The figure in section 7.1 shows the names applied to units and subunits of the Geologic Time Scale.

Using this time scale as a calendar, all events of Earth history can be placed in order without ever knowing the numerical age.

The discovery of radioactive An atom that has different number of neutrons but the same number of protons.

While most properties are based on the number of protons in an element, isotopes can have subtle changes between them, including temperature fractionation and radioactivity.

becoming known as “the Father of English Geology.” Using Steno’s principles, a relative time scale was developed in the nineteenth century with names derived from areas studied and characteristics of the rocks in those areas.

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.
