Bedforms (Ripples and Dunes)
Centimeter to meter-scale layering, or bedding, is a defining characteristic of sedimentary rocks. Non-horizontal depositional beds are called bedforms, and geologists ref...

Sedimentation
Sediments are loose Earth materials such as sand that accumulate on the land surface, in river and lakebeds, and on the ocean floor. Sediments form by weathering of rock. They then erode...
