The San Andreas fault is this type of boundary.
What is transform?
This is found directly below the epicenter.
What is the focus?
This type of plate boundary formed the Himalayas.
What is a convergent boundary?
Mt. St Helens is this type of volcano.
What is a composite cone volcano or stratovolcano?
P-waves are this type of wave. (longitudinal or transverse)
What are longitudinal (compressional) waves?
This is the reason why Yellowstone is geologically active.
What is a hot spot?
This type of wave is the most destructive.
What is a surface wave?
This 12 step scale is not very accurate due to different building styles throughout the world.
What is the (Mercalli) Intensity Scale?
Explosive eruptions results from this type of magma.
What is viscous?
S-waves are this type of wave. (longitudinal or transverse)
What are transverse waves?
This person wrote “The Origin of Continents and Oceans” where he proposed continental drift theory.
Who is Alfred Wegener?
This wave has the highest speed.
What is a p-wave?
Besides being a divergent boundary, the mid Atlantic ridge also has smaller types of this boundary.
What are transform boundaries?
The way a volcano erupts depends on these 3 things.
What are composition, temperature, and amount of dissolved gases?
The Red Sea is a result of this type of plate boundary.
What is a divergent boundary?
Scientists use this method to calculate the distance to the epicenter of an earthquake.
What is the "time interval" (time lag) between the P and S wave?
The Circum-Pacific rim is also called this.
This is the name of the opening of the conduit at the surface.
What is a vent?
This is how the thickness and age of oceanic crust change as you move further and further from the mid-ocean ridge.
What is thicker and older?
This mechanism drives the movements of tectonic plates.
What is (plate-mantle) convection currents?
An earthquake with a magnitude 8.5 has this many times increase in wave amplitude than a 5.5 magnitude earthquake.
What is 1,000x?
Because this type of plate is denser than a continental plate, it will subduct below.
What is an oceanic plate (crust)?
These are the three types of volcanoes. Hawaii is this type of volcano.
What are shield, composite cone (stratovolcano), and cinder cone volcanoes?
This is what SLR stands for.
What is Satellite Laser Ranging?
