Based on flow models, the variation of oxygen isotopes, the concentration of carbon dioxide in trapped air bubbles, the presence of oxygen isotopes, acid concentrations, and particulates, they believe the lowest layers of the ice sheets were laid down over 160,000 years ago.Annual oscillations of such quantities are often evident in the record. Do they cause a problem for the recent-creation model of earth history? This article will show that the great ages reported for the bottom layers of ice sheets depend on assumed models of past climate and are not the result of direct counting of layers.Certain layers are in the form of sand bars and gravel banks - rock debris spread over the land by streams.Some rocks were once lava flows or beds of cinders and ash thrown out of ancient volcanoes; others are portions of large masses of once-molten rock that cooled very slowly far beneath the Earth's surface.
The argument may be compared to filling a barrel which has numerous small holes in its sides.
An alternative model of recent glacier formation following the Flood described in Genesis will be suggested.
The Greenland Society of Atlanta has recently attempted to excavate a 10-foot diameter shaft in the Greenland ice pack to remove two B-17 Flying Fortresses and six P-38 Lightning fighters trapped under an estimated 250 feet of ice for almost 50 years (Bloomberg, 1989).
The barrel represents the earth's atmosphere in which the carbon-14 accumulates.
The water leaking out the sides of the barrel represents the loss (mainly by radioactive decay) of the atmosphere's supply of carbon-14.
PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.
