The Geology Book, Lesson 8

Introduction

These lessons are geared for middle-school students. Each lesson contains a series of questions to answer that pertain to the reading assignment. There is a section of each lesson for advanced students. Teachers should start with the Scripture lesson.

It is important that teachers prepare themselves by reading the stated pages prior to having the student read the assignment. If a child is not able to read yet, parents may wish to read the text to the student.

Text

• Pages 54–57

Scripture

• Psalm 18

Questions

1. What does measuring the chemicals in the ocean tell us about the age of the earth?
2. What does measuring the total volume of the continents and the rate of sediment erosion tell us about the age of the earth?
3. What does the amount of helium in the atmosphere tell us about the age of the earth?
4. What does the rate of decline in the earth’s magnetic field tell us about the age of the earth?
5. What conclusion can be drawn about the age of the earth from the various dating methods discussed in this chapter?

Activity

This is a simple experiment to study wind erosion. Stick a piece of two-sided tape on one side of several different stirring paddles (you can get these from a paint store) and place them in the ground in various places around your home. Make sure they don’t all face in one direction. Have one face North, another South, etc. At regular intervals check the amount of dust or soil sticking to the tape. Depending on the amount of wind and the direction from which it blows, you will see that some paddles collect more dust than other paddles. More soil will stick to the paddles where wind erosion is taking place. What is in the way, preventing dirt from sticking to those paddles where little is collected?
