Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Obduction is a geological process whereby denser oceanic crust (and even upper mantle) is scraped off a descending ocean plate at a convergent plate boundary and thrust on top of an adjacent plate.
Obligate dependency links the evolutionary fate of the organisms involved, this coupling has the potential to result in both negative and positive consequences. [1] This coupling can enhance the ability of the organism to evolve because natural selection can influence two genomes at once, meaning there are more opportunities for a mutation to ...

Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. [2]
Valley of the T. rex is a Discovery Channel documentary, featuring paleontologist Jack Horner, that aired on September 10, 2001.The program shows Horner with his digging team as they travel to Hell Creek Formation in search for dinosaur fossils, while also following Horner as he presents his view of the theropod dinosaur Tyrannosaurus rex as a scavenger rather than a predator, as it is often ...
The term obligate can also be used in a biological context, in reference to species which must occupy a certain niche or behave in a certain way in order to survive. In biology, the opposite of obligate is facultative , meaning that a species is able to behave in a certain way and may do so under certain circumstances, but that it can also ...
