1. Investigating Earth Materials

2.  The title of this photograph is “The Blue Marble”.  What is this blue marble?  Who do you think might have taken this photograph?  Why do you think they named it as they did?

3.  What can you tell about Earth from this photograph?  The Earth is like a spaceship on which we travel.  It has everything we need to stay alive.

4. The Earth has rocks and soil to help us make and grow the things we need.

5. And, that surface is constantly changing.

6. Over two-thirds of the Earth’s surface is covered by water. Think about how many ways we use water.

7. And, that water is constantly moving.

8.  What do we call the blanket of gases that surround the surface of the Earth?  The atmosphere rises above us and provides the air we breathe.

9. The Earth’s atmosphere is constantly changing, too.

10. Man also changes the Earth.

11.  Your mission as an Earth scientist is to learn more about these Earth materials.  By studying the Earth and how it works, we can use and protect these natural resources.  After all, it’s the only Earth that we have.

19. There are many more ways that geoscientists study the Earth. You can learn about some of the these interesting jobs by reading a book or an internet resource.
