They are smaller in land area, and separated from surrounding landmasses, be it the mainland or adjacent islands, by a certain amount of water.
High detrital fluxes indicate enhanced precipitation runoff from surrounding landmasses during a period of maximum southward shift of the Intertropical Convergence Zone.
These glaciations may have played a large role in mass extinctions of species that had previously thrived in the shallow seas surrounding landmasses.
Sea level fell substantially, wiping out much of the shallow-water habitat surrounding major landmasses.
However, Mae Sot is situated at a higher northern latitude and there is a much larger landmass surrounding it.
The Arctic Ocean, on the other hand, may be regarded as a mediterranean ocean, a sea surrounded by landmasses.
A simplified but representative three-dimensional geological model of the UK landmass and surrounding seas is used to provide an indication of the surface electric field for various amplitudes and orientations of external magnetic field variations.
Species were isolated by the uplift of major mountain chains along the suture zones of Pangea and by the lowering of sea level associated with climatic changes in the Permian, but there were also numerous opportunities for dispersal of biota across the large landmass and surrounding Panthalassic and PaleoTethys Oceans (Ross and Ross 1985; Perez-Huerta 2007).
The geologic activity associated with the Arabian Peninsula altered the historical connectivity of this landmass to surrounding continents, and as a result opportunities for faunal exchanges with particular continents occurred in temporally distinct periods.
We have surrounded the Russian landmass with military assets and a coordinated defense alliance through NATO.
