Write true if the statement is true. If the statement is false, change the underlined term to make the
statement true. Write your answers in the spaces provided.
1. An instrument that detects and measures earthquakes is a seismic wave.
2. The place inside Earth where an earthquake starts is called the focus.
3. S Waves are the fastest moving seismic waves from an earthquake.
4. The place on Earth’s crust directly above the place where an earthquake
starts is called the focus.
5. Small movements of Earth’s crust that may or may not be felt are called
tremors.
6. A seismogram is a record of the movements of Earth’s crust.
7. Vibrations released during an earthquake are called focus waves.
8. The Fujita scale is used to represent the magnitude of an earthquake.
9. The higher the lines on a seismogram, the weaker the earthquake.
10. During an earthquake, Earth’s surface shakes hardest at the epicenter.
