The Geological Time Scale (GTS) is a systematic framework that organizes Earth's history into distinct intervals based on geological and biological events. The geologic time scale is the “calendar” for events in earth history. It subdivides all time into named units of abstract time called—in...
Learn what the geologic time scale is. Identify eons, eras, periods, and epochs on the time scale, and study the history and development of the geologic time scale.Updated: 11/21/2023 What is the Geologic Time Scale? Scientists use the term geologic time to represent the 4.6 billion years...
In August of 2023 Hurricane Hilary dropped 2.2 inches of rain on Death Valley, more than the area gets in a typical year. It flooded the valley floor to depths close to a foot in places, enough to float a kayak. Folks called it the “return of Lake Manly” –the name of the lake ...

The secular trend is associated with the time scale over which the driving energy source for mantle convection changes due to radiogenic decay. Cooling histories that allow for thermal self-regulation have short reactance times relative to the decay time. Short thermal reactance times cannot lead to...

Geologic hydrogen can be generated relatively fast, and the time scale may be on the order of years or decades (Neal and Stanger 1983; McCollom and Bach 2009, Klein et al. 2013, Leong et al. 2023). Meanwhile, natural gas is stable and has lower diffusion and lower reactivity than ...
