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.
