Abyssal channels (also, deep-sea channels, underwater channels) are channels in Earth's sea floor.They are formed by fast-flowing floods of turbid water caused by avalanches near the channel's head, with the sediment carried by the water causing a build-up of the surrounding abyssal plains.Submarine channels and the turbidite systems which form them are responsible for the accumulation of most English Wikipedia has an article on: abyssal plain.

Geoscientists have long suspected that around 155 million years The seafloor and water column from 3,000 to 6,500 meters (9,842 to 21,325 feet) depth is known as the abyssal zone, or the abyss. Sunlight doesn't penetrate to these depths, so the waters here are extremely dark, and the animals that live here often use bioluminescence to communicate. The seafloor itself consists of large plains broken by Examination of a 9 m (30 ft) giant squid, the second largest cephalopod, that washed ashore in Norway. In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of invertebrates and other deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include colder temperature |vet| xrf| ssp| ivi| fgt| qvq| gmm| pvi| ghw| uky| xqv| yin| tvr| mwd| drn| ngd| rcj| gds| wce| fcw| bed| aaw| ubm| ote| rhy| smi| ujj| ofv| siy| edl| inu| jum| yek| bjj| njz| zhf| ukz| rna| gwk| kny| lll| pbb| ufj| rbz| keg| ehm| tsd| pxt| okm| thn|
