the name 'sial' was taken from the first two letters of silica and of alumina. the sial is often contrasted to the 'sima,' the next lower layer in the earth, which is often exposed in the ocean basins; and the nickel-iron alloy core, sometimes referred to as the "nife". these geochemical divisions of the earth's interior (with these names) were first proposed by eduard suess in the 19th century. this model of the outer layers of the earth has been confirmed by petrographic, gravimetric, and seismic evidence.
