Similar to a person trying to walk in a straight line across a spinning merry-go-round, winds and ocean waters get deflected from a straight line path as they travel .

On average, the temperate deciduous forest remains above freezing throughout the year The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of sea water. c. Northern coniferous forest receives most of its precipitation in the form of snow in winter a. a stretched rubber band In general, ocean water is more dense than fresh water, since ocean water contains more salt.
