Records from Lake Magadi, Kenya, suggest environmental variability driven by changes in Earth’s orbit

via Records from Lake Magadi, Kenya, suggest environmental variability driven by changes in Earth’s orbit Boulder, Colo., USA: Rift Valley lakes within eastern Africa range from freshwater to highly alkaline systems and are homes to diverse ecosystems. These Rift Valley lakes are also sedimentary repositories, yielding a high-resolution environmental record that can be targeted to… Continue reading Records from Lake Magadi, Kenya, suggest environmental variability driven by changes in Earth’s orbit

Understanding Earth Fissures: A Man-Made Geohazard

https://www.youtube.com/watch?v=1SXaMH8gV6I Earth fissures are long, narrow cracks in the ground that form where the ground is sinking. They can erode very quickly, posing a hazard to nearby infrastructure. In Arizona, land subsidence--the sinking of the earth--is caused by groundwater withdrawal, meaning that earth fissures are a man-made--or anthropogenic--hazard. This video that I made as part… Continue reading Understanding Earth Fissures: A Man-Made Geohazard
