Geology Photo of the Week #42

Matt Herod July 6, 2015

This week’s photo is a beautiful example of geochemistry in action. Briefly, travertine, which is composed of CaCO3 is often precipitated at hot springs as they emerge from the ground forming these gorgeous terraces. The reason for their formation is Henry’s gas law in action which states “the solubility of a gas in a liquid is directly proportional to the partial pressure of the ...[Read More]

About

The term geosphere is an all-encompassing word that incorporates just about every aspect of the earth sciences. This means that topics ranging from geophysics to geochemistry to geobiology are part of the geosphere. The blog Geosphere honours its namesake by covering any and every topic in the geosciences. The principal goal of Geosphere and its author, Matt Herod, is to make science clear for anyone that should stumble in and enhance awareness of the geosphere for all. With this in mind I encourage any who have questions to post, comment or email me.
