Exam 10: Earthʹs Surface Relief Features

Whereas mountains occur on every continent,depressions (basins)only occur in Asia and Africa.

Small surface irregularities along a fault plane that prevent movement and are generally areas of high strain are termed

Warping produces bends in rocks that are _________those produced by folding.

The energy released by a magnitude 8 quake on the Richter scale is how many times greater than that of a magnitude 6 quake?

Extensive plains are found in North and South America,Asia,and Australia.

The six types of topographic regions are defined based on

The relatively young mountains along the western margins of the North America and South America plates are referred to as the

The Basin and Range Province of the interior western United States is a type of horst -and-graben topography.

Compressional stress along a fault resulting in rocks moving upward along the fault plane is an example of a

An active volcano is one that has erupted at least once in the last 25 years.

The measurement of land elevation relative to sea level is known as

The area at the surface directly above the subsurface location where seismic waves are initiated is termed the

The Appalachians formed as a result of the

Folded layers of rock can form a wavelike pattern of troughs and crests.The layers near the crest (i.e.the upward fold)form

Circular surface depressions usually found at or near the summit of a volcano are known as

Landscapes are grouped into orders of relief by scale,from continents and ocean basins to individual landforms.

The Richter scale replaced the moment magnitude (M)scale for measuring earthquake magnitude.

Prior to the invention of seismometers,damage to terrain and structures and severity of shaking were used to assess an earthquakes size.

The topography of Earthʹs surface has had relatively little influence on human activities and culture.

Which of the following is a cause of warping?
