Discover times when the North and South poles actually swapped places.

Over millions of years, chemical changes can "edit" the file, adding new layers of data. 📽️ The MP4 of Geology Nrmgzmp4

If we imagine the Earth’s history as a massive video file—let's call it the —scientists act as the video editors. By studying these magnetic "time stamps" in rocks, they can: Discover times when the North and South poles

Natural Remanent Magnetization is the permanent magnetism locked into rocks when they first form. Just like an MP4 file captures light and sound, NRM captures the at a specific moment in geological history. By studying these magnetic "time stamps" in rocks,

This is the "original file," recorded when a rock first cools from lava or settles as sediment.

When we think of an , we think of a container holding a moment in time—a birthday party, a tutorial, or a movie. But did you know the Earth has its own "recording format" that’s been running for billions of years? In the world of geophysics, we call this NRM , or Natural Remanent Magnetization . 🎞️ What is NRM? (The "Raw Footage")

Opening a standard MP4 is as easy as a right-click, but "opening" NRM data requires . Scientists use these tools to measure the intensity and direction of the magnetism, effectively "streaming" the history of our planet's core. 💡 The Takeaway
