Get my drift?
This the name of the man who created the theory of continental drift.
Who is "Alfred Wegener"?
This is one of the most famous faults in California, and perhaps the US.
What is the "San Andreas fault"?
Name the three types of Stress
What is Shearing, Tension and Compression
This occurs at all convergent plate boundaries and is the reason the mantle and crust "recycle" themselves.
What is "subduction"?
The opening of the volcano
Vent
This is the name for the large super-continent that eventually spread apart, providing evidence for continental drift.
What is "Pangaea"?
This type of plate boundary is commonly found in the middle of oceans, for example, the Atlantic.Two plates move away from each other - usually ocean crust
What is "divergent"?
This type of fault the rocks on either side of the fault slip past each other with little up-or-down motion
What is a "strike-slip fault"?
A type of stress that pushes a mass of rock in two opposite directions by scraping against one another?
What is "Shearing"
Out of continental and oceanic plates, this one is more dense.
What is "oceanic"?
Where the magma is stored in the volcano
Magma Chamber
After this event, the evidence for continental drift was strong enough for scientists to propose the theory of plate tectonics.
What is "World War II"?
These plates collide with one another.
What is "convergent boundaries"
•The fault is at an angle so one block is pushed up the face of the other.
Caused by Compression
What is a "reverse fault"?
What type of stress pulls on the crust.
Tension
using sound waves to determine depths and sizes of objects
What is "Sonar"?
Volcano with gently sloping sides. Mostly fluid magma eruption.
Shield Volcano
The idea that the world’s land masses are slowly moving over time
What is Continental Drift
Two oceanic crusts colliding
What is "ocean to ocean convergent"?
•The fault is at an angle so one block slides down the face of the other.
Caused by Tension
What is "Normal Fault"
This event commonly occurs along fault lines.
What is "earthquakes"?
This occurs at divergent boundaries when mid-ocean ridges have new crust formed pushing the ocean floor apart from each other.
Sea Floor Spreading
A volcanic crater from a collapsed magma chamber (where a volcano erupted)
Caldera
These ancient relics of plants and animals provided evidence for both continental drift and evolution.
What are "fossils"?
You encounter a fault with a hanging wall, this is the type of plate boundary you're on. Two plates scraping past each other
What is "transform"?
Two types of Walls
Hanging and Footwall
Squeezes rock until it folds or breaks is which type of Stress
What is "compression"
Liquid molten rock that has reached the earth’s surface. Solid rock when cooled.
Lava
Area where heat rises in the mantle is called
Hot Spots
What kind of evidence was the continents appear to fit together like pieces of a puzzle
What is Geometric Evidence
Which boundary creates Mid-Ocean ridges, Seafloor spreading and Earthquakes
Divergent
The point on the surface directly above the focus
Epicenter
The study of
volcanoes, magma,
lava, and related
topics
Volcanology
The channel where magma travels up the volcano.
Conduit
Fast moving current of hot gas and rock, sometimes at 100 mphs
Pyroclastic Flow
What kind of evidence of Alfred's was deposits of coal prove that tropical plants used to grow in cold areas like Antarctica
Climate Evidence
Which Convergent boundaries creates Volcanoes,Trenches,Earthquakes and Subduction Zones
Land vs Land
Land vs Ocean
Ocean vs Ocean
Land vs Ocean
The point beneath the Earth’s surface where the fault first breaks
Focus
Molten rock / hot fluid in the mantle
(below the earth’s
crust)
Magma
It is a cone-shaped mountain volcano, many layers of lava and ash
Stratovolcano
75 % of the world's volcanoes are located on the.......
