How does this seismogram differ from the one you first investigated? Northwestern University. One of the most useful resource available is 24/7 access to study guides and notes. Measure difference in P- and S-wave arrival times, then use data from the Earthquakes 1 - Recording Station Gizmo to find the distance of the epicenter from each Lesson Info. Scientists study earthquakes with the aid of an instrument called a seismograph. Activity B: Distance to the epicenter. Gizmo earthquake recording station answer key. Introduction: An earthquake releases an enormous amount of energy, which passes through Earth's interior in the form of body waves. The Earthquake — Recording Station Gizmo™ simulates the seismic waves released by an earthquake. Observe: Click Play, and observe the P and S waves.
Turn on Show time probe. What is the Time difference (∆T) between the P and S waves? What symbol represents the epicenter? Earthquakes 1 – Recording Station GIZMO < ALL ANSWERS CO... - $10.
When seismic waves reach the seismograph, a graphical record, or seismogram, is produced. Customizable versions of all lesson materials. Earthquakes are usually caused by the sudden movement of rocks along a fault, or fracture, in Earth's crust. It helped me a lot to clear my final semester exams. Question: How can you determine how far you are from the center of an earthquake? What symbol represents the recording station? Earthquake proof homes gizmo answer key pdf. This assignment is worth 25 points. Measure the P and S wave time difference (∆T) on the seismogram at each distance, and record the values in the table on the left. What major cities are located near the San Andreas Fault?
Now is my chance to help others. To begin, look at the key on the bottom left side of the Gizmo. See example at right. 4579 documents uploaded. If so, what did it feel like? Which waves are faster? The most famous fault in the U. S. is the San Andreas Fault in California. Have you ever experienced an earthquake? Estimate the time difference (∆T), and then use your graph to find the distance to the epicenter. Gizmos earthquake 2 answers. Remember to go to and login. Draw a line to connect the points in order.
What happens when the seismic waves hit the recording station?. Click Play () and observe the seismic waves leaving the epicenter of the earthquake. Does not need to be exact. ) What is shown on the seismogram at this time? Activity B (continued from previous page). At what time did the S wave hit? Get the Gizmo ready: - Click Reset (). Measure: Wait until the seismogram is complete. Select the gizmo: Earthquake Recording Station and complete the questions below. Question: How are P and S waves shown on a seismogram? What does this graph show? The epicenter of the earthquake is the point on Earth's surface closest to the focus, or origin, of the earthquake.
Based on the pattern of waves on the seismogram, what did you experience during the earthquake? Prior Knowledge Questions (Do these BEFORE using the Gizmo. You even benefit from summaries made a couple of years ago. Check that the Distance from the station to the center of earthquake is 860 km. Preview 1 out of 7 pages. Place the left (green) probe on the first P wave, and the right (blue) probe on the first S wave.
Apply: Suppose a recording station was located 500 km from the epicenter. Subscribers Get: - Access to community lesson materials. Draw conclusions: How does the time difference (∆T) between the first P wave and the first S wave relate to the distance to the epicenter? What would this earthquake feel like? I find Docmerit to be authentic, easy to use and a community with quality notes and study tips. Generating Your Document. Subscriber Access Only. Practice: On each of the seismograms below, label the first P wave and the first S wave. Gather data: Place the recording station at each of the following distances to the epicenter. University Of Arizona. Docmerit is a great platform to get and share study resources, especially the resource contributed by past students and who have done similar courses. Make a graph: Plot your data on the graph to the right of the data table. Access to ALL Gizmo lesson materials, including answer keys. Look at the upper right corner of the seismogram.
Earthquakes 2 - Determination of Epicenter. Predict: How do you think the time difference between the first P wave and the first S wave will change as the distance to the epicenter increases? There are two types of body waves:P waves (primary waves) and S waves (secondary waves). What will be the time difference (∆T) between the first P wave and the first S wave? Look at the Recording station detector on the upper left side of the Gizmo. Student Exploration: Earthquake — Recording Station.
Docmerit is super useful, because you study and make money at the same time! Place the recording station 300 km from the epicenter. Locate the epicenter of an earthquake by analyzing seismic data from three recording stations. Check your answer using the Gizmo. Explore: Click Reset, and drag the recording station closer to the epicenter.
