How does lenticular bedding form?

Lenticular bedding is a sedimentary bedding pattern displaying alternating layers of mud and sand. Formed during periods of slack water, mud suspended in the water is deposited on top of small formations of sand once the water's velocity has reached zero.

Likewise, how is a bedding plane formed?

Carboniferous limestone is a sedimentary rock formed in the Yorkshire Dales around 300 million years ago. The bedding planes are the horizontal layers formed as the rocks were compressed under deposits formed above.

How is Flaser bedding formed?

Flaser beds are a sedimentary, bi-directional, bedding pattern created when a sediment is exposed to intermittent flows, leading to alternating sand and mud layers. While flaser beds typically form in tidal environments, they can (rarely) form in fluvial conditions - on point bars or in ephemeral streams.

How graded bedding is formed?

In geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer ones.
