Boundaries
The three Types of Boundaries
Convergent, Divergent, Transform
What forms as a result of a normal fault?
Valleys and Fault block mountains
Name the three types of Volcanos
Shield, Cindercone, Stratocone (composite)
What process pushes oceanic plates back into the mantle?
Subduction
Earthquakes are measured in what?
Magnitude
Tension occurs are what kind of boundary
Divergent
What is the difference between the hanging wall and the foot wall?
Hanging wall moves, foot wall is stationary
Name the parts of a volcano
Central Vent (Pipe), Magma Chamber, Side Vents, Crater.
Plates are able to move because of this process in the Mantle
Convection Currents
An underwater earthquake will only cause a tsunami if there is
Ocean floor uplift
Where tectonic plates interact
What is the definition of a "Fault"
A break in the Earth
Hot spots generally form this type of volcano
Shield Volcano
Three pieces of evidence that support continental drift theory?
Climate data, Fern fossils, Coal deposits, reciprocal mountain formation
What kind of waves are produced during an Earthquake?
Seismic Waves
When stress is released at a boundary, this can occur
Earthquake~
Describe what occurs at a reverse fault.
Compressive forces of a convergent boundary push the hanging wall above the footwall.
What makes magma sticky?
High Silica content
The meeting of the Indian and Asian plates collided to form the Himalayan Mountain range. This is an example of what kind of plate interaction?
Convergent plate boundary pushing land up to build mountain landform.
What forms if magma under the water cools before it reaches the surface
Seamount.
What are three things that can occur at Divergent Plate boundaries?
Sea floor spreading, Normal Faults, Volcano formation
Which state is home to the largest fault in the US
(Bonus if you can name the fault)
California
(San Andreas Fault)
Hawaii was formed from what kind of phenomenon?
Hot Spots!
This scientist proposed the theory of Continental Drift
Alfred Wegener
In what order do Seismic waves travel?
Primary waves, Secondary waves, Surface waves
