Non horizontal deposition of sediments due to wind or water currents; found in sand dunes, river channels and deltas
Size: 12 cm

Particles gradually change in size from coarse sand particles on the bottom to finer silt particles at the top of the sediment sequence indicating a gradual change of transport conditions during deposition from a high-energy to a low-energy environment.

Soft-sediment deformation where the load of massive sand on less dense mud causes the formation of casts
Size: 8 cm

undulations of the sediment surface produced as wind or water currents move across the sediment
Size: 15 cm

Indicate the direction of currents at the time of deposition
Size: 20 cm

Ridges form at right angle to the direction of motion with the steeper side in the down current direction
Size: 10 cm

Formed in shallow lakes and desert basins when mud is exposed to air, dries out and shrinks, forming cracks
Size: 15 cm

Circular pits on the sediment surface produced by the impact of raindrops when the sediment was still soft
Size: 7 cm
