Most earthquakes occur here at active plate boundaries located where?
Where are the middle of oceans or the edges of continents?
Where is the energy released during an earthquake the strongest?
What is the epicenter?
Which seismic wave is second fastest and only travels through solids?
What are secondary waves?
Which seismic waves are the fastest?
What are primary waves?
What is it called when pressure is applied to a rock- that eventually may break the rock?
What is deformation?
This happens at convergent plate boundaries to cause deeper earthquakes.
What is subduction of one plate under another.
What are the 3 kinds of seismic waves?
What are primary waves (P waves), secondary waves (S waves), and surface waves?
True or False:
Surface waves can travel through solids, liquids, and gases.
What is FALSE! (Solids only!)
Which seismic wave is the slowest but the most destructive?
What are surface waves?
What is a break in Earth's surface where one block of rock moves toward, away, or past another block of rock?
What is a fault?
Earthquakes of which types of depths usually occur when continents collide?
What are earthquakes of varying (different) depths?
Which seismic waves can travel through solids, liquids, and gases?
What are primary waves?
Who are scientists that study earthquakes?
Who are seismologists?
True or False: Seismic waves all travel the same speed.
What is FALSE! (They travel in different speeds, depending on the materials they travel through.)
What are the 3 types of faults?
What are normal, reverse, and slip-strike?
Where are shallow earthquakes more common?
What are at divergent plate boundaries where plates are separating?
Which earthquake scale measures magnitude based on the seismic waves.
What is the Richter magnitude scale?
Which earthquake scale measures the amount of energy released by an earthquake?
What is the Moment Magnitude Scale?
