Debris (UK: / ˈ d ɛ b r iː, ˈ d eɪ b r iː /, US: / d ə ˈ b r iː /) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, or, as in geology, large rock fragments left by a melting glacier, etc. Depending on context, debris can refer to a number of different things.
Debris flows have volumetric sediment concentrations exceeding about 40 to 50%, and the remainder of a flow's volume consists of water. By definition, “debris” includes sediment grains with diverse shapes and sizes, commonly ranging from microscopic clay particles to great boulders.
t. e. Space debris (also known as space junk, space pollution, [1] space waste, space trash, space garbage, or cosmic debris[2]) are defunct human-made objects in space – principally in Earth orbit – which no longer serve a useful function. These include derelict spacecraft (nonfunctional spacecraft and abandoned launch vehicle stages ...
Kessler syndrome. Space debris populations seen from outside geosynchronous orbit (GSO). There are two primary debris fields: the ring of objects in GSO and the cloud of objects in low Earth orbit (LEO). The Kessler syndrome (also called the Kessler effect, [1][2] collisional cascading, or ablation cascade), proposed by NASA scientists Donald J ...
Eta Aquariids meteor shower, with zodiacal light and planets marked and labeled. A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on ...
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by ...
A rockfall in Grand Canyon National Park. Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in a moving medium, such as water, wind, or ice.
Debris might be a sci-fi show about alien technology that can defy physics, but the series is rooted in real scientific facts and theories. The post Why DEBRIS’ Science Fiction Is More Real Than ...
