How does the geologic timescale fit with the view of a young earth?
” Answer: The question of how the geologic timescale fits with the young earth view is a good one. The Earths crust is made up of three different kinds of rock: igneous and metamorphic rock, both of which were once in a molten or semi-molten state, and sedimentary rock, rock which once existed elsewhere but was re-deposited as sediments in its current location. Sedimentary rock is usually found to be layered. These layers are called strata. Strata layers often contain the fossilized remains of plant and animal life which were buried and subsequently preserved through fossilization. Certain fossils have been found to be unique to certain layers. These fossils are called index fossils. Paleontologists use index fossils to identify the rock layers in which they are found. If an index fossil is thought to be 70 million years old, then the rock layer in which it was found must also be 70 million years old. The Geologic Column is a sequential catalog of these layers, the fossils they contain
