British: Gastro-oesophageal reflux disease (GORD); [1] gastric reflux disease, acid reflux disease, reflux, gastroesophageal reflux: X-ray showing radiocontrast from the stomach (white material below diaphragm) entering the esophagus (three vertical collections of white material in the mid-line of the chest) due to severe reflux: Pronunciation
In surface erosion, the material only degrades on the surface which causes the material to “shed off” its surface over time. In bulk erosion, the material loses volume throughout equally, which is represented by the fading colors. Surface and bulk erosion are two different forms of erosion that describe how a degrading polymer erodes. In ...
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
River erosion can be driven by tectonic uplift, climate, or potentially both mechanisms. It is difficult in many areas, however, to decisively pinpoint whether tectonism or climate change can individually drive tectonic uplift, enhanced erosion, and therefore terrace formation. In many cases, simplifying the geologic issue to tectonic-driven vs ...
A solution proposed by Enbridge to prevent further erosion in the Bad River along Line 5 is still awaiting approval from the Bad River Band as winter approaches.
Shoreline erosion, which occurs on both exposed and sheltered coasts, primarily occurs through the action of currents and waves but sea level (tidal) change can also play a role. Sea-dune erosion at Talacre beach, Wales. Hydraulic action takes place when the air in a joint is suddenly compressed by a wave closing the entrance of the joint. This ...
Fault-line scarps are typically formed due to the differential erosion of weaker rocks along a fault. Such erosion, occurring over long time periods, may shift a physical cliff far from the actual fault location, which may be buried beneath a talus, alluvial fan or filled-in valley sediments. It may therefore be difficult to distinguish between ...
Diagram of accretion and erosion of sediments in a coastal system. Black arrows indicate accretion, and white arrows indicate erosion. Sedimentary budgets are a coastal management tool used to analyze and describe the different sediment inputs (sources) and outputs (sinks) on the coasts, which is used to predict morphological change in any particular coastline over time.
