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
Who discovered the Mid-Ocean Ridge using Sonar
Where can one divergent boundary be found?
mid-ocean ridge or rift valley
What type of volcanoes are the Hawaiian Islands
Hot Spot Volcanoes
What type of boundary is it when new crust forms?
Divergent Boundary
When an oceanic plate and continental plate collide.
subduction
Pipe
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
Point on the surface of the Eath where earthquake happens ( directly over the FOCUS)
Epicenter
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
How do we measure how strong an earthquake is?
Measuring Seismic waves using a Seismograph
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.
