What is the large movement of rock, soil and debris downward due to the force of gravity?
Mass Wasting
100
What is the difference between lava and magma?
Lava is simply magma that has reached Earth's surface.
100
What is the difference between cutback and pointbar?
Cutbacks are where the stream erodes away the river bank and the point bar is where sediment is deposited.
200
How many feet are in a mile?
5280ft.
200
Where are Earthquakes more likely to occur?
Along plate boundaries.
200
Which of the following is not a trigger for mass wasting? Low Shear Strength, Increased Water, Increased Steepness, Vegetation Removal, The Moon's Gravitational Pull, or Freeze Thaw Cycles?
The Moon's gravitational pull.
200
Define a lahar.
A destructive mudflow triggered by volcanic activity.
200
Define floodplain.
An area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
300
What is significant about a contour line forming a v when crossing a stream?
The V almost always points upstream.
300
What is the difference between the epicenter and the focus?
The focus is underground and the epicenter is on the surface above the focus.
300
List three ways to prevent mass wasting.
Improve Drainage, Vegetate Area, Anchor Slopes, Stabilize Angle of Repose by cutting back, avoid over-burdening the slope, etc...
300
What is the difference between a dormant and an extinct volcano?
An extinct volcano hasn't erupted in the past 10,000 years and isn't expected to, a dormant volcano isn't currently erupting but is expected to at some time in the future.
