A body of rock affected by tensile stress will likely undergo ____________.

It is possible for offset along an oblique-slip fault to have both ____________ components.

A hot body of rock is more likely to exhibit ____________ than is a cold body of rock.

On a geologic map,if the contacts between sedimentary rock units form a bull's eye pattern of concentric circles,with the youngest unit in the center,the underlying structure is a(n)____________.

Mountain ranges are associated with modern and ancient convergent plate boundaries,but do not form in association with either divergent or transform plate boundaries.

A body of rock under high pressure is more likely to exhibit ____________ than is a body of rock at low pressure.

In a ____________ fault,the fault plane is greater than 30° from horizontal and the hanging-wall block moves upward relative to the footwall block.

A body of rock affected by compressive stress will likely undergo ____________.

The outer portion of a craton,where deformed rocks are covered by sediments,is termed the ____________.

Mt.Everest,the tallest mountain in the world,is located on the continent of ____________.

Regions of continents that have not been subjected to orogeny during the past one billion years are termed ____________.

In a ____________ fault,the fault plane is nonvertical and the hanging-wall block moves downward relative to the footwall block.

On a geologic map,if the contacts between sedimentary rock units form a bull's eye pattern of concentric circles,with the oldest unit in the center,the underlying structure is a(n)____________.

A fold shaped like an upside-down bowl is a(n)____________.

Within a cratonic platform,sedimentary rocks always have a horizontal orientation.

Most fault surfaces,like joints,are roughly planar in orientation.

The balance between the weight of a mountain range and the buoyancy provided by the underlying mantle is termed ____________.

Tectonic foliation,such as elongation of quartz grains,always occurs parallel to the original bedding plane of a body of rock.
