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..
