Hazard - ANSWER Natural process or event that is a potential threat to
human
life or property
Disaster - ANSWER Hazardous event that occurs over a limited time in a
defined area
Criteria:
1) Ten or more people killed
2) 100 or more people affected
3) State of emergency is declared
4) International assistance is requested
Catastrophe - ANSWER Massive disaster that requires significant amount of
money
or time to recover
Tectonic Cycle - ANSWER Refers to large-scale processes that deform Earth's
crust and
produce landforms
- Driven by forces within Earth
, - Involves the creation, destruction, and movement of tectonic
plates
Compositional Model - ANSWER Chemical layers
Mechanical Model - ANSWER Physical layers
Crust - ANSWER Outer rock layer of Earth
Mantle - ANSWER Surrounds the outer core, composed mostly of solid iron
and magnesium rich silicate rocks
Lithosphere - ANSWER Cool, strong outermost layer or sphere of Earth
Asthenosphere - ANSWER A hot and slowly flowing layer of relatively weak
rock
Continental Crust - ANSWER A solid, thin outermost layer of Earth
Oceanic Crust - ANSWER Earths crust located under the ocean
Plate Tectonics Process - ANSWER The driving force behind plate tectonics is
convection in the mantle. Hot material near the Earth's core rises, and colder
mantle rock sinks
Calculate distance between 2 locations based on plate movement rate -
ANSWER ?
Divergent Boundary - ANSWER A plate boundary where two plates move
away from each other
