GIZMOS: Student Exploration: Earthquakes 1 – Recording Station

Document Content and Description Below

Student Exploration: Earthquakes 1 – Recording Station Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: body wave, earthquake, epicenter, fault, focus, P-wave, S-wave, seismic wave, seismogram, seismograph Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Gizmo Warm-up The Earthquakes 1 – Recording Station Gizmo simulates the seismic waves released by an earthquake. To begin, look at the key on the bottom left side of the Gizmo. 1. The epicenter of the earthquake is the point on Earth’s surface closest to the focus, or origin, of the earthquake. 2. Click Play ( ) and observe the seismic waves leaving the epicenter of the earthquake. Reproduction for educational use only.

I’ve never experienced an earthquake. 2. Earthquakes are usually caused by the sudden movement of rocks along a fault, or fracture, in Earth’s crust. The most famous fault in the U.S. is the San Andreas Fault in California. What major cities are located near the San Andreas Fault? San Francisco and Los Angeles are located near the San Andreas fault. Gizmo Warm-up The Earthquakes 1 – Recording Station Gizmo simulates the seismic waves released by an earthquake.

The most famous fault in the U.S. is the San Andreas Fault in California. What major cities are located near the San Andreas Fault? San Francisco and Los Angeles are located near the San Andreas fault. A. What symbol represents the epicenter? The circle. B. What symbol represents the recording station? The triangle. A. What types of seismic waves are released? P and S seismic waves are released. B. Look at the Recording station detector on the upper left side of the Gizmo. What happens when the seismic waves hit the recording station? When the seismic waves hit the recording station, they’re recorded on the station detector. The P waves aren’t very effective, but the S waves are. An earthquake releases an enormous amount of energy, which passes through Earth’s interior in the form of body waves. There are two types of body waves: P-waves (primary waves) and S-waves (secondary waves). Scientists study earthquakes with the aid of an instrument called a seismograph. When seismic waves reach the seismograph, a graphical record, or seismogram, is produced. Question: How are P- and S-waves shown on a seismogram?
