Plate boundary that has two plates moving AWAY from each other
What is a divergent boundary?
People did not believe Alfred Wegener's theory of Continental drift because he could not prove THIS
What is the way the plate tectonics are able to move?
This scientist discovered seafloor spreading
Who is Harry Hess?
Result of two Continental plates colliding
What is the formation of a mountain?
The reason the oceanic plate will sink when colliding with a continental plate
What is density?
(Which is more dense?????)
Plate boundary that has two plates moving TOWARDS each other
What is a convergent boundary?
Africa is warm now, but it used to be covered in ice
The shape of the continents match
The same fossil can be found on multiple continents
The same mountain ranges can be found on different continents
Newer ocean crust is found here on the mid-ocean ridge
Where is the middle of the ridge?
Where is the spot where magma rises up from the mantle?
Result of two oceanic plates colliding
What is an ocean trench?
The layer convection currents occur in
What is the mantle?
Plate Boundary that has two plates SLIDING PAST each other
What is a transform boundary?
Alfred Wegener was responsible for coming up with this theory
What is continental drift?
Responsible for the movement of plate tectonics and how seafloor spreading is possible
What are convection currents?
Result of an continental crust and oceanic crust colliding
What is a subduction zone?
How are volcanoes formed?
This event is caused by a release of energy
What are Earthquakes?
Subduction zones occur at this type of plate boundary
What are convergent boundaries?
The name of our continents when they were together and formed a super continent
What is Pangea?
The device Henry Hess used to prove there was seafloor spreading happening
What is a sonar device?
Result of two oceanic plates pulling apart
What is a mid-ocean ridge?
What is new ocean floor?
The reason our Earth layers are in the order that they are in.
What is density?
What are convection currents?
Result of two continental plates pulling apart
What is a rift?
The name of Ms.H's two cats.
Who are Kitty and Milly
