Continental Drift
This is the name of the scientist who theorized 'continental drift'
What is a convergent boundary?
A volcanic mudflow
What is a lahar?
A body wave travels through this.
What is Earth's interior?
A volcano may form here, which is NOT at a plate boundary.
What is a hot spot?
The fit of these two continents led to the development of this theory
What are Africa and South America?
(Must have both to earn points!)
Two plates moving apart
What is a divergent boundary?
A flowing mass of ash, dust, debris, and hot air
What is a pyroclastic surge?
These waves cause the most destruction because they shake buildings and cause the ground to move.
What are surface waves?
Earthquakes can occur from plate boundary movement. They can also occur from this.
What are volcanoes?
Accepted answers: landslides, meteor impacts
(also acceptable: ancient climates, rock layers)
This sliding plate interaction is mostly associated with earthquakes, especially in California
Accepted answers: low viscosity, basaltic, Pahoehoe, flowy, thin, extremely hot
A type of body wave that is very fast and compressional.
What is a P wave?
Oceanic crust is more __________ than continental.
Accepted answers: thin, dense
The reason that the continental drift hypothesis was never turned into a theory.
An oceanic plate sliding underneath a continental plate is called this
What is subduction?
What is a composite (strato) volcano?
Earthquake damage is reported in these values, which are based off of witness's feedback.
What is intensity?
A mid ocean ridge is likely to be found at this type of plate boundary.
What is a divergent plate boundary?
Discovering the age of this was helpful in determining the modern theory of plate tectonics over continental drift.
Trenches and volcanic arcs are found along these plate boundaries.
What is a convergent boundary?
The smallest type of volcano, produces cinders during short explosive eruptions.
What is a cinder cone?
The theory that explains that rocks bend and snap back to their original shape during an earthquake.
What is the Elastic Rebound Theory?
The Pacific Ring of Fire is mainly this type of plate boundary, along with transform boundaries.
What are convergent plate boundaries?
