adj.1. Lasting for a markedly brief time: "There remain some truths too ephemeral to be captured in the cold pages of a court transcript" (Irving R. Kaufman).
2.Living or lasting only for a day, as certain plants or insects do.
n.A markedly short-lived thing.
[From Greek ephēmeros : ep-, epi-, epi- + hēmerā, day.]
ephemerality e•phem'er•al'i•ty or e•phem'er•al•ness n.
ephemerally e•phem'er•al•ly adv.
Ephemeral things (from Greek εφήμερος - ephemeros, literally "lasting only one day"[1]) are transitory, existing only briefly. Typically the term is used to describe objects found in nature, although it can describe a wide range of things.(
Geographical examples
An ephemeral waterbody is a wetland, spring, stream, river, pond or lake that only exists for a short period following precipitation or snowmelt. They are not the same as intermittent or seasonal waterbodies, which exist for longer periods, but not all year round.
Examples of ephemeral streams are the Luni river in Rajasthan, India, Ugab River in Southern Africa, and a number of small ephemeral watercourses that drain Talak in northern Niger. Other notable ephemeral rivers include the Todd River and Sandover River in Central Australia as well as the Son River, Batha River and the Trabancos River.
Lake Carnegie in Western Australia and Lake Cowal in New South Wales are ephemeral lakes. Lake Tuzkan and Mystic Lake in California are ephemeral.
There are also ephemeral islands such as Banua Wuhu and Home Reef. These islands appear when volcanic activity increases their height above sea level, but disappear over the course of several years due to wave erosion. Bassas da India, on the other hand, is a near-sea level island that appears only at low tide.
Biological examples
Many plants are adapted to an ephemeral lifestyle, in which they spend most of the year or longer as seeds before conditions are right for a brief period of growth and reproduction. The spring ephemeral plant mouse-ear cress is a well known example. Animals can be ephemeral, with brine shrimp being an example.
Ephemeral artifacts
Ephemeral can also be used as an adjective to refer to a fast-deteriorating importance or temporary nature of an object to a person. Brands are notoriously ephemeral assets, magazine publishing was once much more ephemeral than it is today, as was television programming.
A number of art forms can be considered ephemeral because of their temporary nature. Early land art and all sand sculptures, ice sculptures and chalk drawings on footpaths are examples of ephemeral art. G. Augustine Lynas and Duthain Dealbh create ephemeral sculptures.(
Ephemeral Arts
Arts which are temporary or short lived, based on a specific occasion or event and transitory in nature.(
