- 2. Multiple ChoiceWhat are the fastest body waves?P wavesT wavesS wavesQ waves
- 3. Multiple ChoiceEarthquakes generally occur at plate boundaries, wherestress on rocks is greatestthe most rock is foundstress on rocks is lowmagnetic pull is greatest
- 4. Multiple ChoiceAt what location does the first motion of an earthquake occurthe focusthe seismic gapthe mantlethe epicenter
- 5. Multiple ChoiceA foreshock isa major earthquakea small earthquakeanother name for seismic gapa precusor to a tsunami
- 6. Multiple ChoiceWhy do earthquakes usually occur at plate boundaries?The rock on the edges of tectonic plates is soft and gives in easily to various pressuresRock in environments near tectonic plate boundaries experience great stressThe boundaries between tectonic plates have been seismically active for millions of yearsRockin environments near tectonic p late boundaries experience little stress
