in sedimentary rock: Wackes. The most widespread internal structure of wackes is graded bedding, although some sequences display it poorly. Sets of cross strata more than three centimetres thick are rare, but thinner sets are very common. Parallel lamination is widespread, and convolute bedding is usually present. These internal structures are arranged within wacke beds in aâ¦

United's new Embraer 170 jets have 18.25-wide seats, and JetBlue's planes have 17.8-wide seats.
