Determining Geologic Time  Many geologic events that Earth Scientists study occurred millions of years ago. The ages of these events can be determined.

By Michael Nau and Elizabeth Dorsey. Weathering vs. Erosion  Erosion involves movement and weathering does not.  Weathering is the main agent in erosion.

Sediment in Motion. Weathering The process by which rock is broken down (physical or chemical)

What is Erosion and How is it Different than Weathering  Weathering is the breaking down of rock into smaller pieces.  Erosion is the MOVEMENT of these.

Laws of Geologic History. Law of Superposition The oldest layer is at the bottom and the youngest layer is at the top. The oldest layer is at the bottom.

Relative Dating. Relative Dating is one of the methods that geologists use to help tell geologic time. It can NOT tell us exactly how old something is,

Relative-Age Dating. Scientists have not always thought Earth was as old as it is. James Hutton in the late 1700’s was the first geologist to think Earth.

 Weathering – breaking down rock into smaller pieces chemically and physically.  Erosion- carrying away the particles and depositing them.  Glaciers.

Photo taken 8/2/08 in Ocean Beach, California Features which aid in the process of relative dating: This photo features an unconformity And inclusions An unconformity is created when deposition ceases and then is followed by a long period of erosion. Then when deposition continues the new sediments are deposited upon the eroded landscape. The result of this process is an unconformity. (Tarbuck & Lutgens, 2008) Often when one sedimentary layer is laid upon another it will surround broken off fragments of the existing rock layer enclosing them within. This is Known as an inclusion. (Tarbuck & Lutgens, 2008)
