Continental Drift
The man who first proposed Continental Drift.
Who is Alfred Wegener?
This refers to the addition of new rock the the floor of the ocean
What is sea-floor spreading?
This is the point on the crust above the focus in an earthquake.
What is the epicenter?
The outer layer of the Earth.
What is the crust?
A boundary in which the plates are moving towards each other.
What is convergent fault?
The force of gravity causing subduction.
What is slab pull?
This describes the point in the mantle an earthquake occurs
Alfred's name for the land before.
What is Pangaea?
The middle layer of the earth.
What is the mantle?
A boundary where the plates are moving away from each other.
What is a divergent fault?
The force exerted by magma rising and cooling between two plates.
What is Ridge Push?
This device measures seismic activity.
What is a seismometer?
Wegener's main piece of evidence for continental drift
What is the jigsaw fit?
The denser type of crust.
What is oceanic plates?
This type of convergent boundary leads to broad mountain ranges and shallow Earthquakes.
What is a continental-continental fault?
This piece of evidence for continental drift refers to the direction of Iron in the new formed rock.
What is magnetic evidence?
These waves travel through the Earth.
What is body waves?
This piece of evidence refers to the patterns of rock formations in landforms.
What is matching mountains?
The liquid layer that the crust floats on.
What is Asthenosphere?
This convergent fault leads to volcanic island chains.
What is an oceanic-oceanic fault?
This piece of evidence refers to the distribution of ancient animals around the world.
What is fossil evidence?
These waves travel only through the liquid layers of the Earth.
What are S-waves?
