Meet Sisir Mondal (pp. 438–439)

Step 1. Questions

Geologists study rocks to see how the rocks are alike and different. Some rocks contain metals, such as chromium and platinum. Classifying rocks helps Sisir Mondal and other geologists learn about Earth.

Write a report about how Sisir Mondal classifies rocks. Before you write, reread the article on pages 438–439 of your textbook. Conduct research to learn more about classifying rocks. Here are some questions to guide your research:
  • What is a rock?
  • What is a mineral?
  • How do igneous rocks form?
  • How do geologists classify rocks?
Are you ready? Begin by visiting the Web sites listed in Step 2. Look for answers to the questions above. Write down what you learn in the note-taking boxes.

With teacher supervision, you may use search engines to research other Web sites. You also can research rocks and minerals at the library. When you are ready, follow Steps 3 and 4 to write your report.

Step 2. Research
