representations of rock layers. The layers A, B, C, D, and E are formed first while the layers F, G, H and I are formed latter. M and N are the faults that are responsible for the formation of layers F, G, H and I. The fault N cuts the layer A. K and L are the basalt layers.
