Saltation – Particles bouncing along the sea bed (bouncing is the important word)

Too much salt was killing the nation (saltation), so the government ordered all salt pots to be bounced into the sea.

Saltation occurs when water flow – waves or current – is sufficient to repeatedly lift particles from the seabed, bouncing them along.

Over time, saltation can result in large deposits of sand and shingle – it is one of the ways in which beaches are formed.
