Convergent Boundaries
Convergent boundaries occur where two plates do this.
What is move toward each other?
This outermost solid layer includes both the crust and the uppermost mantle.
What is the lithosphere?
The theory of plate tectonics explains the movement of these.
What are tectonic plates?
The most famous transform boundary in the U.S. is this fault in California.
What is the San Andreas Fault?
Divergent boundaries cause new crust to form through this process.
What is seafloor spreading?
When an oceanic plate meets a continental plate, this dense plate subducts.
What is the oceanic plate?
The liquid layer responsible for Earth's magnetic field is found here.
What is the outer core?
This scientist proposed the idea of continental drift.
Who was Alfred Wegener?
Transform boundaries primarily cause this type of natural disaster.
What are earthquakes?
This type of rock is formed at divergent boundaries.
What is Igneous Rock?
When Oceanic Crust and Continental Crust converge, this crust subducts, or sinks.
What is the Oceanic Crust?
This solid but slowly flowing layer lies below the lithosphere.
What is the asthenosphere?
The movement of plates is driven by convection currents in this layer.
What is the mantle?
The movement along transform boundaries is measured using these instruments.
What are seismographs?
This type of force occurs when two tectonic plates move apart.
What is tension force?
The Appalachian and Himalayan Mountains are these type of mountains.
What are folded mountains?
The Earth’s densest layer, made mostly of iron and nickel.
What is the inner core?
These are formed as Oceanic Crust moves over a Mantle Hotspot.
What are Island Chains?
This type of fault occurs at Transform Boundaries.
What is a Strike-Slip Fault?
Newer rock is found here with respect to a Divergent Boundary.
What is closer?
These are the three types of convergent boundaries.
What are Oceanic-Oceanic, Oceanic-Crustal, and Crustal-Crustal?
The largest layer of the Earth, responsible for tectonic activity.
What is the Mantle?
This supercontinent existed about 300 million years ago before breaking apart.
What is Pangaea?
The separation between P and S Waves can tell you this about the Epicenter of an earthquake.
What is the distance?
These are formed when two Oceanic Plates move apart.
What are mid-ocean ridges?
