Tethys
Tentaculata class of subphylum Ctenophora (phylum Cnidaria), with retractile tentacles. Most Ctenophora belong to this group.
tephra (volcanic ejecta, ejectamenta) collective term for all fragmental materials ejected by a volcano and transported through the air; includes volcanic
dust, ash, cinders, pumice, and bombs.
terrace, marine narrow coastal strip, sloping gently seaward, consisting of loose
sediment or rock and veneered by a marine deposit (silt, sand, fine gravel).
~coast.
terrestrial sediments sediments deposited on land.
terrigenous sediments sediments consisting of material eroded from the land
surface. This material is liberated from igneous, metamorphic, and preexisting sedimentary rocks by chemical and physical weathering, and transported by water, wind, or ice. Most of the surface sediments in shelf seas consist of
terrigenous material.
territorialism some animals have a restricted home range and defend either
individually, in pairs, or in groups a specific area against conspecifics for
feeding, resting, reproduction, or other activities. By such territorial behavior, which often occurs in crabs, fish and birds, population densities may be
restricted, while within a territorial population distribution tends to approach
an even distribution.
territorial sea defined by the international conferences held in The Hague in
1930, under the auspices of the League of Nations, and by UNCLOS I,ll and III as
a 12-nautical-mile zone, measured from the baseline (~coastline,legal aspects) on
which the coastal state has absolute sovereignty. Originated from the vague
"cannon-shot" rule the USA and Britain had earlier settled on a 3-mile zone,
which was by no means universally accepted. Scandinavian countries originally had a 4-mile limit, France 6 miles, and Czarist Russia 12 miles.
Tertiary ~geological time scale.
tertiary production ~production.
testis organ which produces sperm. In Vertebrata it also produces sex hormones.
Tethys the late Mesozoic sea which separated laurasia from Gondwana. The Tethys
originated from the break-up of Pangea and was closed by the collision of
Eurasia (Europe and Asia) with Africa and India during the Neogene. ~continental displacement.
