The slumping method is a glass forming … WebbAs these displacements can be linked directly to a slumping process, they can easily be used to indicate areas of active mass transport on lateral moraines. It is difficult to quantify the importance of fast processes such as debris flows, rockfall of individual large boulders and landslides on the moraine.
A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. Causes of slumping include earthquake shocks, thorough wetting, freezing and thawing, undercutting, and loading of a slope. Webbslumping process. Based on major discoveries of recent and previous X-ray astronomy space missions, all major space agencies consider future missions with imaging X-ray telescopes onboard. Future large space X-ray telescopes (such as IXO/XEUS considered by ESA13 or IXO/Constellation X by NASA) require precise and light-weight X-ray
WebbWhen slumping by gravity, thin glass is heated and reshaped under its own weight. This process is particularly suitable for higher material thicknesses with low degrees of deformation.

This rheology is adopted to quantify...
WebbSlumping occurs when material moves along a curved path. The technical term is ‘rotation’ so slumping is also known as ‘rotational slip’ or ‘rotational slump’. In the photograph the path of the slump is highlighted by the red line. It occurs mainly in soft and uniform rocks such as silts and clays, and can be triggered by heavy rain.
