The #Cretaceous hothouse had atmospheric #CO₂ levels above 1,000 ppm, compared with 420 today, and temperatures up to 10℃ higher than today. It was caused by very fast-moving #tectonic plates, which increased CO₂ emissions. Tectonic plates slow down due to collisions, which leads to mountain building. The weathering of igneous rocks is very efficient in reducing atmospheric CO₂. Spreading olivine on beaches could absorb up to a trillion tonnes of CO₂ from the atmosphere https://www.sydney.edu.au/news-opinion/news/2022/05/26/how-plate-tectonics-have-maintained-earth-s--goldilocks--climate.html
@nationalparks #PointReyes #NationalSeashore is a #nationalpark near San Francisco established in 1962 by John F. Kennedy. The area encompasses a #peninsula and a small section of the adjacent ocean. It is of #tectonic interest because it lies on the #PacificPlate, which moves relative to the #NorthAmericanPlate with the San Andreas Fault between both. The peninsula has a special vegetation: the #Californiacoastalprairie.

Scientific FrontlineAncient subduction zones—regions where #tectonic plates historically collided and forced material beneath one another—are the primary drivers behind the formation and distribution of critical rare earth element (REE) deposits and carbonatite magmas.

#TheGreatUnconformity — a gap in Earth’s #geologicalrecord. New research suggests it was created by shifting continents, rather than “#SnowballEarth” or #Cambrian life. Evidence that the gap was largely created by #tectonic processes that occurred from 2.1B to 1.6B years ago, in the #Neoproterozoic era, during the formation of an ancient supercontinent called Columbia

CBC Top StoriesThe ‘Big One’ just got more complicated
Scientists have discovered a massive tear in the tectonic plate off the coast of Vancouver Island. This "rip" suggests that the northern end of the Cascadia Subduction Zone is actually starting to shut down. The CBC’s Johanna Wagstaffe investigates what this discovery might mean for the "Big One" off the coast of Vancouver Island.

Scientists discover recent tectonic activity on the moon
Scientists have produced the first global map and analysis of small mare ridges (SMRs) on the moon, a characteristic geological feature of tectonic activity. Published in The Planetary Science Journal Dec. 24, 2025, the analysis performed by scientists at the National Air and Space Museum's Center for Earth and Planetary Studies and colleagues reveals for the first time that SMRs are geologically young and are widespread across the lunar maria—the vast, dark plains on the moon's surface. The team's discovery of how SMRs form introduces a new set of potential moonquake sources that could affect future site selections for lunar landings.
