Plate Tectonics
What is a plate boundary
The layer that we stand on
What is the crust
The innermost layer
What is the inner core
The first wave that is released after an earthquake
What is a P wave/ primary wave?
This is where earthquakes typically occur
What is along plate boundaries?
The type of plate boundary where two plates move together
What is convergent?
The largest layer
What is the mantle
The type of crust that is thicker and less dense
What is continental?
This wave moves faster
What are P waves?
This type of wave travels on Earth's surface
This plate boundary is where two plates are moving away from each other
What is divergent?
The type of crust that is thinner and denser
What is oceanic?
These occur in the mantle and drive plate movement
What are convection currents?
The layer that S waves cannot travel through
What is the outer core?
This plate boundary involves two plates sliding past each other and creates large shallow earthquakes
What is transform?
Continental-continental Convergence forms this
What is a mountain?
What is the Asthenosphere?
This layer is semi-liquid
What is the mantle?
This type of wave involves particles moving parallel to wave movement
What are longitudinal waves?
The landform that is created by a divergent plate boundary
What is a ridge?
These geological features are formed when an oceanic and continental crust converge
What is a volcano and a trench?
The layer that is made of the top of the mantle and the crust
What is the lithosphere
The materials that the outer core is composed of
This type of wave involves particle movement perpendicular to wave motion
What are transverse waves?
