Submarine volcano – Underwater vents or fissures in the Earth's surface from which magma can erupt; Summit – Point on a surface with a higher elevation than all immediately adjacent points; Supervolcano – Volcano that has had an eruption with a volcanic explosivity index (VEI) of 8; Surge channel – Type of coastal landform
The top image shows asperities under no load. The bottom image depicts the same surface after applying a load. In materials science, asperity, defined as "unevenness of surface, roughness, ruggedness" (from the Latin asper—"rough" [1]), has implications (for example) in physics and seismology. Smooth surfaces, even those polished to a mirror ...
These formulas are identical in the sense that the formula for S oblate can be used to calculate the surface area of a prolate spheroid and vice versa. However, e then becomes imaginary and can no longer directly be identified with the eccentricity. Both of these results may be cast into many other forms using standard mathematical identities ...
A stream flowing in a direction approximately opposite to that of the dip of the underlying surface rocks. It is frequently, though not necessarily, an obsequent stream. [4] anticline A geological upfold that has an arch-like convex shape and its oldest beds near its center, often visible at the Earth's surface in exposed rock strata. Contrast ...
A parting and contraction of the glaze on the surface of ceramic ware during drying or firing, resulting in unglazed areas bordered by coalesced glaze. May be caused by uneven glazing, excessive glaze thickness or a greasy substrate. [8] Crazing A glaze fault characterised by the cracking of fired glazes and due to high tensile stresses.
Many of the terms are not restricted to refer to features of the planet Earth, and can be used to describe surface features of other planets and similar objects in the Universe. Examples are mountains, hills, polar caps, and valleys, which are found on all of the terrestrial planets. The scientific study of landforms is known as geomorphology.
Monkey saddle (saddle-like surface for 3 legs.) Torus; Dupin cyclide (inversion of a torus) Whitney umbrella; Miscellaneous surfaces. Boy's surface. Boy's surface;
In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.
