resistance to flow. Dependent on: temperature, composition, and dissolved gases.
What is viscosity?
100
Produced from igneous rocks, sedimentary rocks, and other kinds of rocks. Some examples are gneiss, slate, marble, schist, and quartzite.
What are Metamorphic Rocks?
100
Landmasses split into two or more smaller segments to form a new ocean basin.
What is a Continental rift?
100
collision of two plates
What are convergent plate boundaries?
100
point on the Earth’s surface that is directly above the focus, or the point where an earthquake explosion originates underground.
What is the epicenter?
200
The volcanic rock ejected during an eruption.
What are pyroclastic materials?
200
Molecular collision
What is conduction?
200
Location of subduction zones, where plate sinks into the underlying mantle. Located primarily around the Pacific Ocean (“Ring of Fire”).
What are Active margins?
200
Plates that move apart. Driving force behind seafloor
What are divergent plates?
300
Steep-sided, symmetrical cones built of alternating layers of lava flows and volcanic ash that may rise as much as 8,000 feet above their bases. These volcanoes explode violently due to trapped gas (ex: Mt. Fuji, Mount St. Helens, Mount Rainier).
What is a Composite Volcano or Stratovolcano?
300
heat transfer by material motion
What is convection?
300
Experience little volcanism and few earthquakes. Found along most coastal areas that surround the Atlantic Ocean.
What are passive margins?
300
Longitudinal waves that moves in the direction the wave propagates.
What are Compressional or P waves?
400
built almost entirely of fluid lava flows that cover thousands of kilometers (ex:Mauna Loa, Hawaii).
What is a Shield Volcano?
400
Heat transfer by electromagnetic waves
What is radiation?
400
Processes that collectively produce a mountain belt. Mainly occurs at convergent plate boundaries
What is Orogenesis?
400
Transverse waves that moves perpendicular to wave propagation (ex. ocean waves).
What are shear or S waves?
500
simplest volcano, formed when particles and blobs of lava eject from a single vent to form a circular, oval cone that resembles a crater.
What is a Cinder Cone?
500
Two plates slide by one another in opposite directions
What is a Transform Fault?
500
Spring-mass device that measures motion of the ground. Using data from 3 separate seismic stations, we can determine the location of an earthquake.
