71% of the planets surface is covered by water, yet we have explored less than 10% of our oceans. This powerful system produces half our oxygen, regulates the climate, and provides us with food, medicine, and a source of recreation. There are many ways in which we can study the ocean and all its processes including the four main types of oceanography: geological, physical, chemical, and biological. *This lesson will primarily focus on geological and physical oceanography* Lesson Includes: Why we study the ocean, continental drift/seafloor spreading, plate tectonics, geological features of the seafloor, waves and tides, gyres and currents, ocean zones, examples of pollutions. *Topics covered in this lesson are inherently more advanced than others. Recommended age: 5th grade and up.* Lesson Length: 38 minutes 30 seconds If you do not receive the automatic email with lesson access information after purchase, please email us at [email protected].
