Layers in Layers
These are the layers of the Earth IN ORDER, starting from the outside and moving inside.
What is the crust, mantle, outer core, inner core?
This is the hottest layer of the Earth.
What is the inner core?
These two things can occur at convergent boundaries.
What are volcanoes, earthquakes, subduction, or mountains?
What is their movement?
What is "All the Earth"?
There are this many types of crust.
What is two?
This is the coldest layer of the Earth.
What is the crust?
These are the three types of convergent boundaries.
What is oceanic-oceanic, continental-continental, and oceanic-continental?
This is the theory that Alfred Wegener proposed to explain the existence of Pangea.
What is the theory of Continental Drift?
This refers to the process of hot material rising and cool material sinking, which creates movement.
What is convection current?
This is what makes continental crust different from oceanic crust.
What is size/density? (continental crust is thicker and lighter than oceanic crust).
This layer is where convection currents take place.
What is the mantle?
Subduction occurs at this plate boundary.
What is a convergent boundary?
This is the explanation for how tectonic plates can move.
What are convection currents in the mantle?
This is the name of the process in which one plate is pushed underneath another.
What is subduction?
These two layers can be found in the mantle.
What is the lithosphere and asthenosphere?
The crust and mantle make up this layer of the Earth.
What is the lithosphere?
This is the only natural disaster that occurs at transform plate boundaries.
What is an earthquake?
This is the name of the supercontinent that could form in the future.
What is Pangea Ultima?
This refers to the theory of plate movement through convection currents in the mantle.
What is Plate Tectonics?
Tectonics plates are found at this layer.
What is the lithosphere?
This layer, inside of the mantle, is what tectonic plates float on.
What is the asthenosphere?
Seafloor spreading only occurs at this plate boundary.
What is a divergent boundary?
These two things were used as evidence to prove the existence of Pangea.
What are fossil evidence and matching coastlines? (Also accepted: glacial evidence, rock evidence, similar plant/animal fossils).
This refers to the formation of new crust on the ocean floor.
What is seafloor spreading?
