Exempel på hur man kan använda DEGLACIATION i en mening

• Situated below the peak of the Corno Grande is the Calderone glacier, although deglaciation has significantly reduced the glacier's size.
• A 2017 study concluded that similar conditions to today's Antarctic ozone hole (atmospheric circulation and hydroclimate changes), ~17,700 years ago, when stratospheric ozone depletion contributed to abrupt accelerated Southern Hemisphere deglaciation.
• The populations sheltered in Iberia, descendants of the Cro-Magnon, given the deglaciation, migrate and recolonize all of Western Europe, thus spreading the R1b Haplogroup populations (still dominant, in variant degrees, from Iberia to Scandinavia).
• Numerous studies on chronology and palaeoclimate of last deglaciation show a cooling event within Bølling–Allerød warming that reflects the occurrence of Older Dryas.
• Jusiene, 2004, "Glaciolacustrine kame terraces as an indicator of conditions of deglaciation in Lithuania during the Last Glaciation".
• The populations sheltered in Iberia, descendants of the Cro-Magnon, given the deglaciation, migrate and recolonize all of Western Europe, thus spreading the R1b haplogroup populations (still dominant, in variant degrees, from Iberia to Scandinavia).
• A regional glaciation spanning the latest Sakmarian and the Artinskian, known as P2, occurred in Australia amidst this global pulse of net warming and deglaciation.
• Other mechanisms suggested for triggering volcanism in the Northern Cordilleran Volcanic Province include mantle plumes, deglaciation and slab windows, although continental rifting is the most accurate mechanism for activating volcanism in the volcanic zone.
• The deep oceans were depleted in radiocarbon during the deglaciation following the LGM, which has been hypothesised to be the result of sluggish meridional overturning circulation or due to a release of volcanic carbon or methane clathrates into abyssal waters.
• Glacial refugia are areas that climate changes were not as severe, and where species could recolonize after deglaciation.
• Emerged shorelines relative to the sea level are created because of three main causes: tectonic movements that result in changes in terrain elevation, isostatic lifting and warping due to unloading of ice sheets and sea water masses during deglaciation, and eustatic drops of sea levels during glaciations.
• planktonic foraminifers, stable isotope ratios, changes in sediment texture, and reworked calcareous nanofossils, preserved in its sediment also recorded the impact and chronology of meltwater floods that flowed down the Mississippi River on the Gulf of Mexico during the last deglaciation.
• After deglaciation during the latter half of the Early Permian, the land became dominated by glossopterids (an extinct group of seed plants with no close living relatives), most prominently Glossopteris, a tree interpreted as growing in waterlogged soils, which formed extensive coal deposits.
• Over 60 geoarchaeological sites bridging the Pleistocene–Holocene transition (last deglaciation) exhibit this "black mat"; it is a black organic-rich layer in the form of mollic paleosols, aquolls, and diatomites.
• Ongoing research reconstructing Beringian paleogeography during deglaciation could change that estimate and possible earlier submergence could further constrain models of human migration into North America.
• Examples include: the sectoring patterns sometimes evident in microbial colonies; phylogeographic sectoring of lineages, inferred to have rapidly expanded into new terrain-following deglaciation; the island progression rule; and sudden biological replacement (lineage turnover) following extirpation.
• The age of the uppermost argillaceous part of the third deglaciation sequence (297 Ma) was determined from zircons of a tuffaceous bed sampled in a roadcut in the Western Cape Province, South Africa.
