How can we use the ocean floor to learn about the history of Earth's magnetic field? In this lesson, students will learn about the driving force behind Earth's magnetosphere, paleomagnetism, and why Earth's magnetic field is vital to life on our planet. I use this lesson when we are learning about the layers of the Earth and the molten outer core.
