Review of Short Phrases and Links|
This Review contains major "Rheid"- related terms, short phrases and links grouped together in the form of Encyclopedia article.
- A rheid is a material which when below its melting point will deform 1000 times more that under elastic deformation for the same conditions.
- In geology, solid Earth materials that exhibit viscous flow over long time scales are known as rheid s.
- In geology, a rheid is a solid material that deforms by viscous flow.
- Halite, the mineral form of salt, is a geological material that behaves as a rheid over relatively short time periods.
- See also Rheology Viscoelasticity External links Definition of rheid --This geology article is a stub.
- To be considered a rheid, deformation by flow should exceed elastic deformation by at least a factor of three.
- The similar term "diapir" from dia-peirein, "to pierce through" is reserved for a piercement in which rheid flow is important.
- Since the mantle is known to be solid (it supports the propagation of shear waves), it must be behaving as a rheid.
- At the temperature and pressure of the mantle, rocks are sufficiently rheid that convection currents can be maintained.
- Types of rheids Almost any type of rock can behave as a rheid under appropriate conditions of temperature and pressure.
- It uses material from the "Rheid".
