Earth Science 105: Earth's Climate: Past and Present
Huybers Orbital Animation Exercise In this section exercise, you will explore the relationship between orbital cycles and high-latitude insolation. Use the animations on Canvas, which are listed as:
-
Download Orbits movie (Huybers)
-
Download Insolation movie (Huybers)
in Week 7 to complete this exercise. I have provided some extra information about these in a powerpoint on Canvas (OrbitalSection.pptx). If you work directly with the word file, please type your answers/work in a different color so that it is easy to differentiate from instructions and questions. You must submit the file before the start of your section in the following week.
1. What are the names of the Milankovitch cycles, what do these cycles refer to, and what are the periods of each cycle? 2.
Briefly define aphelion and perihelion in the context of the Earth/Sun system. 3.
Use the orbital cycle animation to identify each time that the NH summer aligned with aphelion or perihelion over the past 100,000 years.
