Mr. Putter and his cat Tabby are excited to participate in a library read-aloud program, but they are nervous when Mrs. Teaberry and her unpredictable dog Zeke want to join. Despite Zekeâs antics, their fears are unfounded when they discover that the event is a success for all involved.
Correlating Rock Layers correlation is the matching of rock layers from one area to another. For example, a geologist might wish to know if a layer of limestone in NY is the same layer of limestone found in MI. Correlation can be useful because valuable minerals can be found in specific layers of rock, and if we can identify the same layer far away we might be able to exploit the resource over a large area.
By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. This is called relative dating. Relative dating tells scientists if a rock layer is older or younger than another. This would also mean that fossils found in the deepest layer of rocks in an area would represent the oldest forms of life in that particular rock formation.
