What is transitional slide?
A slide transition is how one slide is removed from the screen and the next slide is displayed during a presentation. From this group choose a special effect to be applied during the transition between the previous slide to the next slide.
How does a translational slide occur?
Translational slides Such slumps and slides occur in very wet weather, when the near-surface soil and rock debris gets saturated with water, and slides and flows downslope.
What is the difference between rotational slides and translational slides?
Rotational slides commonly show slow movement along a curved rupture surface. Translational slides often are rapid movements along a plane of distinct weakness between the overlying slide material and the more stable underlying material.
What is the difference between a slump and a translational slide?
Slumps or rotational slides have curved slip surfaces, and tend to produce small topographic benches, which may rotate and tilt in an up‐slope direction. Translational slides generally have planar slip surfaces, and materials moves along inclined slip planes within and parallel to a slope.
What is a translational slide?
Translational slides A translational or planar landslide is a downslope movement of material that occurs along a distinctive planar surface of weakness such as a fault, joint or bedding plane. These landslides occur at all scales and are not self-stabilising. They can be very rapid where discontinuities are steep.
What is a debris slide?
: a mass of predominantly unconsolidated and incoherent soil and rock fragments that has slid or rolled rapidly down a steep slope when comparatively dry to form an irregular hummocky deposit — compare debris-avalanche.
Is an example of a translational slide?
Examples of translational landslides in two different regions: a sliding of weathered metamorphic materials, Chiapas, southern Mexico; b translational slide in volcanic scoria cones, central Mexico.
What are translational slides?
Translational slides A translational or planar landslide is a downslope movement of material that occurs along a distinctive planar surface of weakness such as a fault, joint or bedding plane. Some of the largest and most damaging landslides on Earth are translational.
What is translational failure?
Source: Roadside. a slide mass that displaces along a planar or undulating surface of rupture and slides out over the original ground surface. Translational slides frequently grade into flows or spreads.
Is a slump fast or slow?
The speed of slump varies widely, ranging from meters per second, to meters per year. Sudden slumps usually occur after earthquakes or heavy continuing rains, and can stabilize within a few hours. Most slumps develop over comparatively longer periods, taking months or years to reach stability.
What is slide geology?
A slide happens when a section of soil or rock suddenly gives way and moves down a slope. The material moves as a single mass along a slippery zone. The slippery zone is often made up of wet sediment .
What is a translational landslide?
A translational or planar landslide is a downslope movement of material that occurs along a distinctive planar surface of weakness such as a fault, joint or bedding plane. Some of the largest and most damaging landslides on Earth are translational.
How is a rotational landslide different from a translational landslide?
Rotational landslide is the downward and outward movement of a mass on top of a concave upward failure surface (Abbott 2004). Source: Hatfield Translational Landslides Translational landslide is a mass that slides downward and outward on top of an inclined planar surface (Abbott 2004).
How is a block slide different from a landslide?
Translational slide: In this type of slide, the landslide mass moves along a roughly planar surface with little rotation or backward tilting (fig. 3B). A block slide is a translational slide in which the moving mass consists of a single unit or a few closely related units that move downslope as a relatively coherent mass (fig. 3C).
Which is the best description of a rotational slide?
Rotational slide: This is a slide in which the surface of rupture is curved concavely upward and the slide movement is roughly rotational about an axis that is parallel to the ground surface and transverse across the slide (fig. 3A).
What causes separation and movement in a landslide?
Separation occurs along discontinuities such as fractures, joints, and bedding planes, and movement occurs by free-fall, bouncing, and rolling. Falls are strongly influenced by gravity, mechanical weathering, and the presence of interstitial water.
