Theory of Plate Tectonics
The name of the pieces the lithosphere is broken up into.
What are plates?
The names of the two types of crusts.
What are oceanic and continental?
The location of convection currents.
What is the asthenosphere?
The name of the hypothesis that all the continents were once joined together in a single landmass and have since drifted apart
What is continental drift?
The name of Miss Ludwig's cat
What is Bucky?
The theory that states that pieces of earth's lithosphere are in slow, constant motion, driven by convection currents in the mantle
What is Plate tectonics
Layer of Earth where convection currents can be found
What is the asthenosphere?
Type of heat is transferred by the movement of currents within a fluid
What is convection?
The person responsible for the Theory of Continental Drift
Who is Alfred Wegener?
The idea that new material is added to the ocean floor causing it to grow.
What is sea-floor spreading?
This is what happens when oceanic crust and continental crust converge.
What is subduction?
The liquid layer of Earth
what is the outer core?
Heating and cooling of the fluid, changes in the fluid's density, and the force of gravity combine to set these in motion
What are convection currents?
The name of any trace of an ancient organism that has been preserved in rock
What is a fossil?
The type of rock is made above Earth's surface and does not contain fossils.
What are extrusive igneous rocks
the three kinds of plate boundaries
what are transform, divergent, convergent?
The layer of Earth that is solid due to the intense pressure it is under.
What is the inner core?
These natural features are made active by convection currents
What are volcanos?
The name of the supercontinent formed when all the continents were together.
What is Pangaea?
The name of the stream of mountains that curve along the sea-floor, extending into all of earth's oceans
The result of two continental plates moving along a transform boundary.
What is an earthquake?
The layer that makes up the lower part of the crust and the upper part of the mantle.
What is the lithosphere?
The three layers that make up the mantle.
What are the lithosphere, asthenosphere, lower mantle?
The four pieces of evidence that support the existence of Pangaea
What are fossils, climate, jigsaw plates, and landforms?
These are created when an oceanic and continental plate converge.
What are volcanos, earthquakes, and ocean trench?
