Answer | |
---|---|
Instruments At Earth's Surface Which Record Seismic Waves | Seismographs |
Tracing Of Earthquake Made On A Seismograph | Seismogram |
Scientists Who Study Seismic Waves | Seismologist |
How Does Energy Manifest From Earthquakes | From Seismic Waves Or By Shaking The Ground |
Where Do Earthquakes Occur? Example (Oceanic vs. Continental) | Plate Boundaries |
What Causes Earthquakes To Happen? | Deformation |
The Study Of Earthquakes | Seismology |
Waves Created By An Earthquake That Travel Through Earth | Seismic Waves |
The Two Ways That Earthquakes Deform Are... | Plastic, Elastic |
It Goes With The Flow, Has Little Potential Energy | Plastic |
Has A Lot Of Potential Energy That Can Be Devastating (when released) | Elastic |
This Scale Measures How Strong The Earthquke Is | Richter scale |
This Scale Is About The Damage It Creates And How Much It Costs (In DollarsTo Repair That Damage | Mercalli Scale |
Can I Forecast Accuratly Where An Earthquake Will Happen | NO, But You Can Guess By Guessing That An Earthquake Will Happen By One That Has Just Happened Recently |
Possibilities Of Technology To Be Put On Buildings To Make Them Safer | Shock absorburs, steal bridges/braces |
They Arrive Second, They Only Go Through Liquid, Second Fastest | S-Waves |
They Arrive First,They Are The Fastest, They Can Go Through Anything | P-Waves |
The Distance To The Epicenter, The Distance Between S Waves and P Waves | Lag-Time |
The Occurance In The Earth | Focus |
Directly On Top Of The Earth's Crust | Epicenter |
