You learned about the Ring of Fire in the article “Volcano!” Find out more about the plates and the forces below Earth’s surface that cause the plates to move and change. Then share what you learn.

The wavy pattern of rock and soil here shows that the Earth has moved over time.

• 1 Frame Questions Decide what questions you want to answer. For example:

  • • Where are the plates located?

  • • What causes the plates to move?

  • • How do the plates move?

  • • What happens when the plates move?

• 2 Conduct Research Find books about geology, the study of the Earth. Use the table of contents to find out if the book has the information you want.

  A table of contents is at the beginning of a book. Most tables of contents list chapter titles, main headings, and page numbers. If any of the contents in the book are about plates, use the listed number to find that section of the book. Read and take notes to answer your questions.
