Why do Africa and South America fit together? Anyone who’s ever looked at a map can see that Earth’s continents are kind of like a jigsaw puzzle. The idea that continents are constantly moving and weren’t always in their current spots is a pretty obvious idea, right? You might be surprised to learn that geologists only accepted that idea recently in the past few decades, and it figuring out how plate tectonics and continental drift work required some pretty strange evidence.

This video satisfies the 2-ESS2 Earth’s Systems requirement for second grade proficiency.

Students who demonstrate understanding can:

ESS2.A: Earth Materials and Systems
Wind and water can change the shape of the land. (2-ESS2-1)
ESS2.B: Plate Tectonics and Large-Scale System Interactions
Maps show where things are located. One can map the shapes and kinds of land and water in any area. (2-ESS2-2)
ESS2.C: The Roles of Water in Earth’s Surface Processes
Water is found in the ocean, rivers, lakes, and ponds. Water exists as solid ice and in liquid form. (2-ESS2-3)
