Answer:
1. Earthquakes generate two main types of seismic, or shock, waves: body waves and surface waves. Body waves travel through the interior of the earth. The fastest of these are primary, or "P," waves. These compressional waves move faster in dense rock and slower in fluids.
2. Earthquake detection. A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram.
3. Magnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.
