Topo Maps
Define contour lines
they are lines that show elevation / or a change in elevation
Which type of wave is the first to arrive at a seismograph station?
P-Waves
This is when two plates are headed toward each other
Convergent boundary
The breaking down and moving of rock and other material is called what?
Erosion
Where to a majority of earthquakes come from?
plate boundaries interacting (convergent, divergent and transform)
If the lines on a topographic map are close together, what can you say about the elevation?
It is steep / mountain
Where do earthquakes originate from?
Inside Earth / The focus
What type of plate boundary is in California? (where two plates slide past each other)
Transform boundary
How will a steeper slope affect the rate of erosion?
It will increase the rate
Epicenter
Where an earthquake is located on Earth's surface
Why would we not see contour lines in the ocean?
The ocean has an elevation of zero
Which type of wave can travel through both solids and liquids?
P-waves
What is causing the plates to move?
Convection currents in the mantle
Which type of rock is the easiest to weather?
Sedimentary rock
Where do volcanoes occur?
When ocean crust and continental crust converge.
What are depression lines?
They have hash marks on them to indicate a lower point, dip, or depression in the landscape
What are the P and S waves "graphed" or "printed" on?
Seismogram
What type of plate boundary is at the mid atlantic ridge?
divergent
Deltas are formed mostly through which type of force? (weathering, erosion, or deposition)
Deposition
What happens when a continental plate and oceanic plate converge?
Subduction of the ocean plate, which creates a trench
Why shouldn't contour lines overlap?
Contour lines represent a specific elevation, if lines overlap then you cannot tell what is the true elevation of the landscape
How do P waves behave when they enter different layers of Earth's interior? Why do they do this?
They bend, due to the change in density
When plates diverge in the ocean, which allows new magma to rise up from the mantle. The magma cools and hardens, forming new sea floor.
What are the two types/ kinds of weathering?
Mechanical/Physical and Chemical
How are mountains created?
When 2 continental plates converge
