How was the geologic time scale developed quizlet?
Regional SpecificsScientists first developed the geologic time scale by studying rock layers and index fossils worldwide. With this information, scientists placed Earth’s rock layers in order by relative age. Later, radioactive dating helped determine the absolute age of the divisions in the geologic time scale. How was the geologic time scale developed? The geologic time scale

Why is the ocean not homogeneous and stratified?
Regional SpecificsBecause the surface and deep ocean layers are of very different densities (due to salt content and temperature), these layers of the ocean do not mix easily. The resistance of two water bodies with different densities to mix is called stratification. Why are the oceans stratified? The ocean is stratified due to differences in density,

How are fossils classified?
Regional SpecificsFossils can be placed into four main groups based on the way they formed: impression, mineralised, trace and organic. How are fossil records classified? The interpretation of the fossil record requires describing fossils, classifying them to place them in a biological context, and determining their age to give them chronological context. Fossil classification follows the
