Boundaries
What are the three types of boundaries?
What is convergent, divergent and transform?
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
What type of boundary is it when new crust forms?
Divergent Boundary
When an oceanic plate and continental plate collide.
subduction
When convergent oceanic and continental plates meet, what typically happens?
the oceanic plates subducts, or dips below the continental plate
What type of boundary is it when plates move toward each other?
What is Convergent boundary?
Where can one divergent boundary be found?
mid-ocean ridge or rift valley
What natural disasters are caused by plate tectonics? There are 3.
volcanic eruptions, earthquakes, tsunamis
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
How do we measure how strong an earthquake is?
Measuring Seismic waves using a Seismograph
These are broken parts of lithosphere that carry continents and oceans
What are tectonic plates?
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
