Exempel på hur man kan använda DRIFT i en mening

• Continental drift is the theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time.
• It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.
• This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.
• Plankton are the diverse collection of organisms that drift in water (or air) but are unable to actively propel themselves against currents (or wind).
• On the other hand, small-scale plasma instabilities (typically described by kinetic theory), such as the drift wave instability, are believed to be the driving mechanism of turbulent transport in tokamaks, which leads to high rate of particle and energy transport across the confining magnetic fields.
• The Allan variance is intended to estimate stability due to noise processes and not that of systematic errors or imperfections such as frequency drift or temperature effects.
• When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor, because they have no loosely bound, or free, electrons that may drift through the material, but instead they shift, only slightly, from their average equilibrium positions, causing dielectric polarisation.
• The term is sometimes mistakenly used as synonymous with frequency drift, which is an unintended offset of an oscillator from its nominal frequency.
• Long-term frequency changes are caused by changes in the oscillator elements that determine frequency, such as crystal drift, inductance changes, and capacitance changes.
• Till is a form of glacial drift, which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice.
• Genetic drift, also known as random genetic drift, allelic drift or the Wright effect, is the change in the frequency of an existing gene variant (allele) in a population due to random chance.
• Clearchus refused this owing to the insecurity that the Greeks had for their right flank, which tended to drift and was undefended, as the shields were held in the left hand.
• Drivers on I-380 experience an abrupt transition from the muted topography of the Iowan surface to the rolling hills of the Southern Iowa drift plain, four miles south of North Liberty.
• The rugged terrain is due both to the lack of glacial deposits, or drift, and to the incision of the upper Mississippi River and its tributaries into bedrock.
• Commonly referred to as the "Leaf Mountains", it is here in Otter Tail County whereby two moraines, the Fergus Falls Moraine and Leaf Hills Moraine, unite to create a belt of drift hills, stretching across five townships, giving the region profound definition.
• Initially, a dozen boats entered the river from Old Saybrook to Rocky Hill, cast their nets, which can be several hundred feet long, and drift with the tide while waiting for a school of chud.
• Still, the inlet is blamed for coastal erosion because it interrupts the longshore drift on the sound.
• Army Corps of Engineers handling of the barrier beach—particularly in response to a series of groynes at Shinnecock Inlet that have created major beach erosion "downstream" in the longshore drift.
• During summer, popular activities on the Klickitat River include recreational drift boating, kayaking, and rafting.
• The Maringouin has its sources near Long Lake, on the west, and on the south interlocks with the upper branches of the Chippewa River, among some lakes, enclosed by drift ridges, which are, by barometrical measurement, eight hundred and seventy-one feet above Lake Superior.
