These are the two plate boundaries in which mountains can form
What is convergent and divergent boundaries
100
What is the word to describe anything that gets shot out of a volcano and what type of eruption would that occur at?
Pyroclastic Material. Violent eruptions.
100
What causes an earthquake?
Sudden release of energy between two tectonic plate boundaries.
100
What do we call a sudden release of energy beneath Earth's surface?
Earthquake
100
what layer is Earth's tectonic plates a part of?
lithosphere
200
When a rock is said to "bend" this is being created and what are the two types?
Folding. Anticline and syncline
200
What type of material would flow onto Earth's surface during a nonexplosive volcanic eruption?
lava
200
Describe the difference between the focus and epicenter of an earthquake.
Focus is the point underground in which an earthquake first is detected. The epicenter is on earths surface directly above the focus.
200
A type of stress that squeezes rock together?
What is compression
200
what do we call the feature of a volcano where there is a depression around the volcanic vent?
caldera
300
What are the three different faults and describe each one?
Normal, Reverse, Strike Slip
300
Give an example of a shield and composite volcano.
shield - Hawaii Composite - Mt. St. Helens
300
What do we call the energy that travels through earths crust after an earthquake occurs?
seismic waves
300
Return of rock back to its original shape after deformation
elastic deformation
300
What is the difference between deformation, folding and a fault?
Deformation is the change of a rock folding is the bending of a rock fault is the breaking of a rock
400
What are the three types of mountains and describe each one?
Folded, Volcanic, Fault Block
400
Describe the ring of fire and name the plate on which they are all located around.
An active are that includes many volcanoes surrounding the pacific ocean. The pacific plate.
400
What causes the most human injuries during an earthquake and what are some of the aftermaths?
collapsing buildings and tsunamis
400
These can form when there are violent eruptions in a volcano.
Craters
400
What is a warning sign that occurs to let people know a tsunami is going to happen?
The water retreats back hundreds of yards from the shore.
500
Name the three faults, what boundaries are at each, and what stress occurs.
Normal- Divergent boundaries and tension Reverse- Convergent and compression Strike slip- Transform and shear
500
Name the three types of volcanoes and briefly describe how they form and what they look like. Also include the type of eruptions that occur at each.
Shield- Gently sloping sides, mild eruptions Composite - Mountain looking volcano, mild/explosive eruptions Cinder cone- Form from its own debris and has explosive eruptions
500
How does elastic rebound take place?
rocks are stretched or compressed and then suddenly return to their previous shape.
500
This is where magma is stored.
What is a magma chamber
500
Describe a hot spot and where is there an active one occurring today?
a hot spot is where a column of magma rises up from the mantle to form a mantle plume where that magma is released into the ocean creating new land. The hawaiian island are an example.
