geo 4 1st midterm
graphical scale
A graphical scale is a small ruler that can be used to convert distances covered on a map to real-world distances.
large scale
A large scale map shows more detail for the mapped region (e.g., buildings appear larger)
true
A majority of earthquakes occur on or near plate boundaries.
numeric scale
A numeric scale is a ratio defining the conversion factor between distance measured on a map and real-world distance.
true
Hot spots have active volcanoes above them on the Earth's surface and moving plates carry the volcanoes away from their hot-spot source.
true
Strike-slip (transform) faults usually link spreading centers or connect spreading centers with subduction zones.
Icelandic type eruptions
The most peaceful eruptions
true
The movements of the lithospheric plates are directly responsible for the vast majority of the earthquakes, volcanic eruptions, and mountains on Earth.
pyroclastic flows
The primary cause of death from explosive volcanic eruptions is
true
The rates of plate movement are comparable to those of human fingernail growth.
viscosity, volatiles, volume
The three Vs of volcanology
true
The types of rock or sediment on which a structure's foundation sits are of paramount importance with respect to whether the structure will be damaged by shaking from an earthquake.
topography
Topography is the study of the shapes and terrain of the surface of the Earth.
divergent and convergent plate boundaries
Volcanoes are formed at
true
Volcanoes tend to occur mostly along plate boundaries.
Pushing together plate motions, occurrence of earthquakes, and reverse faulting
characteristics describe a convergent plate boundary
Pulling apart plate motions, occurrence of earthquakes, and normal faulting
characteristics describe a divergent plate boundary
Horizontal sliding plate motions, occurrence of earthquakes, and strike-slip faulting
characteristics describe a transform plate boundary
reverse
faults are commonly found at areas of plate convergence where subduction or continental collision occurs.
contour lines/contours
map features used to show your vertical (up-down) position
small scale
small scale map that shows less detail (e.g., buildings appear smaller).
push together
type of motion is associated with convergent plate boundaries
pull apart
type of motion is associated with divergent plate boundaries
slide past
type of motion is associated with transform plate boundaries
lahars, debris avalanches, tsunamis
volcanic processes can cause
