Module 1: Moving Plates
Which of the following features is associated with oceanic hot spots?
A mantle plume
What plate boundary types are associated with subduction?
All three types of convergent boundaries
What type of plate boundary can result in a complex of folded and faulted mountains and the greatest overall crustal thickness?
Continental-continental convergence
What type of plate boundary creates new crust as the plates pull apart?
Divergent
What are the types of plate boundaries in plate tectonics?
Divergent, convergent, and transform
Which statement describes Pangaea?
During the middle of the Paleozoic, Earth's landmasses were converging to form Pangaea.
Which statement describes Earth's magnetic field?
Earth's magnetic field has reversed numerous times at irregular intervals.
Which evidence supports plate tectonic theory?
Fossils from India and fossils from the continents of the southern hemisphere matched.
Which location exemplifies a plate tectonic hot spot?
Hawaii
What term describes the rising and sinking of the lithosphere as material is added or removed?
Isostacy
What is the importance of the asthenosphere?
It is the plastic region of the Earth's interior that enables the crustal plates above to move.
In regards to the geologic time scale, which statement is supported?
More details are known about the more recent blocks of time than the earlier blocks.
Where is an example of an oceanic-oceanic convergent boundary?
Northern Japan
What type of plate boundary creates a volcanic island chain?
Oceanic-oceanic convergence
Which of the following is an example of a divergent boundary?
Red Sea
Where is an example of a transform plate boundary?
San Andreas Fault
Where is an example of a continental-continental plate boundary?
The Himalayas
Which tectonic plate is primarily basaltic, among the largest in area, and among the fastest-moving?
The Pacific Plate
Which statement describes future changes based upon current tectonic plate movements?
The distance between New York City and Paris, France, will increase.
Of the following, which location exemplifies the earliest developmental stage of a divergent boundary?
The location that exemplifies the earliest stage of a divergent boundary is the African Rift Valley. The African Rift Valley is a very young divergent boundary. The continental crust is beginning to crack and spread apart. The Red Sea, which is at a later stage, is sufficiently mature for seafloor spreading to have progressed to the point that the rift has been filled by seawater. The divergent boundary of the Atlantic Ocean exemplifies the oldest stage in the development of a divergent boundary. The Juan de Fuca Plate and North American Plate boundary is an oceanic-continental convergent boundary. Hawaii is an oceanic hot spot in the middle of the Pacific plate. These each display the characteristic patterns for the plate boundary types and features.
What mechanism is thought to cause tectonic plates to move?
Thermal convection in the mantle
What type of plate boundary is most likely to contain lateral or strike-slip faults?
Transform
Which statement describes mid-oceanic ridges?
Transform faults run perpendicular to the mid-oceanic ridge axis.
In which of the following locations is there an oceanic-continental convergent boundary?
Washington and Oregon
Which part of Earth's interior is liquid?
outer core
