Boundaries
Two tectonic plates that collide together.
What is convergent boundary?
A continental plate collides with a continental plate, it forms this landscape.
What is a mountain?
When two plates are in a convergent boundary and the more dense plate slides underneath the less dense plate, this is called _____________.
What is subduction?
The scientist that proposed the continental drift theory.
Who is Alfred Wegener?
Pangea
What is a supercontinent?
Two tectonic plates that pull away from each other.
What is divergent boundary?
A continental plate scrapes against an oceanic plate causing this to occur.
What is an earthquake?
This is the thinner, yet more dense tectonic plate?
What is oceanic?
The scientist that proposed the theory on seafloor spreading.
A hot, less dense magma rising up, losing it's temperature making it become cooler and less dense causing it to fall down.
What are convection currents?
Two tectonic plates that scrape against each other.
What is transform boundary?
This oceanic plate pulls away from another oceanic plate causing new rock to form. What is the evidence to support this?
What is a mid-oceanic ridge?
When two oceanic plates collide they form a __________.
What is trench?
What were the 3 pieces of evidence Alfred Wegener found to try and prove his hypothesis?
What is fossils, geology (types of rocks, landforms, plants), and climate?
Will the earth grow larger due to seafloor spreading? Why or why not.
No. Because as more crust is being made (Divergent boundaries), crust is also being destroyed in convergent boundaries.
Define divergent boundary.
Two continental plates in a divergent boundary form this?
What is a rift valley?
Geologists measure the speed and direction of plate movement by studying these.
What is hot spot?
The proof of seafloor spreading.
New rock is found at the boundary between the two oceanic plates whereas older rock is found further away.
Younger rock is found near this location in the ocean.
What is mid-ocean ridge?
This boundary is destroying crust.
What is convergent?
What is a divergent boundary in the ocean.
When oceanic and continental plates are in a convergent boundary, this will form.
What is volcano?
This causes tectonic plates to move.
What are convection currents?
Ms. Boyett's birthday.
When is February 17th?
