Plate tectonics
The name Wegener gave to the super-continent that existed 300 million years ago
What is Pangaea?
What is a convergent boundary?
These types of waves require a medium to move through
What are mechanical waves?
This boundary can create mountains
What are convergent boundaries?
The rigid part of the Earth including the crust and the upper mantle (makes up the plates of the Earth)
What is the lithosphere?
This constant motion causes plates to move
What are convection currents?
When two plates separate
What is a divergent boundary?
These types of waves do not require a medium to move through
What are electromagnetic waves?
These are created as a result of convergent boundaries
What are mountain ranges and volcanoes?
The thickest layer of the Earth
What is the mantle?
Breaks in the Earth's crust
What are fault lines or plate boundaries?
When two plates slide past each other
What is a transform boundary?
What is a disturbance?
The term for molten rock inside and outside of the Earth.
What is lava and magma?
Tectonic plates float/move on top of this layer
What is the asthenosphere?
Long underwater mountain ranges/chain formed by divergent boundaries
What are mid-ocean ridges?
What are earthquakes?
The direction of a disturbance in relation to a longitudinal wave's direction
This plate movement results in mid-ocean ridges and rift valleys
What is a divergent boundary?
____ waves can only travel through solids while ____ waves can travel through solids and liquids.
S-waves: travel through only solids
P-waves: travel through solids and liquids
This was how the Hawaiian Islands were formed
What is a hot spot?
The direction of a disturbance in relation to a transverse wave's direction
Perpendicular
This underwater land structure is created at convergent boundaries' subduction zones.
This became an indicator of the fact that the Earth's outer core is liquid.
S-waves cannot pass through liquid and are unable to pass through Earth's core.
