Exam 9: Deformation, Mountain Building, and the Continents

How can you tell a dome from a basin?

The principle that Earth's crust is in floating equilibrium with the denser mantle below is known as ____________________.

What is meant when a fold is described as being recumbent?

An important means of continental accretion is plutonism.

Dip-slip faults include:

What is an orogeny? What does a theory of orogeny need to explain?

A(n)____________________ is a circular or oval fold in which the strata are warped downwardly in the center and the beds on the flanks are ____________________ in age than the strata in the interior.

Most orogenesis takes place on oceanic-oceanic convergent plate boundaries.

What happens if a rock is strained beyond its elastic limit?

Why is the study of deformation and deformed rock important?

Divergent plate boundaries are responsible for most orogenesis.

Continental crust is always thicker than oceanic crust.

What happens first when a stress is applied to a rock? What two things could happen if the stress continues to the next step?

What are terranes?

Strike-slip faults are caused by ____________________ forces.

What are the three types of stress,and how do they affect rocks?

The type of fold that forms traps for most of the world's produced petroleum is a(n)____________________.

A cliff formed as a consequence of vertical movement along a fault is a fault scarp.

A fault with both dip-slip and strike-slip movement is classified as a thrust fault.

Describe the plate tectonics processes and associated stresses that have led to the formation of the Himalayas,the world's largest mountain range?
