Boundaries
What type of boundary is it when plates move toward each other?
convergent boundary
The lithosphere is a permanent structure of the Earth that doesn't move. True or false?
false
Where can one divergent boundary be found?
mid-atlantic ridge
Which decade was Alfred Wegener's theory of continental drift proven?
1950's
What type of boundary is it when new crust forms?
Divergent Boundary
When an oceanic plate and continental plate collide.
subduction
Where can slide/transform boundaries be found? (HINT: in the USA)
San Andreas Fault, California
Earth's upper crust and upper mantle broken into sections that are in constant, slow motion driven by movement in the mantle is called ______________.
plate tectonics
What are the three types of boundaries?
Convergent, Divergent, Transform/Slide Boundaries
The layer of Earth we live on.
crust
What natural disasters are caused by plate tectonics? There are 3.
volcanic eruptions, earthquakes, tsunamis
When convergent oceanic and continental plates meet, what typically happens?
the oceanic plates subducts, or dips below the continental plate
What is Continental Drift Theory?
That continents have moved slowly to their current locations. Presence of fossils, rocks, and mountains on different continents help support this idea.
What type of boundary is it when two plates slide past each other?
Transform Boundary
What causes plates to move?
convection currents
What mountain range is formed by convergent boundaries?
Himalayan Mountain Range (Himalayas)
What man was not trusted with his idea of movement of plate tectonics?
Alfred Wegener
What convergent boundaries occur, it can cause land to raise up and this is called _________.
uplift
What are plate tectonics?
broken parts of lithosphere that carry continents and oceans
Plate tectonics can be destructive, but their movement is not always destructive. True or false?
true
Plate boundary movements underwater can cause tsunamis. True or false?
true
What is seafloor spreading?
New ocean floor is created as molten material from the earth's mantle rises in openings between plates and spreads out.
