Earth’s lithosphere is made up of what layer/s?
Crust
Mantle
Crust and Mantle
Crust and upper mantle
What do you call the broken segments that make up the lithosphere?
Crust
Mantle
Core
Plates
Mountain building
earthquake recurrence interval
transform plate boundary
subduction
Where an oceanic crust converges with a continental or oceanic a very deep feature is made called a
Ridge
Trench
crater
oceanic dip
There have been 8 earthquakes over a 320 year period in an area. What is the recurrence interval?
1240 years
12 years
40 years
20 years
How do you calculate the recurrence interval
Multiply the number of years of data by the number of earthquakes
Divide the number of years of data by the number of volcanoes
Add up all the earthquakes that occurred in a time frame
Divide the number of years of data by the number of earthquakes
tension
divergence
The stress that is formed when rocks are pushing in opposite direction at a transform boundary.
compression
tension
shear stress
transform
Parallel forces acting in opposite directions
compression
shear
tension
Transform
Squeezing force that acts from opposite sides
compression
shear
tension
congergent
A pulling apart force
compression
shear
tension
divergence
_____________ occurs when stress acting on a rock causes the rock to change shape.
fracture
strain
compression
uplift
Which of the following is landform is created at Continent- Continent convergent boundaries?
Volcanic Mountains
Earthquakes
Non-volcanic Mountain Ranges
Both volcanoes and earthquakes
Which of the following is the a picture of a ocean to ocean convergent boundary?
None of those show a ocean to ocean convergent
What formations happen at ocean to ocean subduction zones?
Deep oceanic trenches
Mountain Ranges
Coastal Volcanic Mountains
Volcanic island arcs
Which plate is the SUBDUCTING or sinking plate in a convergent boundary?
The dense oceanic plate
The Thick continental plate
Neither
Both ocean and continental plate can sink.
Fill in the blank: The oceanic plate is _______ dense than the continental plate so it sinks, or subducts, under the continental plate.
Less
More
Same
Select all that are true about oceanic crust
older crust is formed close to the mid-ocean ridge
older crust is found farther away from the mid-ocean ridge
older oceanic crust is more dense
older oceanic crust is less dense
oceanic crust is made of the igneous rock granite
Molten material adds new crust to the ocean floor, pushing continents apart, in a process called
continent spreading
original horizontality
continental crust
seafloor spreading
Which point on the diagram represents the mid-ocean ridge?
point A
point B
point C
point D
Which is TRUE about the continental crust?
It is thinner than oceanic crust
It is denser than oceanic crust
It is thicker but less dense than the oceanic crust
It is thinner and more dense than the oceanic crust
The soft layer of rock that the lithosphere moves on is the _________________________.
core
asthenosphere
lithosphere
crust
What type of Boundary is this? What event will occur at this boundary?
Transform / Earthquakes
Subduction / Volcano Eruption
Tornado / Rain
Mountain Building / Volcanism
A boundary that doesn't create or destroy crust is called a:
Transform Boundary
Convergent Boundary
Divergent Boundary
Rift Valley
What are the two types of crust?
Convergent and Divergent
Lithosphere and Asthenosphere
Continental and Oceanic
Trench and Island Arc
What happens at the boundary where a continental plate and an oceanic plate collide?
The two plates are moving
Mountains develop on edge of the oceanic plate
The continental plate slips under the oceanic plate
The oceanic plate is forced down under the continental plate
How is subduction zone formed?
When two plates slide each past each other
When two plates move away from each other
When two plates move toward each other
When one tectonic plate sinks below another
What happens when two continental plate collide?
One plate will go under and subducts.
Both two plates will go downward.
The plates will fold and create mountains.
Plates will melt later.
compression
Which point on the diagram represents a trench?
point A
point B
point C
point D
Which is not a result of stress on rock?
Elasticity
Fracture
Compaction
Deformation
