Plate Boundaries
Crustal Change
100
This plate is the largest on Earth and is where the Hawaii hot spot is located
What is the Pacific plate?
100
These seismic waves travel through both solids and liquids.
What are P-waves?
100
New York was closest to this latitude 300 million years ago.
What is the equator?
100
This is the site of a divergent plate boundary on Earth's surface.
What is a mid-ocean ridge or a rift valley?
100
This is the name of the supercontinent that existed 300 million years ago.
What is Pangaea?
200
These features form where continental crust converges with oceanic crust.
What are trenches or mountains or volcanoes?
200
These seismic waves travel fastest.
What are P-waves?
200
According to the theory of plate tectonics, the asthenosphere moves underneath this.
What is the lithosphere or the crust?
200
This is the type of plate boundary that exists between Africa and South America.
What is divergent?
200
These rock layers (strata) show the least evidence of crustal change.
What are horizontal strata or layers?
300
This feature is where you might find evidence of a rising convection current.
What is a mid-ocean ridge or volcano or hot spot?
300
These are cracks in the crust along which earthquakes occur.
What are faults?
300
This process is represented by the arrows in the diagram where magma circulates slowly and causes the plates above it to move.
What are convection currents or convection?
300
This is the type of plate boundary that exists between India and the rest of Asia.
What is convergent?
300
This is one piece of evidence that supports the theory of continental drift.
What are continent puzzle pieces or matching fossils on widely separated continents or matching rock layers on widely separated continents or differing climates from that of today?
400
These two things are often found in the same locations as volcanoes.
What are earthquakes and mountains?
400
Earthquakes tend to happen along this convergent plate boundary because of this process.
What is subduction?
400
This is one example of a location on Earth's surface where you would find evidence of a rising convection current.
What are hot spots or mid-ocean ridges or rift valleys?
400
This is the type of plate boundary that exists in California along the San Andreas fault.
What is transform?
400
This process is responsible for forming the hills in the diagram.
What is faulting?
500
This volcano in Hawaii is considered a composite cone because it alternates between explosive and nonexplosive eruptions.
What is Kilauea?
500
This type of crustal movement caused the displacement of the road in the first picture.
What is a transform fault or transform boundary?
500
This is the direction that the Pacific plate is moving.
What is northwest?
500
This type of plate boundary exists at the Peru-Chile trench.
What is convergent?
500
This is one of two pieces of evidence that the seafloor is spreading at a mid-ocean ridge.
What are the ages of the rock increase as you go farther from the ridge or the magnetism of the rock reverses polarity every so often across the ocean floor and the two sides of the ridge match?
