• the speed and direction of seismic waves

• the location of an earthquake's focus

A level 1-3 on the Richter Scale is considered what type of earthquake?

• a major earthquake

• a small earthquake

• another name for seismic gap

Why do earthquakes usually occur at plate boundaries?

• The rock on the edges of tectonic plates is soft and gives in easily to various pressures

• Rock in environments near tectonic plate boundaries experience great stress

• The boundaries between tectonic plates have been seismically active for millions of years
