Activity

Calculation of the Magnitude of Lunar and Solar Tidal Forces on the Earth part of Quantitative Skills:Activity Collection
Extra-credit project in which students calculate the magnitude of lunar and solar tidal forces on the earth. Students find physical and orbital parameters about the earth, moon, and sun. They use these parameters in four applications of Newton's law of universal gravitation to calculate the difference in lunar gravitational attraction across the earth and the difference in solar gravitational attraction across the earth. Students use these differences to demonstrate that the solar tidal effect is about 46% that of the lunar tidal effect on the earth. They calculate the relative magnitude of the solar tidal effect to the combined solar/lunar tidal effect for spring-tide conditions. Students draw five process diagrams prior to any calculations.

Other Contribution

Introduction to Earth System Science part of Quantitative Skills:Courses
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.
