Plate Tectonics
Where do most Earthquakes and Volcanoes form?
Plate Boundaries
List the layers of earth from innermost layer to outermost
inner core
outer core
mantle
crust
What is the theory that Earth's Plates are slowly moving over time?
Continental Drift
What is the name of the supercontinent we discussed?
Pangea
Which plate will ALWAYS subduct at a Land v Ocean Convergent Boundary?
Ocean
Which boundaries are constructive?
Divergent
Which layer is liquid?
Outer core
What is the theory that the ocean floor is growing wider over time?
What is sea floor spreading?
Which piece of Evidence explains south America and Africa fitting together?
Geometric
What are the 3 Forces acting on a plate?
In any order
1. Convection
2. Pressure
3. Gravity
Which boundaries are destructive?
Convergent
Mantle
What are two pieces of evidence that sea floor floor spreading is occurring?
1. Magnetic Striping
2. Age of Rocks / Rocks are same age at same distance
Which piece of evidence explains evidence of species found on continents separated by oceans?
Fossil
Which of the forces pushes magma up?
Pressure
What are caused by divergent plates in the middle of the ocean?
Mid-Ocean Ridges?
What layers make up the Lithosphere
List all 4 of the pieces of evidence to support Continental Drift.
In any order
1.Geometric
2. Climate
3. Fossil
4. Mountain
What was left by Glaciers that supports climate evidence?
Deep Deposits / changes in landscape from glaciers changing land
Desribe the Process of Convection.
Must Include:
1. Temp increasing and density decreasing causing rising.
2. Cooling causing density to increase and causing sinking
3. Process repeats like a conveyer belt/treadmill/ airport luggage.
What is responsible for the formation of Hawaii?
Hot Spots
Which layer causes the movement of plates?
Asthenosphere
What is the Mechanism of the Theory of Continental Drift?
Seafloor spreading
What was found in Antarctica that supports climate evidence?
Coal
When we discussed the formation of Florida, what two things ocurred for FLorida to form.
1. Erosion from water in the Mountains
2. Build up of Sediment (carried by water)
Note: water is BOTH Constructive and Destructive
