Lab 8 dating of rocks fossils and geologic events answers

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.

Many of the largest mountain ranges and broadest zones of seismic activity come from collisions..

Comparisons of carbon ages with tree-ring data and other data for known events have allowed reliable calibration of the radiocarbon dating method.

is when an alpha particle, which consists of two protons and two neutrons, is emitted from the nucleus of an atom.

Relatively chemically inert with a hardness of 8.5.A stoney and/or metallic object from our solar system which was never incorporated into a planet and has fallen onto Earth.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.
