BEDDING PLANE: A surface parallel to the surface of deposition, which may or may not have a physical expression. The original attitude of a bedding plane should not be assumed to have been horizontal. See also CROSS-BEDDING.

Heaviest (largest) clasts drop out first, smallest clasts drop out last b) Cross-bedding: formed in cohesionless sediment (e.g. sand), by migration of dunes in direction of current. Sand grains bounce up windward side of dune, cascade down leeward side, forming cross bedding.
