Milankovitch Cycles Precession and Obliquity
Provided by: Khan Academy |Published on: April 27, 2021
Videos Grades 6-8, 9-12
Synopsis
- This Khan Academy video discusses two of the Milankovitch cycles: precession and obliquity.
- These changes in the orbit and spin of the Earth cause natural changes in climate on geologic time scales.
Subjects: Biology, Earth and Space Sciences
Authors: Khan Academy
Region: Global
Languages: English
Teaching Materials
Positives
- This video will help students understand the wobble, change in orbit, and change in axial tilt associated with natural climate change cycles on Earth.
Additional Prerequisites
- Students should have a basic understanding of the importance of the Sun for life on Earth, Earth's orbit, and the tilt of the Earth's axis.
Differentiation
- Using a globe and basketball could be useful in demonstrating these changes, especially if you have students help you with the demonstration.
- Other resources on this topic include this video on Earth's seasons, this digital text about the effect of atmospheric circulation on climate, and this video on Earth's rotation and revolution.
