Tectonic Processes Flashcards
What is compression?
Bending of rocks until they fracture and move suddenly long fault lines
What is compression most obvious?
At convergent plate boundaries and subduction zones
Where is an example of compression?
Kashmir 2005
What kind of earthquakes occur from compression force?
High magnitude earthquakes
What is tension?
Stretches the crust leading to faulting and rifting
What is rifting?
Blocks of crust slip Downwards
What kind of earthquakes does the movement of rifting with tension force cause?
Shallow earthquakes
What plate boundaries is tension associated with?
Divergent
What is shearing?
Strike slip fault
What plate boundaries is shearing most commonly at?
Divergent
What kind of earthquake does a strike slip fault and shearing cause?
Movement is erratic and sudden and produces violent quakes
What were the tectonic processes in Haiti?
Conservative plate boundary of the North American and Caribbean plates
Strike slip fault and compression
What were the tectonics of the Kashmir earthquake?
Indo-Australian and Eurasian continent collision
Forming fold mountains (Himalayas)
What are the three tectonic forces?
Compression
Tension
Shearing
What are the three different types of faults?
Normal dip-slip fault
Reverse dip-slip fault
Strike slip fault
