Wave-formed ripple Wave-formed ripple In sedimentology, wave-formed ripples or wave-formed ripple marks are a feature of sediments (sandstones, limestones, siltstones) and dunes. These ripple marks are often characterised (and thus distinguished from current ripples) by symmetric cross sections and long relatively straight crests, which may commonly bifurcate. Commonly, these crests can be truncated by subsequent flows. Their wavelength (periodicity) depends on the sediment grain size, water depth and water-particle orbits in the waves. On tidal flats the pattern of wave-formed ripples may be complicated, as a product of changing depth and wind and tidal runoff directions. Symmetrical ripples are commonly found in
Regular sound correspondences between Hungarian and other Uralic languages Regular sound correspondences between Hungarian and other Uralic languages There are numerous regular sound correspondences between Hungarian and the other Uralic languages. For example, Hungarian "á" corresponds to Khanty "o" in certain positions, and Hungarian "h" corresponds to Khanty "x", while Hungarian final "z" corresponds to Khanty final "t". These can be seen in Hungarian "ház" ("house") and Khanty "xot" ("house"), or Hungarian "száz" ("hundred") and Khanty "sot" ("hundred"). Hungarian and Khanty are closely connected, either genealogically or as part of a language area. The distance between Hungarian and the Finnic languages is greater, but the correspondences are also regular.
