Introduction to Earth System Science
Clark Atlanta University - University with graduate programs, including doctoral programs
Course provides a scientific understanding of the physical earth system - lithosphere, hydrosphere, atmosphere, solar system - by describing how its component parts and their interactions have evolved, how they function, and how they may be expected to continue to evolve on all time scales. Students are required to attend a two-hour laboratory each week. This course can be used to satisfy the core physical science requirement for all non-science majors.
Student will develop the following skills:
1. To distinguish internal from external earth processes on the basis of energy source.
2. To analyze earth system problems and solve them through the use of lower mathematics.
3. To synthesize information from maps, graphs, images, and tables to answer earth system questions, verify text explanations, and draw conclusions.
Specific learning outcomes:
1. Ability to classify earth system processes as either solar driven or geothermal driven.
2. Ability to use common logarithms, exponentials, elementary dimensional analysis, proportions/ratios, linear relationships, power law relationships, algebra, stress/strain relationships, and elements of trigonometry to determine earth system metrics such as earthquake magnitude and location, composition of the global water resource, conversion of river discharge units, river and seafloor gradients, calculations involving river competence, difference between brittle and ductile behavior, calculation of stellar distance from parallax, stellar brightness.
3. Ability to read and construct contour maps and profiles for earth and ocean floor topography; the stratigraphic column, atmospheric pressure surfaces; atmospheric temperature structure; seawater density, temperature, and salinity; seismic wave speed; and temperature structure of the solid earth.
4. Ability to read maps of temperature, wind, and ocean circulation; pie charts; graphs; satellite and aerial imagery.
5. Development of spatial thinking by unfolding stratigraphic sequences; tracking continental and polar drift; measuring distances in degrees, hours, and kilometers across the spherical surface of the earth; and visualizing the one-dimensional structure of the earth as a series of concentric rings beginning at the core and extending to the thermosphere.
6. Demonstration of knowledge of plate tectonics by illustrating plate dynamics and calculating the isostatic balance of continental and oceanic crust.
7. Ability to use the principle of "gradient flow" to predict directions of wind, oceanic, and plate motions; the direction of heat transfer; and the direction of transport of scalars such as water vapor, atmospheric trace gases, and saline solutions.8. Proficiency in the use of simple laboratory and field techniques to identify common minerals, rocks, geomorphologic structures, weathering, soils; proficiency to calculate relative humidity, dew point temperature, temperature of a rising air parcel; and skill to estimate energy balance components at the land surface.
Student writing, quantitative ability, critical analysis of web sites, working in groups, use of scientific calculator.
1. Building students' confidence in course- or discipline-related abilities.
2. Improving students' sense of healthy skepticism.
3. Developing students' appreciation and understanding of natural hazards.
4. Increasing student excitement/personal wonder about learning about the Earth.
5. Changing student attitudes toward science.
6. Developing students' sense of stewardship of the Earth.
7. Use of field trips to build cameraderie, tie theory to practice, and offer students strenuous physical workouts in natural environments.
