Mid-Atlantic Ridge (p. 271)


Step 1. Questions

The Mid-Atlantic Ridge is one of the longest mountain ranges on Earth. It is not as well known as the Rocky Mountains or the Appalachian Mountains. That's because almost all of it is at the bottom of the Atlantic Ocean. But there are many scientists, like Ro Kinzler, who are fascinated by it.

Write a report about why scientists are exploring the Mid-Atlantic Ridge. Here are some questions to guide your research:
  • What is the Mid-Atlantic Ridge and how did it form?
  • What do scientists hope to learn from the Mid-Atlantic Ridge?
  • How is the Mid-Atlantic Ridge continuing to change?
  • What do scientists think might happen to the Mid-Atlantic Ridge in the future?
Are you ready? Begin by visiting the Web sites listed in Step 2. Look for answers to the questions above, and write down what you learn in the note-taking boxes.

You may use search engines to research other Web sites. Or research the Mid-Atlantic Ridge in the library. When you are ready, follow Steps 3 and 4 to write your report.


Step 2. Research

Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
