Wow, Mountains!
The North American & African Plates colliding created this mountain range
The Appalachian Mountains
The place where two plates are moving apart is called this (not a type of boundary)
a ridge
The Mid Atlantic Ridge is a _________ mountain range.
volcanic
This boundary is created when 2 plates slide past each other
Transform
Most mountains are formed by two plates doing this, & creating this kind of boundary.
two plates creating a convergent boundary
These are the two primary changes that occur the deeper you go under the surface of a mountain
Increasing temperature & increasing pressure
This was Alfred Wegener's theory that the continents were once connected as Pangaea and then separated and moved
Continental drift
The solid rock that lies under loose material within the crust of earth. (vocab word)
Bedrock
This boundary is created when 2 plates collide
Convergent
Elevation above sea level is calculated by these 2 rates
Erosion Rates & Uplift Rates
These mountains are considered a collisional mountain range (in the US)
Appalachians
This is something in the middle of the Atlantic ocean, created by 2 divergent plates.
The Mid-Atlantic Ridge
This boundary is created when 2 plates divide
Divergent
This is the difference between magma and lava
Magma is below the surface while lava is above
A representation of how much the land is being pushed up from below by plate movements.
Uplift rates
A representation of how much an area of land is worn down by all the erosive processes together
Erosion Rate
This is the dense basalt rock found under the ocean (not a rock)
Oceanic Crust
These rocks are formed when magma cools and solidifies.
Igneous rocks
The process of wearing or being worn by long exposure to the atmosphere
Weathering
This is how we can explain marine fossils ending up at the top of Mt. Everest (I'm looking for 3 steps)
Plate tectonics, the sea draining, the seafloor is uplifted
A Volcano
A collision between Siberian and East European Plates created this mountain range (NOT in the US)
The Ural Mountains
This is what it's called when the sedimentary rock near the surface gradually TRANSFORMS into metamorphic rock.
Rock Transformation
The layers of the earth, from top to bottom
Crust
Mantle
Outer core
Inner core
A geological process where new oceanic crust is formed at Mid Ocean Ridges, pushing older crust away, contributing to the movement of continents.
Seafloor Spreading
