(20 cards)
Where do ENDOGENIC PROCESSES happen?
in Earth’s interior
What is TOPOGRAPHY?
the study of the shape and features of land surfaces
What is GEOMORPHOLOGY about?
explaining landforms’
- origin
- shape
- spatial distribution
- development
What is a RELIEF?
vertical elevation in terrain
What are examples of HIGH RELIEF?
- mountains
- plateaus
What are examples of LOW RELIEF?
- plains
- valleys
What are the three PRINCIPAL TECTONIC FORCES?
- compressional
- tensional
- shearing
- Vertical
- Pushes towards each other
- Forms rocky mountains
compressional
What do compressional forces cause?
- folding in ductile materials
- faulting in rigid materials
What is a FAULT?
slippage of rocks along a fractured surface
What happens in a REVERSE FAULT?
rocks slide towards each other and go in different diagonal ways
What happens in a THRUST FAULT? (OVERTHRUST)
one rock overlaps and the other subducts
- Vertical
- Forces move opposite each other
tensional
What do tensional forces cause?
normal faults
What is a NORMAL FAULT?
- similar to reverse
- rocks move away from each other
Raised rock between two faults
horst
Lowered rock between two faults
graben
- Horizontal & lateral
- Forces move opposite each other
shearing
What do shearing forces cause?
strike-slip faults
What is an example of a strike-slip fault?
San Andreas fault
