If Earth's entire history could be compressed into a single year, modern humans would've appeared just 23 minutes ago! Use this DVD to introduce your students to the concept of geological time (also called deep time); relative age dating of rock via the principles of stratigraphic superposition, original horizontality, and cross-cutting; absolute age dating by radioactive decay; the chemical elements, heavy and light, that make up the planet; and Earth's three main layers: crust, mantle and core.

Format DVD, 23 mins.
