The layers of rock are known x vediocam take dirty sex "strata", and the study of their succession is known as "stratigraphy". Fundamental to stratigraphy are a set of simple principles, based on elementary geometry, empirical observation of the way these rocks are deposited today, and gravity. In x vediocam take dirty sex situation, the cave contents are younger than both the bedrock below the cave and the suspended roof above. The simplest situation for a geologist is a "layer cake" succession of sedimentary or extrusive igneous rock units arranged in nearly horizontal layers.

In such a situation, the "principle of superposition" is easily applied, and the strata towards the bottom are older, those towards the top are younger. In order for a layer of material to be deposited, something has to x vediocam take dirty sex beneath it to support it. This document is partly based on a prior posting composed in reply to Ted Holden.

My thanks to both him and other critics for motivating me. Many other indicators are commonly present, including ones that can even tell you the angle of the depositional surface at the time "geopetal structures""assuming" that gravity was "down" at the time, which isn't much of an assumption In more complicated situations, like in a mountain belt, there are often faults, folds, and other structural complications that have deformed and "chopped up" the original stratigraphy.

It can't float in mid-air, particularly if the material involved is sand, mud, or molten rock. Notify me of followup comments via e-mail.

An early summary of them is found in Charles Lyell's. In no way are they meant to imply there are no exceptions. For example, the principle of superposition is based, fundamentally, on gravity.
