Seafloor spreading

Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other.

The seafloor is spreading just as we speak! Did you ever think the seafloor could be spreading? Below is a diagram of the seafloor. New sea floor is produced when tectonic plates split apart. Then …

Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid-oceanic ridge.

Teaching kids about divergent boundaries

In this experiment, you'll make a seafloor spreading model to learn more about how plate tectonics work and create mid-ocean ridges.

The idea that continents drift over time dates back to the 1500s, but it wasn't until the 1900s that scientists figured out plate tectonics.
