The theory that the outer layer of the Earth (the lithosphere) is broken in several plates, and these plates move relative to one another, causing the major topographic features of Earth (e.g.mountains, oceans) and most earthquakes and volcanoes.Using this time scale, geologists can place all events of Earth history in order without ever knowing their numerical ages.The specific events within Earth history are discussed in Chapter 8.

Meteorite is used for the rock on Earth, meteoroid for the object in space, and meteor as the object travels in Earth's atmosphere.This can be further calculated for a series of half-lives as shown in the table.The table does not show more than 10 half-lives because after about 10 half-lives, the amount of remaining parent is so small it becomes too difficult to accurately measure via chemical analysis.The pinching Temple Butte is the easiest to see the erosion, but even between the Muav and Redwall, there is an Wikimedia Commons' src=" alt="The rocks are mostly red." width="300" height="224" srcset=" sizes="(max-width: 300px) 85vw, 300px"/Meaning "visible life," the most recent eon in Earth's history, starting at 541 million years ago and extending through the present.Known for the diversification and evolution of life, along with the formation of Pangea.
