Earths Interior
The four layers of the Earth
Crust, Mantel, Inner Core, Outer Core
The theory that plates are moving is called
Continental Drift
Convergent plate boundaries move in this direction
Together
Divergent plate boundaries move in this direction
apart
Transform plate boundaries move in this direction
Past one another
The outer core is made up of these two elements
Iron and Nickel
This is created when oceanic plates move apart from one another
Mid-Ocean Ridge
The area of a convergent plate boundary that moves below another is called what
Subduction Zone
This is created when two plate move apart from one another under the ocean
Mid-ocean ridge
This driving force pushes the tectonic plates
Convection Currents
These three pieces of evidence support the Theory of Continental Drift
Shape of the continents fitting together
Fossils of the same plants and animals found on different continents
Rock samples (mountains) found on different continents
This type of plate boundary creates mountains
Continental Continental Convergent
This substance rises from the Earth's interior to fill the gap between oceanic divergent plate boundaries
Magma
The deeper you go into the Earth, these three things increase
Temperature, Pressure, Depth
This is used to measure plate movements
This type of plate boundaries creates volcanoes
Continental Oceanic Convergent
Rift Valleys
We have explored this deep into the Earth's interior
The Russian Borehole is 12 Kilometers (7.6 miles)
This scientist created maps of the ocean floor and discovered the Mid-Atlantic Ridge, proving the Theory of Continental Drift
Marie Tharp
This, along with a volcanic arc, is a feature produced when an oceanic plate subducts under a continental plate
A trench
Mid-ocean ridges create this type of rock
