What is the gradual eating away of a metal called?
Corrosion. This often involves a reaction with oxygen.
The gradual wearing away of metals due to chemical reactions is called "corrosion"
Gradualism is the policy of gradual reform rather than sudden change or revolution; in biology, the theory that evolution occurs slowly but steadily rather than abruptly.
Corrosion the answer is corrosion
In musical notation the word "crescendo" refers to a passage of music during which the volume gradually increases.
Mostly yes apart from very unreactive metals like lead or gold. If M is the metal and HX is the Acid the equation looks like: 2M + 2HX = 2MX + H2
Crescendo and diminuendo
Hot material ascends at the ridge axis form the mantle. It partially melts. The basaltic melts ascend and form 6-7 km of oceanic crust. The seafloor and the underlying mantle …then move away from the ridge axis. The material cools from top down. As it does it contracts thermally and becomes more dense. The vertical contraction of the material and the increased load on the underlying mantle causes the seafloor to subside. The weight of the overlying water also causes subsidence. To the first order, the predicted depth to the seafloor increases with the square root of age from the ridge axis. This in fact occurs and was strong evidence for the reality of seafloor spreading in the late 1960s. Note that Lord Kelvin was on the trans-Atlantic cable project. He crossed the Charlie-Gibbs fracture zone rather than the ridge axis. The square-root relationship was not evident. Wegener also considered the process to some extent, but ended up with continents moving as rafts rather than with seafloor spreading.

The "goal" of every element is to complete its octet (unless it's already complete like the Noble Gases). To do so, or to achieve a more stable electron configuration, it wil…l either donate or accept neighboring electrons.
a WHO cannot eat through metal but a WHAT can and that WHAT is Hydroflouric acid. Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water.
