■ NOUN
crust
▪
Continental lithosphere stands higher than oceanic lithosphere because continental crust is both of greater thickness and lower density than oceanic crust.
▪
This would be expected from differences in the density and thickness of continental and oceanic crust .
▪
The composition of displaced terranes ranges from that of typical oceanic crust to significantly less dense granitic rock with clear continental affinities.
▪
It appeared that these offsets marked some kind of lateral movement between adjacent sections of oceanic crust .
▪
Its purpose is to gather sufficient information to answer questions about magma chambers in oceanic crust .
▪
From these observations, Hofmann and I proposed that plumes consist in part of deeply subducted oceanic crust and sediment.
▪
Hess mistakenly thought that the oceanic crust consisted of altered peridotite, the material of the mantle itself.
▪
Alternatively, subducted oceanic crust may be able to pull adjacent continental crust down into the asthenosphere.
island
▪
Comparison of their chemistry with that of magmas erupted on oceanic islands demonstrates the plumes differ chemically from the upper mantle.
▪
Darwin himself had explained the strange inhabitants of isolated oceanic islands such as the Galapagos in terms of accidental migrations from the nearest mainland.
▪
This period was sufficiently long for the widespread planation of oceanic islands , many of them volcanic.
lithosphere
▪
Continental lithosphere stands higher than oceanic lithosphere because continental crust is both of greater thickness and lower density than oceanic crust.
▪
The heavy oceanic lithosphere descends into the mantle, beneath the lighter continental lithosphere.
▪
The sequence of continental-margin orogen development begins with the subduction of oceanic lithosphere at, or close to, a continental margin.
▪
Perhaps more significant is the thickening of oceanic lithosphere as it moves away from mid-oceanic ridges.
▪
Such mountain belts develop when the oceanic lithosphere originally lying between two continents is eventually consumed.
▪
Cool, thick, old oceanic lithosphere is gravitationally unstable as it is generally denser than the asthenosphere over which it lies.
▪
Where oceanic lithosphere is subducted beneath another oceanic part of a plate the associated volcanic activity and produce an intra-oceanic island arc.
▪
Subduction of oceanic lithosphere beneath a plate carrying continental crust gives rise to a continental-margin orogen.
plate
▪
Some of the sea-floor sediments, muds, and oozes sitting on top of the oceanic plate also get melted.

▪
Power surfers are towed behind a jet-ski into massive oceanic swells that move too fast to catch by paddling conventional surfboards.
▪

▪
The second category is closely related to oceanic trenches and their associated island arcs or mountain belts.
▪
This would be expected from differences in the density and thickness of continental and oceanic crust.
▪
Thus the volcanic rocks formed are drastically different from their oceanic counterparts.
▪
Tsunamis are caused by violent oceanic events such as earthquakes, undersea landslides, volcanic explosions, and impacts.
