Earth

Plate tectonics and other earth processes drive volcanism, earthquakes, and the formation of mid-ocean ridges that change the face of the planet. CEOE researchers study Earth’s geology and its complex interactions with biological and chemical aspects of the environment.

Cracks in the seafloor at hydrothermal vents are rich in minerals, for example, and play a role in the cycling of iron and other elements worldwide. Microbes living within the earth are an emerging topic of study in areas where water saturates the sediment, from the bottom of the ocean to small inland streams.

Researchers studying these types of phenomena require integrative knowledge of the chemical, physical, and biological processes above, on, and below the earth’s surface.

Digging deeper

Many CEOE scientists examining this theme of focus are affiliated with the Department of Geological Sciences, where focus areas include geomicrobiology, geochemistry, earth history, and stratigraphy.
