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.
Compression Stress. Compression is a type of stress that causes the rocks to push or squeeze against one another. It targets the center of the rock and can cause either horizontal or vertical orientation. In horizontal compression stress, the crust can thicken or shorten. In vertical compression stress, the crust can thin out or break off. The force of compression can push rocks together or cause the edges of each plate colliding to rise.
