Stressed Out Rocks
Between 2 Plates
It's not my fault, it's yours!
Seismo' Shmeismo
Tectonics and Landforms
100
Vibrations in the ground that are produced during an earthquake.
Seismic Waves
100
Plate boundary where tectonic plates move away from each other
Divergent Boundary
100
A break in the rock
A fault
100
The point on Earth's surface directly above the origin of the seismic waves
Epicenter
100
A large ocean wave that is caused by the water that is displaced, or moved, during an earthquake.
Tsunami
200
If rocks were being pulled apart, they are experiencing this kind of stress.
Tension
200
Plate boundary that occurs when 2 different kinds of earth's crust collide
Oceanic-Continental convergent plate boundary
200
Identify the fault in this drawing:
Reverse Fault
200
The device used to measure earthquake movement
Seismometer
200
The landforms seen at continental-continental convergent plate boundaries
Super Tall Mountains
300
Type of stress that causes strike-slip faults
Shear stress
300
New oceanic crust is made here all the time
Mid-Ocean Ridge
300
When the footwall goes up, then you have this kind of fault
Normal Fault
300
The second set of seismic waves to be felt when experiencing an earthquake.
Secondary Waves (S-Waves)
300
When one piece of crust is pushed deep into the hot mantle
Subduction
400
This kind of plate boundary experiences tension stress
divergent plate boundary
400
The major fault system in Southern California is called this
The San Andreas Fault System
400
The block below the fault surface is called the
Footwall
400
The number of seismometer stations needed to pinpoint three or more potential locations of an earthquake's epicenter
1
400
The name given to when all of the world's landmasses make up one big landscape
Supercontinent
500
The kind of stress the rocks experience in SUPER CRAZY TALL mountain ranges (like the Himalayas)
Compression
500
What physical process is responsible for bringing hot, buoyant melted plate material UP to the planet's surface?
Convection
500
The amount of distance a fault moved during an earthquake
Displacement
500
Slowest type of seismic wave that causes the most destruction
Surface Waves
500
If I am in the field and can ONLY find reverse faults, then what can I determine about the overall geology of my field site?
Rocks are only experiencing compressional stress
