Ch 1-2
dependent
rocks formed when other types of rocks are cooked by heat and pressure
metamorphic
this event was probably directly responsible for laying down most of Earth's sedimentary rock layers
Flood
metric unit oceanographers use to measure hydostatic pressure
kilopascal
an area of the sea that exceeds 6000m in depth
hadal zone
a volcano made of alternating layers of lava and ash
composite
regions of the earth's surface where limestone is exposed and abundant
karst regions
the idea that the natural laws in operation today have existed throughout Earth's history
uniformity
main factor that affects the color of the oceans
natural color
a current made of seawater mixed with mud or silt and can erode the ocean floor to produce submarine canyons
turbidity current
weaker earthquakes that often follow an earthquake at frequent intervals for days or months
aftershocks
type of rock that consists of smooth pebbles embedded in hardened sand or clay
conglomerate rock
the fittest and strongest organisms are most likely to survive and reproduce
natural selection
type of tide that occurs when there is one high tide and one low tide each day
diurnal tide
substance that makes up most of the salt in the oceans
sodium chloride
when rocks on one side of a fault are shoved on top of the rocks on the other side of the fault
thrust fault
type of weathering that involves the breaking or peeling away of rocks into layers
exfoliation
a fossil organism found in strata that are supposedly too old or too young to contain that organism
anomaly
this comes closer to the surface because plates are spreading apart at the Mid-Atlantic Ridge
magma
underwater valley that gives mid-ocean ridges the appearance of having twin mountain ranges
rift
the ability to duplicate an experiment several times while keeping all factors as similar as possible between experiments and coming to the same conclusion
repeatability
natural ridges that form when water flow causes sediments to drop along the edge of a river's channel
levees
the technique evolutionists use to assign supposedly exact ages to rock and fossils
radiometric dating
the mass of foaming water formed when waves wash up onto a beach
surf
circular paths that ocean currents move in
gyres
