the rocks are being pulled in opposite directions
How does tensional stress deform a body of rock?
Fault-block Mountains
In what type of mountains are grabens most commonly found?
Volcanic mountains (hotspots), upwarped mountains, and fault-block mountains
List the 3 types of mountains that can form far from a plate boundary?
Mountains
Orogenesis refers to those processes that produce
dome
a circular feature produced by unwarping in rocks
strike-slip fault
a fracture with horizontal displacement parallel to its surface trend is called a
Plateau
an area of relatively level high ground.
Brittle deformation
an object fractures because it's strength point was reached, rocks near the surface ( glass objects, wooden objects, our bones)
Basin
downwarped structures that have roughly circular shape
compressional stress
folding is the result of
Graben
german word for ditch
time, rock type, and temperature
what affects how rock deforms
volcanic mountains
what type of mountains form at convergent boundaries where two oceanic plates meet?
normal faults
what types of faults are commonly associated with fault-block mountains?
volcanic, folded, and thrust fault mountains
which mountains are associated with convergetn margins
elastic, ductile, and brittle deformation
What are the different types of rock deformation
Antinclines and synclines
What are the two most common folds
Ductile deformation
changes the shape and size of an object without fracturing it. (clay, bee's wax,caramel candy)
higher
compared to the elevation of a thin piece of continental crust in isostatic balance, the highest elevation of a thick piece of crust will be
Accretion
the collision and joining of crustal fragments to a continent
hanging wall
the rock surface above a fault is called
strike-slip fault
the san andreas fault is a..
