Which feature is modeled in the diagram?
A convergent boundary is formed.
Two plates are forming a divergent boundary.
Continental plates are sliding past each other.
Several mid-ocean ridges are formed on Earth’s surface.
Which phrase describes this plate boundary?
does not occur in oceans
may form rift valleys
is a type of convergent boundary
is a region where earthquakes occur
In which two places do divergent boundaries occur?
land and oceans
oceans and volcanoes
volcanoes and lower mantle
lower mantle and land
Use the earthquake distribution map and what you know about boundaries to answer the question.
Studies have shown that there is a relationship between the type and location of boundaries and the distribution and depth of earthquakes along or near these boundaries. Many earthquakes, shown in the map as wide bands, occur along convergent areas. These areas experience varying depths of earthquakes.
Where would oceanic-oceanic convergence most likely occur?
Nazca plate converging with the South America plate, forming the Andes mountains
Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean
Juan de Fuca converging with the North American plate, forming the Cascade mountains
North America Plate converging with the Eurasian Plate, forming a mid-ocean ridge
Sometimes earthquakes occur at a boundary between the Indian and Eurasian Plates. The collisions of these two continental plates formed the Himalayan mountain range.
Based on this information, which type of boundary exists between the Indian and Eurasian Plates?
continental-continental convergent
continental-continental divergent
oceanic-continental divergent
oceanic-continental convergent
Occasionally earthquakes occur as a result of collisions along oceanic-continental convergent boundaries. Where do these earthquakes most likely occur?
on land but close to oceans
inland, far from the coast
in the middle of the oceans
anywhere there are mountains
During the process of mountain building, earthquakes sometimes occur along continental-continental convergent boundaries. Which statement best describes the motion of the plates along these boundaries that causes the earthquakes?
The plates push apart from each other with no subduction.
Subduction occurs with the less-dense plate sinking below the other plate.
Subduction occurs with the more-dense plate sinking below the other plate.
The plates smash together with no subduction.
Use the earthquake distribution map to answer the question.
Scientists have found that shallow and narrow bands of earthquakes occur at divergent boundaries.
Where would a divergent boundary occur?
between the South American and African Plates
between the Australian and Eurasian Plates
between the Eurasian and African Plates
between the Nazca and South American Plates
Which describes the boundary where earthquake activity occurs along rift valleys?
divergent boundary in the ocean
divergent boundary on land
convergent boundary in the ocean
convergent boundary on land
Which best explains why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys?
Plates bump as they slip past each other at convergent boundaries.
Plates get stuck as they move past each other at convergent boundaries.
Crust gets cracked and forms faults as plates collide along divergent plate boundaries.
Faults form because crust gets cracked when plates move apart along divergent plate boundaries.
Where would you most likely find transform boundaries on an earthquake distribution map?
where earthquakes are shallow and weak
where earthquakes are shallow and powerful
where earthquakes are deep and weak
where earthquakes are deep and powerful
Many earthquakes occur near mid-ocean ridges but do not destroy or form new crust. Instead, plates slip past each other. Which kind of boundary is found at these earthquake locations?
transform boundary between two ocean plates
transform boundary between two continental plates
convergent boundary between two ocean plates
convergent boundary between two continental plates
Many more earthquakes occur along the San Andreas Fault in California than in other parts of the United States. Scientists claim that these earthquakes are caused by activity along a transform plate boundary.
Which evidence would best support this claim?
Subduction causes new crust to form.
Subduction causes old crust to be destroyed.
Plates slip past each other at the boundary.
Plates collide with each other at the boundary.
