Landforms
This landform is created when divergent plates expose the mantle, which eventually cools and hardens.
What is a rift valley?
These are tectonic plates that separate from one another.
What are divergent plates?
This landform is caused by transform plate boundaries.
What is a Fault?
These are tectonic plates that cause earthquakes.
What are transform plates?
This is the scientist who thought of Pangaea (the idea of all the continents being once joined in a single huge continent).
Bonus: The hypothesis of continents once formed a single landmass, broke up, and drifted to their present locations. +100
Who is Alfred Wegener?
Bonus: What is the Continental Drift?
This landform, caused by CONTINENTAL convergent boundaries, increases in size the more the plates collide.
What is a mountain?
These tectonic plates form volcanoes on land and underwater.
What are convergent plates?
The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.
This landform is created due to subduction.
What is a trench?
These two things form the lithosphere.
What are the crust and upper mantle?
This is a chain of underwater mountains that runs through the center of the Atlantic Ocean and where sea floor spreading takes place.
What is the Mid-Ocean Ridge?
This is what causes tectonic plates to shift in the first place.
Bonus: Where does this happen?
What is convection?
Bonus: Asthenosphere
South America and Africa are likely to be what type of plate boundaries?
What are divergent plates?
This layer of the mantle is very rocky and solid and is the upper layer (closest to the crust).
When a plate with oceanic crust collides with a plate with continental crust, and the oceanic crust sinks into the asthenosphere.
What is a subduction zone?
