GEOL 5460 - Earth Systems Evolution


Synthesis of the coupled histories of the Earth’s interior, surface, and life.

Requisites:
Credit Hours: 4
Repeat/Retake Information: May not be retaken.
Lecture/Lab Hours: 2.0 lecture, 2.0 laboratory
Grades: Eligible Grades: A-F,WP,WF,WN,FN,AU,I
Learning Outcomes:
  • Know the evidence for an oxygen-free early atmosphere. Understand how, when, and why Earth’s atmosphere became oxygenated, and the timing and cause(s) of subsequent changes in atmospheric oxygen levels.
  • Understand how the biogeochemical cycles of carbon, silica, and sulfur have evolved through Earth history.
  • Understand the Greenhouse climate planetary state and the connections between silicate weathering and carbon burial that allowed that state to be the dominant one in the Phanerozoic.
  • Understand the Hothouse climate planetary state and the connections between intense volcanism and the forcing of that climate state in the Phanerozoic and pre-Phanerozoic.
  • Understand the Icehouse climate planetary state and the connections between silicate weathering and carbon burial that forces that state.
  • Understand the fundamental interconnections between land, sea floor, ocean water, and the atmosphere, and how changes in those relationships have shaped changes in Earth’s atmosphere and climate.
  • Understand the fundamental tectonic differences between the geology of Archean and Proterozoic rocks.
  • Understand the origin and significance of Banded Iron Formations and why the seas in which they formed gave way to sulfidic Canfield ocean.
