Earthquake Gizmo Answer Key Overview
The answer key for the Earthquake Gizmo includes responses to various questions related to the simulation. Below is an organized breakdown of some common questions and their corresponding answers.
Understanding Seismic Waves
1. What are the three main types of seismic waves?
- Primary Waves (P-Waves): These are compressional waves that travel fastest through the Earth. They can move through solids and liquids.
- Secondary Waves (S-Waves): These are shear waves that can only move through solids. They travel slower than P-waves.
- Surface Waves: These waves travel along the Earth's surface and are responsible for most of the damage during an earthquake.
2. How do P-waves and S-waves differ?
- P-waves are faster and can travel through both solids and liquids, while S-waves are slower and only travel through solids.
Factors Influencing Earthquake Magnitude
1. What factors influence the magnitude of an earthquake?
- Depth of the Focus: Deeper earthquakes typically release less energy at the surface.
- Type of Fault: Different fault types (e.g., strike-slip, normal, reverse) produce varying magnitudes.
- Amount of Stress: Greater stress along a fault line can lead to more significant earthquakes.
2. How does the distance from the epicenter affect the intensity of shaking?
- The intensity of shaking decreases with distance from the epicenter. The ground motion is strongest near the epicenter and diminishes as you move farther away.
Visualizing Earthquake Data
1. What does a seismograph measure?
- A seismograph measures the motion of the ground caused by seismic waves. It records the amplitude and frequency of the waves, allowing scientists to analyze the earthquake's characteristics.
2. How is earthquake data used to determine the epicenter?
- By analyzing the arrival times of P-waves and S-waves at various seismograph stations, scientists can triangulate the epicenter's location.
