If the analyses are carried out in order to offer a steady profile downward from the surface in sufficient element to permit interpretation, counting of annual layers results in an absolute time scale alongside the core. The necessary diploma of detail to be studied relies upon after all on the thickness of the annual layers and on the regularity of the cycles, the criterion being that no new vital function seems in the profile when the ice core is studied in further element. Here, we centered on the identification of seasonal patterns in the ionic and
horizons provided by traditionally known volcanic eruptions. The obtained age

Then, to the far left of the graph, a speedy rise in temperature again because 
the mud settles down and the temperatures and thus the pressures have additionally settled. The earth warms once more and the ices soften, leaving what’s left on the poles. You see, if one does not presume lengthy ages, many speedy storms in a time of fluctuating temperatures and world upheaval can account for what we see in that graph. Approximately 98 per cent of the Antarctic continent is covered by the ice sheet which is on common about 2,500 metres thick and, at it’s deepest location, four,seven hundred metres thick. It is as a outcome of of this thick ice mass that Antarctica is, on average, the highest continent.
