Anticline
What is Most commonly formed by the upfolding, or arching, of rock layers.
100
What is a joint
A fracture which has shown no sign of significant displacement.
100
Faults in which the movement is primarily parallel to the inclination, or dip, of the fault surface.
A dip slip fault is know as what?
100
What is Island Arcs
When two or more oceanic plates converge and one is subducted beneath the other.
100
what are mountain blocks
What is collision and merger of an island arc and continental block.
200
synclines
What is often found in association with anticline are downfolds,or troughs?

What is large strike slip faults.
Transform faults are known as

In the western United States, large scale normal faults are associated with which kind of structures?
200
What is Orogenesis
What is the type of process which involve the formation of the mountain belt.

When does collision happen?
What is it called when the oceanic lithosphere subducts beneath the continental margin.
300
Symmetrical
Depending on their orientation these basic folds are described as what?
300
What are strike slip faults
Mainly exhibit horizontal displacement parallel to the fault surface
300
Horsts
An elongated valley bounded by relatively uplifted structures are known as what?
300
What is convergent plate boundaries.
Most mountain building begins when at what boundary?
300
What is the continental crust.
The oceanic lithosphere is relatively dense and subducts under what crust?
400
monoclines
What are step like folds in otherwise horizontal sedimentary strata.
400
Southwestern California
The San Andreas fault cuts the continental lithosphere and accommodates the northward displacement of what state?
400
Graben
A central block that is bounded by normal faults and drops as the plate separates is known as what?
400

the formation of continental volcanic arc and related tectonic feature island of the conventional margin is known as?
400
What are mountain belts.
What is the result of crustal shortening and thickening produce what type of belt?
500
Dome
What is it called when a upwarping produces a circular or elongated structure?
500
Outermost crusts
Parallel orientations and are the best result of a failure in the rock unit which are located where?
500
Normal faults
What is it called when the hanging wall block moves down relative to the footwall block?
500
What is Island arcs and Andean types margins.
What are two types of mountain belts that the subduction of oceanic lithosphere creates?
500
what are mountain blocks?
What can develop as the collision and merger of an island arc with the continental block.
