Landforms
This caused Hawaii to form.
a hot spot
the San Andreas fault
an earthquake
a tsunami
What is a hot spot?
This is where the energy of an earthquake originates.
Plates moving together form this type of stress.
Compressional
Shear
Tension
What is compressional stress?
This is the purpose of studying natural disasters.
What is to predict and prepare for future events?
Human activities are the cause of most of this type of natural disaster.
What are wildfires?
Mount St. Helens formed when the Pacific and North American plates did this.
What is converged?
This plate boundary may produce a mountain.
What is a convergent plate boundary?
Stress can cause rocks to do these two things.
What is fold or break (fault)?
This type of natural hazard occurs when saturated soil moves down a slope due to gravity.
What is a landslide?
The "Ring of Fire" is known for high seismic activity and this type of natural disaster.
What is volcanic activity?
The Andes Mountains are found along the western coast of South America.
This type of plate boundary is responsible for this mountain range.
What is a convergent plate boundary?
This plate boundary may produce mid-ocean ridges.
What is a divergent plate boundary?
Tensional stress (tightening) results from this type of plate movement.
What is divergent plate movement (moving away)?
This may result when the energy that builds up at transform plate boundaries is released because the plates suddenly overcome the force of friction.
What are earthquakes?
Due to little warning this type of flood is the most dangerous.
What are flash floods?
The San Andres fault formed as a result of plates sliding past each other at this type of plate boundary.
What is a transform plate boundary?
This type of boundary often times results in an earthquake or fault.
What is a transform boundary?
This type of stress is caused by plates moving against each other at a transform boundary.
Compressional
Shear
Tensional
What is shear stress?
This natural disaster is caused by underwater disturbances such as earthquakes.
What is a tsunami?
This natural event can cause multiple hazards to form simultaneously.
What is a volcanic eruption?
The Mid Atlantic Ridge formed as a result of this type of plate movement.
What are diverging plates?
Which plate boundary could form a mountain chain of sedimentary rock?
divergent boundary of oceanic crust and continental crust
convergent boundary of two continental crusts
convergent boundary of oceanic crust and continental crust
divergent boundary between two oceanic crusts
What is the convergent boundary of two continental crusts?
When rocks are compressed they can fold instead of breaking. The downfold caused by compression is called.
What is a syncline?
This is the difference between a tropical storm and hurricane.
The region known as "Tornado Alley" is prone to tornadoes due to this happening.
What is warm air masses from the south and cold air masses from the north colliding?
