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
List 2 features that are left behind as a glacier melts
Kettle, esker, erratic, moraine, till, delta
The breaking down and moving of rock and other material is called what?
Erosion
Kettle
A depression made by a broken of piece of glacier, which eventually melts and fills the depression with water
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 are the two types of glaciers?
Continental and Alpine
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 a terminal moraine?
The furthest moraine left behind. It shows how far the glacier advanced
Which type of rock is the easiest to weather?
Sedimentary rock
Surface waves
The slowest type of wave, which also causes the most damage
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 does it mean for a glacier to advance?
It is growing and/or moving forward.
Deltas are formed mostly through which type of force? (weathering, erosion, or deposition)
Deposition
Erratic
a boulder or large rock that was deposited from a glacier somewhere other than it's original location
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
Define a retreating glacier
When a glacier is melting faster than it forms
What are the two types/ kinds of weathering?
Mechanical/Physical and Chemical
Contour Interval
The difference in elevation between contour lines
