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.
Relative dating observes the placement of fossils and rock in layers known as strata. Basically, fossils and rock found in lower strata are older than those found in higher strata because lower objects must have been deposited first, while higher objects were deposited last.
