Volcanoes occur here
What are plate boundaries?
Vibrations in the ground that result from movement along faults.
What are Earthquakes?
A number of rigid, but moving, pieces of Earth's surface
What are tectonic plates.
The point where two plates move apart from each other.
What is a divergent boundary?
Volcanoes form mostly at these types of plate boundaries
What are convergent and divergent boundaries?
A crack or fracture in Earth's lithosphere along which one block of rock moves toward, away from or past another.
What is a fault?
The supercontinent that Wegener suggested occurred on Earth about 300 million years ago.
What is Pangea?
The point where two plates move together (toward each other.)
What is a convergent boundary?
A zone of frequent earthquakes and volcanic eruptions that encircles the Pacific Basin.
What is Ring of Fire?
Waves of energy that travels through the Earth, away from an earthquake in all directions.
What are seismic waves?
a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
What is Plate Tectonics?
The point where two plates slip past each other.
What is a transform boundary?
A region of volcanic activity in the middle of a tectonic plate.
What is a hot spot?
Rocks bend when pushed or pulled. Also the feeling right before a test.
What is Stress
Scientists think continents were once a large single landmass that broke apart and then the continents slowly DRIFTED to their present locations. What is the name given to this hypothesis?
What is continental drift?
This is the term for one plate being forced underneath another plate.
What is Subduction?
These two types of crust form a volcano at a convergent boundary
What are Oceanic and Continental Crust?
The bending tilting, and breaking of the Earth's crust, the change in the shape of rock in response to stress.
What is deformation?
This is the mechanism (what causes) the plates to move
What are convection currents in the mantle
Earthquakes and Volcanoes are usually located in relation to these
