Changes in Ocean Geometry Over the Past Billion Years
... A very active region tectonically, with lots of volcanoes Several oceanic plates disappear (Izanagi) and appear (Kula) here. Until 133 Ma, still restricted circulation resulting in organic-rich shale deposits—but there is also strong upwelling, helping biologic activity. Thus some thermohaline circu ...

... Signs of Coastal Erosion • Wave-cut notches: An indentation cut into a sea cliff at water level by wave • Sea caves: cave formed primarily by the wave action of the sea • Sea arches: form where cliffs are subject to erosion from the sea • Sea stacks: steep and often vertical column of rock in the s ...
