Bedding is a fundamental feature of sedimentary rocks, where layers of sediment are deposited in horizontal sheets. These layers, or beds, are parallel to each other and to the surface on which they were deposited. This layering is caused by changes in the type of sediment being deposited, the rate of deposition, or other environmental factors.

Here are some other terms that relate to bedding:

* Stratification: A general term for the layering of sedimentary rocks, including bedding and other forms of layering.

* Foliation: A type of layering found in metamorphic rocks, where minerals are aligned parallel to each other due to pressure.

* Joint: A fracture in rock that doesn't involve movement along the fracture surface. While not directly related to bedding, joints can sometimes occur parallel to bedding planes.
