HW 10
Within the United States, which area has the highest earthquake hazards?
West Coast
orogenesis refers to
a general term for a mountain-building episode that thickens continental crust.
What type of convergent boundary associated with orogeny is illustrated here?
continental plate-continental plate collision
The average elevation of the depth of the oceans is
-3800 m (-12,470 ft)
Africa is dominated by which topographic region?
Hills and low tablelands
The San Andreas system in California is an example of a
both a strike-slip and transform fault
A __________________ is a small, cone-shaped hill usually less than 450 m (1500 ft) formed from material that accumulates from moderately explosive volcanoes.
cinder cone
The nucleus of old crystalline rock in each of the principal continental masses is called a
continental shield, or craton
Circular surface depressions usually found at or near the summit of a volcano are known as
craters
Volcanic activity located away from plate boundaries is associated with
hot spots
The Zagros mountains of Iran is an example of
a zone of compression and folding
An earthquake is best described as
the sharp release of energy in Earth's crust that creates seismic waves
The magnitude of earthquakes is measured by the ________________ scale
moment magnitude
What type of convergent boundary associated with orogeny is illustrated here?
oceanic plate-oceanic plate collision
A large region identifiable by several topographic or geological traits is known as a
physiographic province.
A topographic region that is characterized by local relief of less than 100 m (325 ft.) is considered a
plain
Vertical elevation differences in a local landscape are referred to as
relief
When lateral shear causes horizontal movement along a fault plane, the resulting fault is called a
strike-slip fault
normal faults are associated with
tensional forces
What type of convergent boundary associated with orogeny is illustrated here?
Oceanic plate-continental plate collision
