	Cross Bedding	Graded Bedding
1	The particles are Vertically sorted.	The particles are horizontally sorted.
2	Cross-bedding in a sandstone that was originally deposited by rivers. The deposition currents were flowing from right to left	Once it reaches the flat deep sea regions, it slows down due to friction, and gradually the sediment settles out of suspension. Larger grain sizes settle out first, and then successively smaller ones.
3	Cross-bedding can also be produced when wind blows over a sand surface and creates sand dunes.	Largest grains occur at the base, and the grain size gradually decreases.
4	This type of bedding is also called current bedding.	This type of bedding is commonly associated with so called turbidity currents
