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
