GEOL 200 and GEOL 201 or equivalent. Students should feel comfortable with the manipulation of algebraic equations and have a rudimentary knowledge of single-variable differential calculus. Where applied, chemical principles essential for the course are adequately explained, although it would be beneficial for students to have CHEM 217.
Geology 415: Earth’s Origin and Early Evolution explores the evidence for the various processes, events, and materials involved in the formation and evolution of Earth. The course also describes various geochemical tools and techniques used by geologists to reveal and interpret the evidence.
Outline
Unit 1: Earth in the Solar System
Unit 2: Geochemical Tools and the Origin of the Elements
Unit 3: Meteorites
Unit 4: The Origins of Stars and the Solar System
Unit 5: The Internal Structure and Composition of Earth
Learning outcomes
Upon successful completion of this course, you should be able to
describe Kepler’s laws of motion and outline how they relate to Newton’s laws.
list the planets in the solar system in order of their distance from the sun and outline describe their composition.
describe, compare, and contrast asteroids and comets and explain how the physical and chemical characteristics of meteorites provide information about conditions in the early solar system.
explain how the elements that compose the solar system, Earth, and its organisms originated.
describe the distinguishing geological features of the terrestrial planets.
explain how the age of the Earth is known and describe the Rb-Sr, Sm-Nd, and U-Pb isotope systems and how they can be used for dating geological events.
using the nebular hypothesis, describe how the young solar system including planets emerged and evolved.
explain the process of differentiation and core formation on Earth and outline why C1 chondrites do not appear to be the building blocks of the Earth.
sketch the structure of the mantle, explain the seismic discontinuities within the mantle, and outline major events in the early history of the mantle.
explain the origins of early continental crust and describe how it differs from younger continental crust.
