Plate Boundaries
This type of plate boundary DOES NOT cause volcanoes to form.
What is a Transform Plate Boundary?
Which scale is used to report the intensity of an earthquake?
What is the Mercalli Scale?
What is the name of the area where we find a majority of the worlds volcanoes?
What is the Ring of Fire?
Who came up with the Continental Drift Hypothesis?
Who is Alfred Wegener.
At this kind of fault, Rocks push together and roll or thrust over each other. This creates a stress called compression.
What is a Reverse Fault?
What is the sideways/downward movement of a plate boundary of the earth's crust into the mantle beneath another plate.
What is Subduction?
What type of plate boundaries cause earthquakes?
What are ALL of them!
A volcano found in the center of a tectonic plate tends to be a result of which phenomenon?
What is a Hot Spot?
What makes up the Lithosphere?
What are the Upper layer of the mantle and the crust.
This kind of fault has "shearing" stress and rocks are being pushed in two, opposite, sideways directions.
What are Strike-Slip Faults?
Which type of plate boundary is most responsible for the formation of the Himalayan Range?
What is a Continental-Continental Convergent Boundary
When taking about Earthquakes, what does Magnitude measure?
a measure of the amount of energy released at the source of the earthquake
Name 3 types of Pyroclastic Material.
What are Ash, Dust, Pumice, Lapilli, Lava Bombs & Cinders?
What is responsible for the movement of plate boundaries?
What are convection currents.
Name 3 types of Hazards associated with Volcanic Eruptions.
What are: Ash, Poisonous Gasses, Volcano Bombs, lava, and mud/landslides.
What type of plate boundary results in ocean ridges or rift valleys on land?
What are Divergent Plate Boundaries?
P-waves occur before S-waves. What is the other primary difference between the two?
(hint: think of what they can go through)
P-waves can move through solids, liquids,and gases. S-waves can only move through solids.
What is a Lahar flow?
What is a mud flow that occurs after a volcanic eruption and contains ash and melted snow.
What happens to the crust at Divergent Plate Boundaries?
It is being Created.
What kind of lava would you typically find at a shield Volcano?
What are relatively fluid and low viscosity.
What is the reason oceanic plates subduct under continental plates?
Oceanic plates are more dense.
What direction(s) do seismic waves travel from the focus of an earthquake.
What are ALL directions.
What type of Volcano is Mount Saint Helen's?
What is a Composite Volcano?
What were are 2 of the observations Wegener made to support his continental drift hypothesis?
Matching Fossils, The Continental Puzzle, Rock Types and Structures & Ancient Climates
Where does the magma/lava from volcanoes come from?
The asthenosphere!!!
