People have been trying to understand and predict earthquakes for more than a thousand years. Over time, different earthquake monitoring devices have been invented, such as the seismometer, to track and predict plate movement.
Write a report about these inventions to measure and predict earthquakes. To do so, you will research different earthquake monitoring devices that have been introduced over the years. Here are some questions to guide your research:
What are earthquakes?
What are seismometers?
How did people measure earthquakes before seismometers were invented?
What is a global positioning system (GPS) and how does it track Earth's surface?
How can tracking movement of Earth's surface help to lessen damage from an earthquake?
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 find other Web sites. You also can research earthquake monitoring devices at 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!
