Exam 10: Deformation,Mountain Building,and Earth's Crust

The type of strain which occurs depends not only on the kind of stress applied,but also on what?

What is the dip of an inclined layer of rock?

The zone of rubble found along a fracture that has had movement on both sides is called

A fault with both dip-slip and strike-slip movement is classified as a(n)____________________-____________________ fault.

Because movement along a strike-slip fault is just horizontal,quakes along these faults are small and do not do much damage.

Divergent plate boundaries are responsible for most orogenesis.

If the mantle transmits S-waves,then how can it behave like a liquid,as implied by the principle of isostasy?

Sedimentary rocks that are now tilted were deposited ____________________.

In what type of fault does the hanging wall move up relative to the footwall at an angle of less than 45 degrees?

A simple bend or flexure,in an otherwise horizontal rock layer,is called a(n)____________________.

What role do geologists play in engineering large structures like bridges and power plants?

The most active orogenic belts today are the Alpine-Himalayan belt and the circum-Pacific belt.

What is the difference between brittle and ductile rocks?

Rocks that are tilted were deposited ____.

The forces that produce block-faulted mountains,such as the Basin and Range Province of the Western United States,are

What are some geologic processes which accompany orogenesis at oceanic-oceanic plate boundaries?

Movement along the San Andreas is ____.

Small accreted lithospheric blocks of foreign origin that differ completely from the rocks in surrounding regions are called ____________________.

On a geologic map the number adjacent to the strike and dip symbol is

A(n)____________________ divides a fold into two halves.
