Document Summary

Rocks are different depending on the time or area in which they formed. Scotland used to be hot and arid - 350 million years ago. Oman used to be covered in ice - 600-700 million years ago. Determine where rocks will be destroyed by erosion. Works in conjunction with topography generated by plate tectonics. Climate is also a large factor in formation and destruction of sedimentary rocks. Global (eustatic) sea level is also controlled by the climate. Record of global-scale changes in the earth"s life. Includes layered rocks that have not been fed to a plate boundary yet. A sequence of rock units in an area can reflect the geological changes. The area is divided into a series of formations which show the changes. Older units are almost always below younger units. Formations can be affected by later events like: Can cut through rock they are injected into. Fragments of rock within a different rock must be older.
