A large statistical population of measurements obtained from moraine and rock glacier surfaces was used to analyze the variability of mean R-values in the same lithology and overall southern valley exposition.Four separate sets of glacial/periglacial morphosystems are present at different positions in the Western Tatras starting from valley outlets to the highest cirques, which represent successive phases of deglaciation.
The key question is how robust this is over a larger sample.
R-value means and 95% confidence intervals for selected Last Glacial Maximum (LGM), and Late Glacial (LG-1, LG-2 and LG-3) stages (respectively, 40.1 ± 1.1, 46 ± 0.5, 53.5 ± 1.0 and 60.5 ± 0.3) are significantly statistically different and values for each age category are comparable for the two analyzed valleys.
The results of weathering indexes used in conjunction with geomorphological relationships were taken together to reconstruct the pattern of deglaciation on southern Tatra slopes.
Stratigraphic Superposition - Because of Earth's gravity, deposition of sediment will occur depositing older layers first followed by successively younger layers.
Thus, in a sequence of layers that have not been overturned by a later deformational event, the oldest layers will be on the bottom.
To better understand these concepts, let's look at an archeological example: Imagine we are a group of archeologists studying two different trash pits recently discovered.
Nelson Tulane University In order to understand how geologists deal with time we first need to understand the concepts of relative age and absolute age.
: When using a compound microscope this term refers to the thickness of the subject that is in focus.
The Elodea leaf is composed of two layers of cells.
deals with all the physicochemical aspects of life.
The modern tendency toward cross-disciplinary research and the unification of scientific knowledge and investigation from different fields has resulted in significant overlap of the field of biology with other scientific disciplines.
biology deals with groups or populations of organisms that inhabit a given area or region.
