WebFigure 5.4. 1: Horizontal strata in southern Utah. The most basic sedimentary structure is bedding planes, the planes that separate the layers or strata in sedimentary and some volcanic rocks. Visible in exposed outcroppings, each bedding plane indicates a change in sediment deposition conditions. This change may be subtle. WebThe laws of stratigraphy, developed in geology, have long been adopted for archaeological use. Archaeological excavation in the UK relies on the application of these principles to define, interpret and understand site history.

WebMeandering Rivers are located on flat terrain that reduces the flow speed of water, allowing the river to curve or "meander". The bends in the river will migrate back and forth within the river valley. There is a differentiation in flow speeds within a meandering river channel that produces areas of erosion and deposition.
