It represents the foot of the cliff preserved at and below the level of water table. If there is a tectonic uplift of the coast, these abrasion platforms can be raised to form coastal terraces, from which the amount of uplift can be calculated from their elevation relative to the sea level, taking into account any eustatic sea level changes. On ...
Abrasion, under its strictest definition, is commonly confused with attrition and sometimes hydraulic action however, the latter less commonly so. Both abrasion and attrition refers to the wearing down of an object. Abrasion occurs as a result of two surfaces rubbing against each other, resulting in the wearing down of one or both of the surfaces.
Wave-cut platform at Southerndown, South Wales, UK. A wave-cut platform, shore platform, coastal bench, or wave-cut cliff is the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by erosion. Wave-cut platforms are often most obvious at low tide when they become visible as huge ...
A raised beach, coastal terrace, [1] or perched coastline is a relatively flat, horizontal or gently inclined surface of marine origin, [2] mostly an old abrasion platform which has been lifted out of the sphere of wave activity (sometimes called "tread").

Home Depot’s viral 12-foot skeleton lives up to the hype. Its oversized design makes for an eye-catching Halloween display, and once assembled, it’s surprisingly stable considering its size. Pros
One type of instrument used to get the abrasion rate and normalized abrasion rate is the abrasion scrub tester, which is made up of a mechanical arm, liquid pump, and programmable electronics. The machine draws the mechanical arm with attached brush (or sandpaper, sponge, etc.) over the surface of the material that is being tested.
After horses were introduced to North America, many Plains Indian tribes began to make larger horse-drawn travois. Instead of making specially constructed travois sleds, they would simply cross a pair of tepee poles across the horse's back and attach a burden platform between the poles behind the horse. This served two purposes at once, as the ...
